There are three at the rear of the projector. I only had one making noise, but I ordered all three, just in case.

Please let us know how easy it was to replace the fans.

Hello forum, I’m not too much into blogs, forums or chats, but I found that Dwin’s current status gave me little choice. First I’d like to say thanks for all the great advice from just about everyone. Secondly I wanted to share my problems, troubleshooting and solutions.

I too had a problem with my PJ video shutting down about five minutes after lamp ignition; although the fans ran there was no picture. The projector is hung from the ceiling and is in the inverted position. I reviewed the recommendation to flip the lamp and felt that I could not go wrong giving this a shot. Well I was surprised to see it worked. I will order a replacement shortly as I have go 3642 hours on my current lamp.

I also had a problem with fan noise (kinda sounded like grinding), as the PJ was new at the time I returned it to Dwin and they repaired a faulty fan and returned it. That process took about a month as I recall which was too long for me. At the time of purchase, I felt that this little known company would make it difficult to get the service I would eventually need, but the picture quality was so good to both my wife and I we decided to give it a shot.
I have also had a bright spot on my display; I believe this was a result of my cleaning technique. I used compressed air to blow out the projector, but had the can of compressed air turned almost upside down. This resulted in an oily spot on the lens which was transmitted to the screen as a brighter image than the surrounding video. After about 100 hours of use the bright spot vanished, possibly because the oil spot evaporated.

I have owned the PJ for about four years and I’m truly happy with it performance. I’m sure there are systems out there that perform better today, but I can’t justify replacing it after I sit and watch a movie with family and friends, they too are always blown away.

My explanations were fairly limited in detail, but I will share step-by-step for anyone who may experience any of what I mentioned above. Again thanks for all your help.

If anyone needs a TV3 lamp, I have at least one. My TV3 has been out of service for a year replaced by a marantz.

PM is interested.

Please let us know how easy it was to replace the fans.
Fans are easy to replace, just splice into the existing harness, don't need to go all the way back to the original connector.
Relamped bulb frome Relampit works perfectly so far. There turn around tiime is very quick. I sent it out on a Tuesday and had it back the following Tuesday.

Hi everyone,

I also had my center fan replaced twice by DWIN before they disappeared. This time I contacted the fan manufacturer directly and he explained the problem as the difference between an 'H' and a 'B' in the model number.
"I assume the reason for failure is bearings. The Hypro (AD7512HX-LF) does not tolerate heat as well as ball bearings. Try PN AD7512HB-LF. Your fan can be ordered from Mouser Electronics at mouser dot com or 800-346-6873."

- Brian

still have a bulb possibly two if someone is interested. My PM box is now empty so anyone who tried to contact me please give it another try.

Hi,

I'm looking for a TV3 in working condition. Please PM me if you have one for sale. Thanks!

Just PM'd

Anyone know where these can be found, or if anyone has a spare cable they would like to get rid of?

I have a friend who has the Dwin and called me to ask for help. Since I am not sure whats up with Dwin, can anyone let me know what up with them. I know they have closed and were still doing warranty work, is the warranty work now gone also? Has any other company stepped forward to work on the projectors?

Projector lamp services or relampit.com can do their lamps if he needs a lamp. They did a great job on mine.

Long time I have been away from this Forum...how surprised i was to see Dwin tv3 owners thread on the first page!!!!

well i am back; time to move on...now to find out what i missed in the past year.

The reason they are on the first page is because they went out of business and everyone is freaking out about lamps and repairs. Its sad they left all dwin owners high and dry...

I hope they took care of warranty work and only closed their shop once their all of the projectors fell out of warranty. AS for the the bulb and repairs, I dont blame them for not being around. If they were losing money when full operational, why would they stick around and bleed money just to fix projectors. They should have however made their source of bulbs available to everyone

I have a TV3+ and it gave way to a SIM2 HT380.

The Dwin just displayed a solid white screen so I assume the power supply and bulb are good. BTW, if you can get a bulb they are not hard to replace.

I will let the PJ and outboard scaler IO box go cheap. So PM me with offers!!!

relampit.com sells bare lamps for all the dwin models.
Call Jon at 631 244 0051 ext 110. Very nice guy and very helpful

Anyone with any extra or a source. I have a donated projector, but no cable to make it work.

Hi Steve. I tried to relube the fans to eliminate noise. Worked OK for a while, but grinding sound back. What happens is when you power up, one (or more) of the fans doesn't power up at start, then after a while it comes up with grinding sound, then after 3 - 5 minutes it stops grinding as it warms up. Gets quieter and quieter til it stops.

Anyway, would love to replace these fans. No problem removing 2 of the 3 fans, but the far left fan you had to remove the power supply and it had screws that were very hard to reach with any std tool I owned. I am not very mechanically inclined, but I did not see any easy way to get at that 3rd fan. What I am missing here?

soon to be former TV3 owner. just found a great deal on a Sony hw10. i look forward to quiet more than anything else.....

any one else make the same swap?

do i sell my TV3 for parts?

Hi there...my first post...I'm not allowed to provide a URL until after three posts, so I'll just have to refer to a few websites.

Last night, I heard a "pop" after my PJ was on for about 30 seconds...then the image on the screen went away. Pretty clear indication that that bulb blew. But if anyone thinks it could be something else, please let me know.

As I'm researching purchasing a bulb / rebuilding the lamp assembly, I see several recommendations on this thread to send my lamp assembly to Relampit and have them set a new bulb in there for me, but I also found an entire lamp assembly for $195 at replacementlightbulbs.com. It appears to be the same housing that is in my DWIN TV3.

Another site (Brauchla TV and Appliance) offers DWIN TV 3 bulbs for $239, but at that price, I would just follow the advice of others on the forum and send my lamp assembly to relampit.com.

