Toshiba 50HM66, 56HM66 Discussion - Page 39

Well, another update...

I put the lamp cover door back on, making sure that it made good and consistent contact with the safety switch (tried wiggling/tapping it after installation to see if I could make the yellow LED come on (on the front of the TV). When I was satisfied, I turned the TV on. It was on for about 5 hours with not one problem.

I monitored the temperature sensors for the first hour or so.
Time Temp1 Temp2
start 32 34
30 mins 44 56
60 mins 45 58

Never saw them get higher than this.

At this point I'm hopeful, that the cleaning (and maybe the mucking around with the safety switch?) has resolved my problem.
Fingers are crossed.

So far, hasn't cost me anything except some time. And I've learned a bunch of things too!!

...Dano

It was the safety switch.

I'd say a combination as you surmise as well. Good news for sure. I truly love my set, and no reason to switch since I can make this more than acceptable set go for quite along time. Parts are readily available if needed. The cost of the Lamp is $105 now + shipping. More than reasonable. So I have a spare lamp now. Spare light engine to boot, so I'm good for awhile.

Just got a FREE 56HM66 Toshiba DLP. Awesome looking set, much better than my 10 yr old 36 old school tv. Problem:

1) The TV sound stopped working after day.

Called the original owner.. he said it did that about a year ago for him but hasn't done it since.

Hooked up some old computer speakers to it and I have sound with my beautiful picture but a pain in the .... to change the volume now. Tried owners manual troubleshooting.. says to mess with the audio settings.. Followed that.. no change. Been 2 days now without sound on this good looking tv.

Anyone have any ideas? Need more info? lemme know what I can do to fix this... or who to call for help.

Thanks in advance.

Connect to an AVR that has a remote and be done with it. For free, you really can't complain. That even beats my deal of $50 that I got my 56HM66 for. Congrats.

Hello everyone and first time poster here. First of all I just want to say great forums and have learned a few things from members posts. Now to my question I have and it has to do with my Toshiba 50HM66. I bought it 8-14-06 and after the first month the lamp blew up. Now almost 4 years later and 4 lamps which I just replaced today. After replacing the lamp I noticed that the picture was not as clear. Could this be that the mirror/mirrors have dust on it/them. I cleaned the back out the best I could and used a vacuum and canned air as well.

Now after doing this could I have blown dust all through out the TV and would it of gotten on the mirror/mirrors. I also found info on how to get into the amount of time on a lamp and so on. I then pressed 9 while in their and came across this. I took a pic with my phone so it's ok quality. But does this mean anything or is this normal. Also what is the amount of time others have on their TV for being on. I found out that I'm at 11,000 plus. And with there being 8766 hours in a year I'm thinking 4 lamps to have gone are a lot.


And if I'm just rambling on not making any sense please bare with me. I was hurt at work real bad years ago and on tons of pain meds.

So I do apologize if this post made no sense.

Picture looks clear to me.

It's going to be hard to judge the picture by me posting one. It looks hazy while watching it and white letters have a shadow effect. That's why I'm wondering if the mirror can get dusty and cause it to have a not so clear picture. I've also looked through here and did a search on cleaning a mirror. Unless I'm blind which could be the case I found nothing. Can it be done by someone who has a technical back ground. Or is this something that should be done by a trained service tech.

Also the lamp I bought was from Advanced Lamps and got it for $100. It's the one they make and supposedly fixed unlike the Toshiba lamps. One more thing can a DLP be calibrated by again someone like me. I was also wondering if firm ware ever has to be updated or any other update for that matter.

Sorry for so many questions, just finding my away around here for the answers as the days go by.

Thank you.

Yes, the mirror can get dusty as can the light tunnel get dust blown into it by canned air, and also there is a single lens that needs to be cleaned. Remove the front screen/frame to gain access to the mirror and lens. Use SPRAYWAY GLASS CLEANER (found at most any hardware/supermarket) and remember a little goes a long way. Look for the topic 'Don't dump your CRT' for cleaning methods of rear projection TV's.

I got my lamp from Advanced Lamps also (the one with 4 screens around the lamp cover) and so far no problem. Infact I ordered a second (spare) lamp from them.

Calibration can be done to a limited point. Get a copy of Digital Video Essentials on Blu-ray to calibrate the TV. No calibration is as good as a pro calibration but those costs about $400. Still well worth it.