Any suggestions?

I just ordered my replacement bulb from Relampit. They will send you a bare bulb if you want. My bulb had 3800 hours on it, and it was starting to get pretty dim. I'm perfectly happy with my DWIN for now, so I see no need to upgrade.

They can send you either a bare lamp or relamp your housing if you do not feel comfortable doing it yourself for a little more.

Just replaced my lamp from Relampit (I did it myself). Works great so far. All I can say is that it sure is a lot brighter than the one I had. Then again, I had close to 3800 hours on the last one.

My TV3+ [ my first love, it has been replaced with a SIM2 HT380 ] only puts out a white light so to speak.

Thought about making it the gaming rig for the oldest son.

I think that is a good idea. It isn't worth anything on the open market, so recycling it whilst making your kid happy is a win win.

As Jason said, it cant hurt. Im sure he will be happy!!

then i guess i will have wasted the $5 on my AVS classified ad. i just listed my TV3 tonight, and hope to get some interest....:cool:

Just curious, how much are you asking?

I'd be surprised if you got much interest, but who knows.

i will take best offer, but prefer local pickup, as shipping would be a big piece of the value.

i got a few bites so far...mostly few hundred dollar area. alternatively, i could give it to my brother-in-law.

Okay, so I picked up one of these at a price low enough that it is worth the risk. Due to economic conditions, etc. I am trying to piece together a quality home theater experience on a budget. 1080p would be great, but I figure that at my seating distance of 1.5x screen width that the DWIN will throw a better overall picture than these el' cheapo new 1080p's. The unit I am receiving only has 215 hours, so it SHOULD have a lot of life in it, and hopefully it is as perfect as described by the seller.

My question is, will the transcanner accept a 1080p/24 signal, and likewise will the projector output at 24 (48) hz? I am doubtful that it will, but it would be a nice bonus!

Thanks

Andrew

Most set the PJ up with 720p x 1280 sources. The Blue Ray should output that too for those who don't have a true 1080p projector. I never got ther chance to try Blue Ray player on my Dwin so I can't compare.

Many have had lots of enjoyable viewing hours with the Dwin. I still have mine but obviously, prefer the 1080p Benq I have.

That is what I plan to do, send 720p scaled in player over an HDMI to DVI cable. Was just hoping for the moon that it could scale down a 1080p source and play back at 24fps.

Well, I think what I just got is a steal of a deal. Only 215 hours on the projector, works perfectly, and I am only out $450.

Actually, a damn good picture for $450. I will only be using my Panasonic Blu-ray via am HDMI to DVI cable. Thankfully it handshakes perfectly.

No remote was included. I have a Pronto TS1000 remote, but the only codes I found were for the ProntoPro. Any advise on getting the proper codes? I really only need power on/off.

Also, are there any advanced control options? The only picture options are Contrast, Brightness, Color, Tint and Sharpness. How do you access RGB controls for proper calibration? Perhaps I need the remote for this.

And I am not sure if this is a TV3 or a TV3 plus. Anyway to tell the difference? No manual came with it, either.

Check remotecentral.com for codes for the dwin tv3

This is my first post here. I have a Transvision 3 (installed in 2004) that has been terrific in our theater and operating perfectly until recently. Does anyone know where/how I can obtain a new power supply for the processor? With Dwin out of business I would consider buying a used TV3 for parts. Any ideas?

Hello! Does anyone think the silicone in the bulb housing is there for a reason? I'm not an engineer, but my first thought was that it might help dampen the bulb from slight vibrations such as caused by the fans.

Sadly I just found out today that Dwin is no more. I (think I) am in need of a bulb. Mine goes out after about 45 seconds but fan stays on, similar to what others are describing. It's especially a pity, given that I had always stocked at least one spare lamp, except this time.

I think I will try the upside down trick as my PJ too is inverse mounted on the ceiling. That got me to wondering about the silicone. I guess if I can get any more life out of this bulb it's a bonus, as I was about to replace it anyway.

Anyone who sent their bulb to relampit, did you notice if they re-apply the silicone in the same way?

I'm also going to look for more info on the fans. Saw the post with the difference between HX and HB. Does anyone know if different fans altogether will work? I had always daydreamed that I would one day replace the fans with the quietest ones I could get my hands on. I've used Silenx in the past to quieten computers, but never checked if they make the same size/speed/airflow that are in the Dwin.

cheers,
Albert

When mine did that it was because of the cnter fan not turning. I would hear fans but it was the two outside fans in the back. The center one was not spinning due to dust, I cleaned it and it seems to have fixed the problem. I did buy a HB version of the fan from Mouser and will probably replace the center fan

Here is the link for the fans I purchased. http://www.futureelectronics.com/en/technologies/electromechanical/thermal-management/fans/Pages/5535299-AD7512HX-LF.aspx

Hi Steve, did you have any luck with these fans? Did you notice if they were quieter or louder than the factory fans (pre-problem)?

I just checked their spec sheet, and notice the non-ball bearing fans (Hypro) are 75x75x30 @ 3kRPM, 10.3CFM, 12V, .30A and a whopping 38.5dB/A.

The same fan with ball bearing is 75x75x30 @ 3kRPM, 10.3CFM, 12V, .24A and still 38.5dB/A. I suppose with 3 of these fans, the resulting dB/A would be near 46dB/A.

To contrast, I checked my trusty Silenx vendor. They do not have a fan the same dimensions. The next smallest is 60x60x25 @ 1.7kRPM, 14CFM, 12V, .08A, and a measly 12dB/A. With 3 of these, the dB/A would be near 15. Huge difference.

I don't know how they do that. It's a smaller fan, slower revolutions, yet almost 40% more air movement and many times quieter. Unfortunately I did not see the pressure specification for this fan (there was one listed for the ADDA fan). I also did not see any indication of heat tolerance.

Please excuse my ignorance, but if it were possible to properly construct some kind of adapter that would fit these to the 75x75 mount, is there a good reason to not use three of these fans instead of the factory ones?

Perhaps a better question is, does anyone make a 75x75 fan with similar characteristics as the ADDA, but with noise characteristics similar to that of the Silenx fan. I'll keep looking.

Lastly, anyone know if these are other fans in the projector that contribute to the modest noise output of the projector?

I ordered two replacement lamps from replacementlightbulbs.com, cited earlier in the thread, and the first seems to be working fine. I took the existing lamp out of the metal bracket, being careful to leave as much of the silicone attached to the metal bracket as possible. By the time I got the lamp off, almost all the silicone remained on the bracket. I installed the lamp (upside down) to the metal bracket, and tightened the screws that hold it in place. I centered the lamp on the bracket as well as I could and tightened the screws. Leaving the silicone on the bracket seemed to work as it provides some cushioning.

Fired up the projector and voila -- no more shutting off after ~ 40 seconds. Hopefully this will last as long as or longer than the previous bulb, about 2300 hours!

I saw the 3 fans along the back of the projector and decided to postpone trying to replace them to a later time. I did also see one other fan inside the projector not far from the color wheel. I also gave the unit a good dusting, it was filthy!

Now it works great again. I love the picture. Now off to get a Blu Ray player......finally! :)

Hi:
just wanted to say that I bought the Dwin TV3 from Robster1958.
I must say I was quite surprised by how good it was.
I bought it for the kids, but installed it in my HT out of curiousity.
Very dim (so doesn't give that pop, wow ), and very loud. But the PQ reminds me a lot of a CRT - it has a lot of depth to the image and the skin looks very realistic - not digital.
Shame about the brightness as I was so impressed I considered keeping it for myself instead of paying over 10x the price to get a new projector this year from Jason.
:-)
oh and btw it was a pleasure meeting Rob - nice guy and even dropped it by my house when he ended up near my neighborhood.
thanks Rob!.

Try adjusting the brightness or get a new bulb if there are a lot of hours on the bulb. Mine is still pretty bright and I love the quality of the image

btw - this sounds like a stupid question - but, how do you turn the projector on with the remote. I've tried the power button,but it didn't do it. I need to press the power on manually.

Well, I think what I just got is a steal of a deal. Only 215 hours on the projector, works perfectly, and I am only out $450.

Actually, a damn good picture for $450. I will only be using my Panasonic Blu-ray via am HDMI to DVI cable. Thankfully it handshakes perfectly.

And I am not sure if this is a TV3 or a TV3 plus. Anyway to tell the difference? No manual came with it, either.

The advanced features are available only through the service menu. PM me and I will see if I can dig it up.

You can't tell whether it is a plus or not. It is an internal mod unless it was purchased new as a plus and then I am not sure if there was a different badging anywhere.

Hi Rez Projection in Ashland MA repairs Dwinn projectors.

Looking for any help and/or suggestions. I thought my lamp was going out. The projection would stay on for about 20 minutes the go out. Kept happening so I ordered a new bulb from relampit.com. Switched out like usual. Didn't fix the problem, blacked out again after 10 minutes. Now here is the weird thing, have it goes black a few minutes later the screen lights up white but if you try to access menu or any thing else. Nothing shows up, just white screen. Any ideas, is the video processing going out??

Have you checked to see if the fans in the back are working?

i have not checked that. A few months ago I know one was making a funny noise. Its possible that one went out. So do I just plug it in without the cover on? If one is out, is it an easy fix?

On the back of the Dwin there are vents that run the width of the back. Run your hand along the vents and see if you feel air blowing out. There are three fans, on mine the middle fan made noise and then froze

so what were the results? did you start to have the same problems i described above? and were you able to fix it? i am starting to think that I just start over as in buy a new proj.

My picture would flash on and off and go to a bright screen. The middle fan had stopped turning. I bought a new one and replaced it and all seems fine. I will replace the other two fans also just in case.

Firstly,

I have a question pertaining to lengthening the cable that came with my TV3.
I have it currently on a 25 footer. However it is not long enough and is quite unsightly to my wife.
Would I be better off sourcing a longer used TV3 cable or
could I extend the cable with various off the shelf DVI cabling.

I was wondering how off the shelf hardware might impact signal loss/picture quality etc...

Secondly,

I am looking to at last setup a blue ray solution with my TV3. Any recommendations on hardware, conversion cables etc...

Regards,

gralet

I apologize if this is the stupid questions, but i have just recieved an Dwin TV3 that was no longer wanted. I tested it out it seems to be working fine so i want to continue the process and actually install it. However I do not know the first thing about setting up the projector itself or anything with distance and screen size and ratio. Any help would be great.

I did a search & found I have a .pdf file that says Dwin Manual. If you haven't already gotten what you want, sent me an email to wmalcolm.clark@gmail.com and I'll email it back to you as an attachment. I am still using my Dwin Tv3e (or something similar). Had problems with it bulb cutting off, but the trick mentioned various times in the forum worked for me: take out bulb and turn it upside down (assuming a ceiling mount). I did this sometime last year and it has worked since without the bulb ever cutting out.

I am out of town this (extended) weekend and preparing to leave today. So if you email me for the manual, I may not get to sending it until the middle of next week.

Malcolm

Thank you!