Not aware of any FW available, and not sure how it would be installed on these sets.

Did you maybe touch the lens of the lamp? That is what I think might have happened causing a blurry picture but even that is a stretch.

I have the 56HM66 and I love it.

Thanks for the help. As for the lamp that would be the same one I got and for a price that can't be beat. I hope it's much better then the Toshiba lamps I have had. I assume it will be and by looking at it the quality looks to be much better. As for the lamp it's self it wasn't touched. I actually take a bunch of precautions before I even open the box. One is a bandanna across my mouth and the others is surgical gloves.

I use a bandanna because I have no 3M face mask. But I do that just in case I sneeze or some spit jumps out of my mouth. I don't want anything getting on the lens. As you know it can be ruined by everything it comes in contact with. Gloves are used just in case a finger slips and smudges the lens.

Any way I'm going to pull the screen cover off and clean it. I'm hoping it helps because every show from SD to HD look awful. And I can only assume it's because I'm an idiot for cleaning the TV the way I did. Guess you live and learn. But if cleaning the screen and mirror don't work could the light engine be going bad. Also where the light goes there is a lens on the left side. I was wondering does that need to be cleaned or is that a no touch leave hands off lens.

Again thanks for the help.

If you need a light engine, these are a helluvalot less expensive than a new TV. I bought from here. Love 'em. Here is your Light Engine:

I just got a 50HM67 given to me. nice and free. but i wasnt so lucky. it was missing the lamp.

AND... the Seine board is bad. the TV will blink the lamp light 3 times, pause, 3 times over and over again. I just so happened to have another of the SAME Tvs i was working on for another customer at the shop, so i borrowed the lamp and its door for it. Just so happens, i got both TVs from that same customer, gave me one that he didnt care about as long as we fixed his other one.

Same issue. diagnostic LED on the Seine board goes from green to orange which isnt normal. the LED should come on green and stay green. This is a physical LED on the board itself, near the hidden SD card slot.

The one that i fixed had a defective power supply. the ready light would turn green, soon as you pressed power, nothing would happen and the Seine would reboot again. and go back to the green ready light.

Anyway....

I stuck the whole engine from that TV into the other TV that i fixed and it worked beautifully, so that rules out the engine and ballast, plus switches/sensors.

all voltages are on target, so the only thing left is the Seine board is toast :-(

hey splicer? you must be local to me. I seen channel 9 WCPO on your set. hehe. cincy area. im in hamilton

Send it in to be repaired. Here you go:

http://www.moduslinkptstvboards.com/...54-P24345.aspx

ouch thats high. might have to pass on that one.

I used to work for a repair shop that used PTS. they are ok, but theres been a few bad times with them. I have no personal experience with PTS though.

I bought my lite engine from them back in March and all is well (knock on wood ) as can be. Besides, you just need to call them and get a quote on a rebuild since they don't seem to have any in stock. Either way far far less expensive than buying a new set.

Can anyone post the settings they have in their service menu. Like a dip I messed around with them thinking I knew something and screwed things up. The list I'm asking for looks like this. Obviously that is part of the list but is what I need. And I assume this is where you would calibrate your TV. I made the mistake of not writing down everything before doing it. Thanks and have a good weekend.

And this would be for a 50HM66.

Good luck. All TVs are different and the settings are unique to each individual set. Last time I tried giving the settings (for another soul that messed around in the SM without writing the original values down) it (as I tried telling the person beforehand) was a waste of both of ours time.

I figured and I can only blame my self for not thinking. But the TV needs a new light engine anyway. And if I'm correct when replaced those settings will be back to original. If not I'll just have to contact Toshiba and see what they say. Either way the light engine is bad and replacing it. The store I bought it from 4 years ago is giving it to me at cost. So for a brand new light engine I'm spending under $300.

This time though all should last me a lot longer. I know more about the TV since coming here then in the years of having it. I also need to find a bezel since I broke the 3 tabs when removing it. Another hard lesson learned. The sad thing is that I build and repair PC's for a living out of my home. I should know better now to take my time. Here I was like a fool jacked up on Red Bull just wanting to get things done. Also if anyone comes across a web site that has my grey bezel for a 50HM66 Cinema Series please post it here. I'm looking and will continue to do so. Problem is so far every site site has said not available. If nothing I can super glue them back together which should be fine.