Now I know Dwin is out of business and the website does not work so where do I go for the throw distance calculator?
Thanks again

I saved it off as an MHT a long time ago (you'll need to use Internet Explorer); I've put it up here for you to try - I'd suggest saving it off as a local MHT, too:

Thank you for the link, I found one on projector central. According to the list if i want 120 inch screen the throw distance should be 13'6". However im not sure what the Diagonal range is. It says with those measuments the zoom is 1.36x. I am not sure what that means. Also is there anything else i need to take into account?

Is there an easy way to replace the Fan behind the power supply? One of the lid screws is behind the lamp box. The other two are easy.

I did not see this answered before. Sorry, if this is a repeat. This thread has be a great help for me over the years.

Thanks,

Kevin

Never mind. I found my own answer after changing the search criteria. It is at the top of page 75. Thanks Don. (if you still read this thread)

I am about to replace my TV3 with a new projector. Since the cable from the box to the projector is already in my ceiling, can I reuse it in anyway with a new projector? Or is the cable useless?

I am about to replace my TV3 with a new projector. Since the cable from the box to the projector is already in my ceiling, can I reuse it in anyway with a new projector? Or is the cable useless?

I am 90% sure that it is useless.

Not completely useless, since it's nice and thick, you can probably tape a new cable to it and pull it through, without worrying about breaking the Dwin cable. Unless it has sharp bends or is stapled etc.

I added some new cables in my ceiling, HDMI and Toslink, and used an existing (but unused) audio cable to start pulling (pulled new cable plus some strong string, which I left and can use to pull things in the future).

I have spent the past year repairing approximately 30 Dwin TV3 and TV4 projectors. I would catagorize the failures as follows:

1. Stuck fans - its amazing how much crud can build up in the fan housing and on the fan blades as well as within the enclosure that the fan is cooling. A can of compressed air, a small paint brush and a handful of Qtips soaked in rubbing alcohol can do wonders in resolving these problems.

2. Bad power supplies - the power supply chassis in the TV3 and TV4 are very similar. Each contains an open-frame switching supply for the digital circuits, an Osram ballast board to generate the high voltage drive for the bulb, and a Dwin-designed supply board that contains the circuitry to convert the incoming line voltage to the voltage needed to drive the Osram board as well some relays and line filters. I have found the Dwin board can be problematic due to less than optimal design and component failures.

3. Bulb failures - If the bulb de-illuminates (is this a real word?) some time after the projector is turned on, the problem will be either a bad bulb (easy to check by swapping in a new bulb), the thermostat (easy to tell by disconnecting it) or the Dwin power supply board. I have rarely (never) have seen a thermostat failure although I have seen a few fan failures. The fan can be disassembled and repair or just replaced. I have seen some bulb failures and resolved the problem by installing a new bulb. I have seen many power supply failures which involve removing the power supply chassis, opening the power supply box,disconnect and remove the Dwin power supply board, diagnose the problem, replace defective parts, and reassemble. Dwin did not design the power supply chassis for easy access (the TV4 is a real headache to work on due to it's smaller size).

4. Wires breaking off the chassis-mounted 13 pin DIN connector. This seems to happen more often on the TV4.

5. Sticking color wheel - if the projector accumulates a lot of internal dust,the color wheel motor or the optical rotation sensor can become occluded. Use lens tissue to clean the LED and the photodetector and some compressed air,Qtips,and light machine oil to clean the color wheel motor. Be careful not to touch the colorwheel itself; it is very fragile. Use some compressed air to blow dust off of it if necessary.

6. Very rarely will you seen a problem with the Transscanner box. The only one I found had failed was due to an open-frame power supply failure.

If you have any additional questions or need help, drop me a line. If you have a non-working Dwin projector that you want to get rid of, let me know. I like to have a good spare parts inventory.

Over the past year, I have repaired over 30 Dwin TV3 and TV4 projectors. I was unable to fix another 5 units due to catastrophic failures of the digital control board. Since Dwin did not make schematics and source code available, the digital control board is extremely difficult to repair, let alone get access to.

Of the units I did successfully repair,the problems fit into the following catagories:

1. Clogged fans,dust buildup inside the chassis. These can cause overheating which causes the lamp thermostat to shut the lamp off. If the fan cooling the power supply fails or blows too much dust into the power supply chassis, the power supplies can fail.

2. Power supply failure - there are three discrete power supplies inside the Dwin power supply chassis. One supply is an Osram ballast board which supplies the 25KV for the lamp. Another supply is an open-frame switcher to supply the digital logic. The third supply is a Dwin-manufactured board that supplies the proper voltage for the Osram board as well as contains the safety relays that switch off power in the event of problems. The Dwin board is the most problematic of the 3 and requires a significant amount of disassembly to access.

3. Lamp failure - this can be checked quickly by substituting a known good bulb for the suspect one. If this doesn't remedy the problem,then most likely the problem is the Dwin power supply board.

If you need help, let me know. If you want to dispose of a broken projector, let me know.

I had this thread subscribed to so the new posts just reminded me about mine.
I have one that got demoted from my dedicated HT to playroom - however since my youngest gets scared with the lights out - I haven't used it. So I'm selling it - note - it works great, so I'm not giving it away, but will sell it for a fair price. Pick up in NY preferred as it requires 2 boxes to ship. you can PM me.
mods- this is not a big ticket item, and not a profit making thing, and I'm posting as people in this thread are looking for them. If that's a violation of forum rules I apologize and by all means delete the thread.

I posted a notice in the classifieds (Front Projector) for a non-working TV3. Motivation is not to make a profit, but to make it available to someone that can use it. So make an offer (any offer!).

My problem is no light at all, fans go on, color wheel starts up then shuts off after about 30 seconds, power light starts to flash rapidly and unit powers down. Any clue if this could be just the bulb or something else? I would love to repair this rather than start putting in new wiring into my ceiling so suggests on fixes appreciated

Sounds like bulb. I just bought one from bulbtogo.com $175.

Could be thermal too. Make sure all 4 fans are clean and that there is no dust build up inside.

if i remember correctly, the cable had some type of proprietary connection on one end, so while the cable itself is fine, you wont be able to connect it to a new projector

all the fans seem to be working. Does anyone know of someone reputable who would work on a DWIN pj these days?

Does anyone know how many parts (if any) are shared between the Transvision 3 and 3+?

I've replaced my TV3 so it's available, PM me if you're interested. Been sitting on the floor in the back of my media room since Thanksgiving 2008. Works fine for 30 to 60 minutes then screen goes black. Power down then up, and it works again for a while (~10-45 min), then black again. Usually happened one to four times in a typical movie. Drove my wife crazy but I didn't mind the excuse to grab a beer while the unit powered down until the fan shut off :-)

Likely one of the common problems mentioned by JakeHarris. I never tried replacement bulb, or turning bulb upside down etc., as I got a great deal on a replacement projector which I needed on short notice (my wife can be persuasive when she wants to be :-))

Yes as Daniel said the cable is proprietary, it's standard DVI on the end that goes into the scalar box, but on the projector end it's a proprietary round DIN style connector. I think my cable is 30 feet.

Does anyone have a DVI - Dwin DIN cable that they are willing to sell?

i have a perfectly working TV3, but needed to use the cable at an existing client's house. Please let me know.

this is the projector that wont die

I still love mine!

Sounds like bulb. I just bought one from bulbtogo.com $175.

The one they list for the DWIN is $500. Did you find a different one on there?

My "parts projector" arrived severely damaged, so I seem to be SOL when it comes to fixing my projector. If anyone has one with a bad ballast or bulb, I could take it off their hands quite cheaply; alternately, if you'd like to buy a ballast or brand-new 100% original bulb, I imagine I could work something out...

Thanks. It wasn't coming up under an "OSRAM" search. I did find it eventually:

I'd love to mention something good about my projector but I fear I will jinx it. Only bad thing is it has a rubbing noise during a cold start-up. Kind of like the color wheel is rubbing something. I have opened it up and that is not the case. Haven't taken the time to diagnose the problem. Hard to do with the proprietary cable run through the ceiling and the projector hanging.

Noise could be a fan in need of cleaning or replacement

My TV3+ was making lots of noise on start up. I replaced the fans and it went away. Very easy to do thanks to Don's post. I think one of mine was actually dead as now shut down is faster.

Kevin

well, i hope you can get yours fixed, but if you can't, hopefully we can work something out (either i buy your cable, or i can sell you my TV3)

Is there anyone out there that can repair a TV4. I sent a private message to Jake Harris but never heard back.

The symptoms are simple. The TV4 will not turn on without multiple attempts. I replaced the bulb @ 2000+- hours when I was getting the same symptoms. It usually takes 4-5 tries. The second to last try the bulbs turns on for a few seconds and shuts right back down.

With the new bulb I could not get the projector to tun on @ all until I flipped the bulb 180 degrees. All fans function, all have been cleaned.

I am perfectly happy to keep this projector if it can be fixed.

Any thoughts out there?

Once on, it will function properly forever....

What's my old TV3+ worth?

What's my old TV3+ worth?

Nothing.

:(

That's double what I thought!

That's double what I thought!

You should be pretty happy then!

I have a TV3 parts projector and DIN cable laying around if anyone is looking for parts.

That's double what I thought!

Just replaced the bulb and three fans. It might still be worth nothing after investing $200, but the picture certainly is not worthless!

Guys,

Have a problem- switched the TV-3 on tonight to watch MNF. The fans come on, bulb does not come on, the green light on the controller starts to flicker, the red light you can see inside on the front of the projector also flickers and after about 3 minutes it shuts itself off. any thoughts are greatly appreciated.

Thanks,

How many hours on the bulb?

Just changed the bulb and the three fans at the back- about 30 hours on the bulb.

I would make sure the dvi cable is seated all the way. If that doesnt do it check the connectors for the bulb to make sure they are tight. If that does not help fire it up with the case open ( you will risk dust blobs) and she if that works.

Thanks, I'll give these things a try when I get back into town after the holiday.

Best,

Need Some Guidance. I have a TransVision 3e...purchased and installed in 2005. It's been working fine...a few bulb replacements..all good. Just replaced the bulb about 3 weeks ago and the other night we turn on the projector and no light. Swapped out the lamp with the spare...still nothing. Projector will start up...lamp will not light...and then the projector will turn off in about 45 Seconds. The green light on the scaler blinks constantly and the IR on the projector continues to blink. Any thoughts of advise on a possible troubleshooting or fix would be appreciated. Thanks..Brian

Try unplugging both the projector and processor to reset them.

Thanks...tried...no luck...same symptoms....Brian

do all 3 fans in the back run?

Trying to check that, but can't get the projector to come on when plugged only to A/C when not on the ceiling mount. Is there a on/off override on the unit?

I have, in a corner of the spare bedroom, a TV3+ that when it was last installed [3+ yrs ago] only put out a white light. I guess should hook it back up to test.

Any suggestions on what might be the problem? Any one [Vegas Homes] want to pay "something" for its parts value?

Trying to check that, but can't get the projector to come on when plugged only to A/C when not on the ceiling mount. Is there a on/off override on the unit?
The dvi cable from the processor must be plugged in

Problem: Shut down within minutes or hours and it was not the bulb. The last visible image would show blotched colors as it faded to black.

Initial hypothesis: Is it thermal related? The last seen image pointed to a color wheel issue.