I would appreciate it if your browsing and happen to come across one.

Thanks.

$300.00!? No, no, no...Here is your LE rebuilt (but out of stock, BUT yours can be rebuilt) for under $200.00!

http://www.moduslinkptstvboards.com/75002047-P6055.aspx

Also, as I said on the other site, for the lamp get it at the place I told you. This is the lamp AND the housing included in the price.

As for a new bezel, I think you are out of luck short of directly from Toshiba. But I would'nt sweat it too much. The screws will hold it in place just fine, or at least they should.

Finally, to each his own. I know you like the 70 Z28, but I was never a fan of that body style (nose and tail light section. I had a 70 Firebird that I feel looked 3x as bad as the Z28, and with the 400, quad 4, turbo 400, that bird would shite and get it!

Wasn't thinking when I typed that and $300 is money wasted. As for the lamp I believe we get them from the same place. Advanced Lamps is where I got mine from for a little over a $100.

Now to the cars. I like that year Firebird as well and my buddy has one. It's an emerald green or something like that but very nice. But I look at it this way, if it's in the GM family I like it. I don't like Dodge/Chrysler or Ford. I take that back the only Ford I like is a 67 Shelby GT500. My father owns one among other hot rods. I'm a car freak and like speed and could talk hours about cars.

Anyway thanks for all the help you've given I do appreciate it.

One more thing does that place for the LE usually have them in stock. I'd rather order one up then have to send mine in.

Couldn't say what they have in stock as I only need parts for my 56hm66 in which they have ample LE's in stock for it. But I just bought a rebuilt one back in March this year and I have my old LE for future parts if I need it for any reason. The light tunnel is the only thing wrong with the other LE and if motivated I could probably repair it myself. If I were you I would send it in no problem. Helluvalot cheaper than a new TV of equal performance.

I here ya. I also fixed what I screwed up in the service menu. Now I thought unplugging the TV would just do it but nope. From the info I was given is that anything plugged in must be unplugged. Wait two minutes then plug everything in and turn on. Now the peoples heads don't loo like oranges and I'm a little happier.

As for the Sprayway still no luck. It's like no one in my state carries the stuff. You mentioned Home Depot and they did a search and came up with nothing. You'd figure that they all would have that item on their shelves. Now I did make a post asking about the Klear Screen I use. It says on the back that it can be used on precision optics. I assume it would be fine on the lens on the Toshiba.

Opinions welcome.

Here is what I have and use to clean screens with.

http://www.klearscreen.com/detail.aspx?ID=10

I'd just order it online then.

http://www.amazon.com/Sprayway-SW50-.../dp/B000FMK1NY

Apparently that's my only option since not one store here has it. But like I asked above will that Klear Screen work as well. Might not be suitable for the mirror but optics it says yes. Since I'm not expert here on doing this stuff I'm curious if it's ok to use.

Thanks again.

Never heard of the stuff before you brought it up man. If it is a liquid, I would put some on a microfiber towl first and then clean the lens. You could probably get away without doing the mirror, though I still recommend doing it since you are in there already. I only know that Sprayway is tried and true and won't harm the first surface mirror.

Just to make sure we are on the same page this is what it looks like. I ask because the link to Amazon shows a different picture.

http://www.homedepot.com/h_d1/N-5yc1...atalogId=10053

And Home Depot does have it. It was in the back on display and the young kid is an idiot. Just need to be sure before I buy.

Thank again.

Yes, that is it. The only difference is the cap. But they sell it individually, don't they? I know I can (and do ) buy it at Sams Club (been a member for years) 4 for like 7 bucks I think. No more than $8 tho, I'm sure of that.

*EDIT* Of course, if you are sending the LE in to be refurb'd you don't need to clean the lens. The LE will come back spotless, including the lens, so all you really need to clean is the mirror.

I got it and was $3.00 so not bad at all. I hope this helps but when I took off the front last time not much dust was in there. It was the same amount that you would have on a coffee table every week. I wouldn't think that amount would cause issues. But you say it does and we shall see. Not that I doubt you either.

Thanks.

1/07/07 got the 55hm66, pic is getting quite dim. Ordered new lamp and hope when I install it, it will look amazing again !!

It will...