Issues found: A failed fan for the bulb had spewed dust which was now caked in streaks across the color wheel.

Solution: Spary everything possible out of the chassis. Spin the fans to find the faulty one, remove it and swap it for the color wheel fan, temporarliy while a replacement is ordered, well all three actually. Clean the color wheel using Qtips and liquid lens cleaner. Clean LED and optical sensor with lens cleaning cloth. Examine bulb and check for TOP orientation.

Result: No more thermal shut down from a failed bulb fan. A nice bright image as a result of an immaculate color wheel. A need to quickly get some new fans.

I have to thank JakeHarris for his information posted in June. It gave me the insight to dive deeper into my TV3 beyond the usual bulb replacement and cleaning maintenance I've been doing for a few years now. I hope I can continue to enjoy my projector for a few more years with the knowledge shared here. Thanks to all who have contributed to this forum especially when the manufacturer has closed his doors.

I used to test my PJ unit on the work bench absent the DVI cable plugged in by connecting the AC power switched on and using the remote control to turn it on.

Well, I couldn't find a Dwin TV4 owners thread so I thought I'd post here.

I just built my first home theater. My friends love to poke fun at me about this since I haven't even owned a TV for the last 10+ years! My wife & I watched TV shows and movies on a 14 inch laptop. I'm a big XBox gamer, and have always played on my hi-def computer monitor. Music on the ipod, etc etc etc

But thanks to the fact I moved next door to a home integrator a few years ago, my outlook in life has changed :). My new friend hooked me up big time and I was able to buy Monitor Audio speakers, Denon receiver and a Dwin TV4...all at his cost.

Now, I know the Dwin TV4 is considered an obsolete system (720p, no HDMI, out of business, etc), but let me just say this projector ROCKS. First of all, I got this brand new on wholesale clearance (89% off my neighbor's wholse cost!). Second of all, the picture is waaaay better than any of my friends who have spent way more buying 50+ inch 1080p flat screens at Best Buy. I can go on and on...

I've spent the last hour reading the posts on this thread and was very hesitant of posting this. Most postings are from owners that have owned their TV3/4 for years (and probably paid thousands) and are in the process of seeking for replacement parts or in need of repairs. But I figured this post would remind you all just how great this projector is, and you probably haven't heard from a new proud owner in years.

Anyways, I'll close off this post. Proud owner of the TV4. XBox looks great when it's 100 inches.

Welcome to the Dwin family. I'm glad you are enjoying your TV4. My TV3 still gives me a stunning image after seven years of ownership. Dwin's processing is first rate.

Does anyone out there have a transvision4 or transvision3 scaler box which they would be willing to part with?
Bob

I saw one for sale on eBay just two days ago...no longer there. You just missed it :(

So after 7.5 years the original bulb in my projector went out. Had to turn to the bulb over a little while back to keep it going. How many hours did it have? I didn't want to look for fear of jinxing it. Guess it's time to get another bulb and probably replace some fans. I'm fine with the picture from the DWIN and don't need anything else... yet. I have seen some of the new LED TVs with the high refresh rates and wow they have a really good picture.

Anyone have a replacement model number on the small fan next to the bulb? I found the case fans for $14.42 but they have a $50 minimum purchase. Figured I could get the small bulb fan too and be over that price.

Toxarch,

I took a look at your HT Website and have a few questions.

(I have the TV4)

First of all, I notice you modified your projector unit by installing a custom filter system. I've read some earlier posts in this thread and it seems that dust is a bit of a "concern". Should I be concerned with the TV4? If yes, is there any advice on how to mod my projector?

Second of all, since we're on the topic of modifications...my only complaint with my TV4 (apart from the occassionaly "hand shaking" issues with connected components) is the fan noise. Does anyone know of an aftermarket fan that can provide the necessary cooling at a lower noise level?

Thanks!

I am not familiar with the TV4. But seeing how DWIN continuously ignored the filtering on all the previous projectors, I would bet there is none in the TV4.

As for the fan noise, turn the audio up to cover the noise. ;D You might look into building a hush box for the projector. Then you can filter the air and have a quieter setup. There should be lots of hush box designs on the forum.

Pulled my projector down and fired it up to see which fan was making noise and to put in the new bulb. Opened it up and fired it up. The old bulb still works! I went ahead and swapped it out anyway and I'll keep the old bulb as a backup. Cleaned it out, figured out what the other 2 fan models are and put it back up. It ran for 15 minutes and then flickered and quit again.

Pulled it back down and I think the fan for the power transformer is not drawing enough air through and it's going into a protection mode. I planned to replace the fans anyway. Guess I won't be watching anything on the projector until then.

Here's the fan model numbers:
MAIN 3 fans: ADDA AD7512HX replace with AD7512HB-LF
Small bulb fan: Delta Electronics (Brushless) BFB0512H
DLP chip fan: ADDA AD0612MS-D71GL

Propped open the electronics/transformer box lid and used another fan to blow air into the box. Projector ran fine for 30 minutes. So I will be ordering new case fans as soon as I hear back from one online fan vendor about whether they can get the DLP chip fan for me or not.

When I shut the projector down, it shut down the fans within a minute. That external fan I set up for testing cooled the projector down pretty good.

Hi Gang! I see a few here are still keeping the old Dwin alive.

I've been through a few here since retiring the Dwin, still sitting on my storage shelf.
The bulb quit and I decided to get another to upgrade to 1080p x1920 fpr Blu Ray at the time. Bought a Benq10000w which worked for a little over a year and then the main powersupply burned up. Benq wanted too much to repair out of warranty so I replaced with an Epson 8500. It's been running good and ran through 3 bulbs at 3ooo hrs each. Last month I upgraded to a Sony VPL VW90ES to have 3D. It's a great PJ and is the best PQ I have ever had plus it does 3D which is real fun.

I did replace my entire fan set with original part numbered fans. The bearings finally got too loud for me so I replaced them all. The Dwin also went through a period where it would not work inverted but would run indefinitely right side up. Dwin fixed that for free as a power supply defect when I had the box upgraded to TV3e.

Did someone ever figure out what bulb works in the TV3e? AFAIK, that is all that is wrong with mine but being 720P I don't know how much value it has these days. Heck, were already past 1080p now and people want 3D. Don't know what to do with the old TV3e.

I like the crack about turning up the audio to drown out the fan noise. I have a better suggestion. I will send out my wife depending on the area you live in. I will call her, make her mad at me, it wouldn't take much, just something simple like are you having a nice day dear, and then the noise in response will be more than enough to drown out any fan noise.

Don, I just put in the following bulb from the following site. It's the same bulb as the original and it's plug and play. Or maybe I should say swap and play.
http://www.replacementlightbulbs.com/lamp69362.html

I won't buy any 3D unit until they come out with an industry standard. It's like the HD-DVD vs. Bluray vs. whatever else there was at first. Now we have only Bluray. Same will happen with 3D. Every manufacturer has their own 3D glasses and they don't work on other brands. They are even coming out with 3D screens where you don't need glasses anymore.

That is a great find, and a great bargain. Thanks for posting the link!

For this price it's just the bulb, you have to take the old bulb out of the mounting cage, clean up the silicone on the cage and apply new silicone to hold the bulb in place. Not a big deal, but it should dry overnight before going back in the projector.

No offense but much of your opinion on 3D is out dated.

The only non standard today is the ir frequency which glasses operate. Then you can buy universal glasses that sense and adjust to your brand. Like a programmable remote control which to this day have never been standardized between mfg either.

All bluray 3D today works on all current 3D TV.

All hdmi 1,4a works on all 3D TV broadcast, streaming and gaming 3D is standardized to the hdmi standard with auto switching so you don't need to worry over it.

Even older 3D TV that uses checkerboard display has a converter to take inbound standards and convert. Are all older TV forward compatible? No.
Only obsolete anaglyph works on all displays.


When it comes to the glasses active vs passive, and glasses free, there is a choice depending on how you watch.
Active for traditional home viewing is standard because it permits multi viewer and traditional screens for projector.

Passive requires special curved polar preserving screen and is really for very high end home theater. There are experimental systems but these are not ready for prime time as the PQ is awful.

Glasses free is being used for single viewer application. Like gaming and camcorder monitors.


3D is not for all programming nor is it for all people. It is a special addition to your entertainment, much like a butt kicker or D Box. We like having the option and are entertained by the illusion of watching a screen in stereoscopic view.

So, if you were waiting for a standard, the wait is over. All the standards have been established. If you need glasses that work with 4 different brand TV then you buy the programmable ones and you are good to go. Similar to IR remote controls.




Thanks for the link and info. I will check it out later. Not sure what to do with the dwin as i dont think it has any value. Almost like repairing an old CRT?

For this price it's just the bulb, you have to take the old bulb out of the mounting cage, clean up the silicone on the cage and apply new silicone to hold the bulb in place. Not a big deal, but it should dry overnight before going back in the projector.

I wouldn't pay extra for a monuting cage. The old one is metal and will last a long time. Also, there is no need to silicone it in that I could see. The screws and tabs in the 2 corners are more than adequate to securely hold the bulb in place. Mine hasn't had any silicone since I turned the bulb over long ago.

That is a good price on the bulb. I may just buy one and get my Dwin working again. Not sure what I will do with it.

I agree with the silicon part. I've rebuilt my bulb cages before and I don't recall any silicon on the original???? Seems it gets too hot for that.

I don't think the silicone, works as a glue, more for cushioning. There are several areas inside that seem to have a drop of silicone to keep things in place. As tricky as this things are- turn the bulb upside down and it works, hold the remote under your left armpit when pressing the start button and it will come on- I tried to make everything just the same as it was when I put the cover back on.

If you use an IR repeater, then you will have problems with the remote. The thing is, the scaler has an IR input and the projector has an IR input. Your remote signal bounces off the screen and back to the projector. If it receives a signal at the projector and at the scaler at the same time, then it won't accept the signal for some reason. Either remove the IR repeater from the scaler or cover up the sensor on the projector. Then it only gets the signal at one location and it will work fine.

I got my new fans in. Noticed the fan for the transformer box has an inline resistor on the original fan. The other two fans do not have that resistor. Maybe they lowered the voltage on the one fan to drop the airflow on purpose? I'm going to install the new fan without the resistor so it cools better.

Put the fans in. Ran it on the bench. It runs for about an hour and the light flickers and it cuts off power to the bulb. Wonder if it's a color wheel problem. Doubt I could find parts like that for it.

Thinking it might be time for a new projector. If that happens I'll have a bulb with 2 hours on it available.

Same thing happened to me. With it still mounted I removed the bottom case and turned on the projector and it ran fine all day until I put the case back on and it turned the bulb off. I think you still have a thermal problem somewhere.

I think you still have a thermal problem somewhere.

Or the power supply sensor circuits are failing. That's what happened to my TV3 and Dwin replaced the power supply in the PJ. They did it free when I had mine upgraded to TV3e.

Well the time has come. My Dwin has been great but, on one of the lamps I have it runs a few seconds and shuts down. I does work on my back up which has more hours on it than the one I took out. (1200 hrs). I was trying to make it last one more year but am afraid to wait any longer.

I have been working with Mark at AVS and will soon be the happy owner of a TruVue Vango DLP with a LED light source. I got to see it at a gracious AVS Forum member's house on my last trip to the 48.

Also, I got to see the Runco DLP/LED, a Sony (not sure of the model) and an Epson at Hippo's in Albany, NY. (Nice folks and a good display)

Not sure what to do with my Dwin because I don't think it will last too much longer so I don't want to stick someone with it.

I has been back to Dwin once under warranty and I replaced the rear fans with ball bearing ones. Don, thanks again for the tips. It has served well.

I will continue to monitor the thread but can't wait until the Vango is hanging in my Theater.

How much quieter are the ball bearing fans than the stock ones? Do you know if they're compatible with the TV4?

Don't have a real feel for the sound level. One of my fans was completely out and I did not even know until I was cleaning it one day. So my memory was of 2 vs 3 fans running.

I don't see why they would not work in the TV4. IIRC it is the same case and they are mounted at the back of the case and appears to be a fairly standard fan. Maybe someone else has a definitive answer.

It was a really easy change using Don's tips (earlier in this thread) Just took a few minutes. Since one failed, I just replaced them all since shipping to Alaska is often terrible on small items. I did notice how much sooner it the fans stopped after I turned the projector off but, that is most likely due to all three fans running.

Not sure that answers you question but, I hope it helps.

Kevin

Upsetter,

I did a quick check with my Radio Shack spl meter. It only goes down to 60db. To get it to register, I had to almost touch the case at the fan exhaust.

Not sure if that helps. I only hear the fans when there is no sound from the movie. When I am seatedd at my viewing postion, it is not 2 ft back from my ear and mounted on a ceiling mount at about 6' from the floor.

Kevin

I am working a temporary problem, I have my new Marantz AV7005 hooked to my Dwin TV3+. When I use the cable box (Pace) it works just fine. When trying to use my Oppo BDP-83, HDMI will now lock. Even if I convert the Component video, the HDMI output from the AV7005 to the Dwin breaks every couple of seconds. Has anyone seen this with this or other BluRay players? My new projector is in the works so I hope this is a temporary problem.

Kevin

After a firmware update on the Marantz and turning off the a/d conversion for the component signal, I can now route through the Marantz. The HDMI feed works better but still breaks up every few seconds. I hope this is just a handshake issue with the Dwin and will resolve itself when the new projector arrives.

Kevin

We have not been able to locate a cable for our TV3 and processor. If anyone is interested in a working TV3 and processor to use as replacements, spare parts for an existing system they have please let me know.

Putting my Dwin in the box today. I have a new Vango in its' place. What to do with the Dwin? Any ideas? Anyone listening? :)

What model? I love my TV4 and may even buy spare ones if the prices nose dive... I'll need them one day when it's time for repairs

It is a TV3+. It works and has a 40' cable, standard mount and the long allen wrench . I have a spare lamp that has problems but it is a good cage to send for bulb replacement. The back fans have been replaced with ball bearing type.

Since my TV3 went out last year, my HT has been shut down. Waiting for the 1080p 3D projectors in the fall. If anyone is getting rid of their TV3 for cheap, let me know. It sucks not watching movies in the theater.

How many dollars in a cheap? :) Shipping would be a good bit from here.

Take it off line please. Use the PM for this discussion.

Oh Mark Please. You can't be serious. It was a joke. Don't you understand the smiley? The cost of shipping alone from here makes this type of transaction (really cheap projector for a few months) unreasonable on face value. After all, you just shipped me a new projector so you know all too well the cost to shipping to and from Alaska.

I would trade even for a new Adams Golf F11 ti 3 wood. If they would throw in the 5, I would install the thing as well.

Hey Kevin. I just spent last Tuesday and Friday at the US Open about 25 minutes from my house. I understand on Friday I was on TV quite a bit. I spent the entire day next to the rope on the right side just above the 18th green, actually right above the first trap. Was out there during the thunder storm sitting on my USGA tripod seat, gortex rain jacket, and big USGA umbrella over my head, held low like a pup tent. Got to the course at about 7:30 AM and left at 8 PM when play was suspended for the second time.

I know this is a long shot, but anyone have a TV4 service manual?

I'd love it if someone could put up directions on how to get into the service menu, now that Dwin is no more...

To get into the advance menus hit - Mute, mute, enter,0,enter. Or it may be mute, mute, 0,enter,0. It's been a while since I have touched them.

didn't work on our TV4. Do I just hit the code while we're watching video, or does it need to be while the menu is up? We have the solarization issue, and it's driving us nuts!

That is how to get into the TV3. Solarization probably cant be cured from within the menu. Make sure all your fans are clean and working and some people have cured it by turning the lamp 180 degrees

Hello,
This is my first time posting on this forum, so please bear with me.
I have owned a dwin tv 3 since 2004, love it. I moved recently and was forced to leave the dvi d cable in the ceiling. Does anyone know where I can find another one for sale? Nothing on ebay right now...Or have one made?
Thanks

Do you by chance know if it's the same one used for the TV4? If so my neighbour may have an extra 25 footer. He can order them regardless...how many feet you looking for?

I'm looking for a TV3 cable.. shorter is ok. Can you help?

Talked to my neighbor, he can definitely get you the 25 footer that is used for the TV4. He thinks that it's the same wire used for the TV3 but isn't 100% certain. Send me a pic of the inputs on the projector and scaler box. Count the number of pins, etc...we can confirm on this end that its the same.

I can PM you his company's email address afterwards...

The cable I am looking for is a 13 Din, round on one end, and a regular dvi d on the other. The pattern on the round side is 3 rows of four, with one extra on the side opposite the push lock for a total of 13(hope that made sense). Please let me know if that's what your neighbors looks like and pm me, I would like to buy it if so. Thanks
