Might want to contact Mits and see what can be done about it now. Each part you would need would prob run you 150+. Theres plenty of videos on youtube showing how to replace the color wheel and DLP chip if needed out of warrenty.

I am definately going to call tomorrow. It has 2 months on the warranty, and it was shipped 3/4 received 3/13 so I'm good thankfully. I also noticed ghosting when I ordered a MMA fight (was pretty obvious) thought it went away when I adjusted the geometry but then I noticed it again when I was streaming TV. This is my first DLP so is that common or an issue as well? I looked up videos of the white dot videos on youtube but my dot is only white colored when the unit is off. Its like how a straight straw turns white when bent at an angle. I think it just got messed up in shipping because I have no idea how it got there but it isnt viewable when the unit is on unless im a foot or two away from the TV and then it looks greyish.

Thanks for your help, I just wanted to be sure about the issues before calling so I don't get blown off saying the TV fine and be SOL after my two month period.

The ghosting shouldn't be happening.. DLP has the fastest pixel movement of any tv out there. What you might of been seeing was internet lag from the signal since you mentioned you were watching streaming video.

Yeha I get what your saying now.. They should replace the screen. That's not anything normal.

I hope they don't say to you, "You got a refurbished (open box) tv, what do you expect?"

Take it from my wife that's worked in retail management the past 20+ years.. People that are nice usually get what they want unlike the people that go all off and blow up and start screaming at them.

Good luck!
post #963 of 1188
Would the ghosting be a color wheel issue as well? The first time I noticed and most apparent was from a PayPerView MMA sporting event tv hooked through a cable box. Second time was streaming on the PS3 but it was with an ethernet cord so there shouldnt have been any performance issues streaming at 15+ Mbps. And thanks for the tip, I've had good luck with retail issues hopefully this won't be any different. I wouldn't have minded the two defects on the screen but the ghosting is a big problem it irrates me like no other and was worried about the noise if it would cause future problems since the manufacturer warranty is so short.

Does anyone know a good a third party warranty? I was looking at squaretrade since I've had good experiances from them in the past but they do not cover refurbished models through their website only through their authorized dealers. So I could go through Tigerdirect and get one but they are asking for alot for a short period covered through squaretrade 1 year was around $120 and 2 year was around $175 neither of which overs the bulb. I called squaretrade to see if I could buy coverage through Amazon but they said those warranty's are only good on Amazon purchases (note no where on the Amazon listing does it say this). I wonder if I can go through Costco and pick up a 3 year warranty through them or if anyone else has any suggestions, thanks.
post #964 of 1188
That is one of the problem with refurbs. It's hard to find an extended warranty since the extended warranty services typically don't cover them.

First post here, hope to learn a lot and make many more. I recently got a 72842 82" (August 2012 manufacture date) tv in a trade along with 5 pairs of 3D glasses and she now sits proudly up in my bonus room. It's a huge upgrade from the 32" Samsung LCD that I used to have and my wife thinks I'm nuts for wanting such a large tv. I'm really enjoying it but I'm having trouble getting the picture set up. I have the brightness way up along with the contrast and temperature. I'm sure I'm setting myself up for problems sooner than later but I have no clue (or experience) getting the best possible picture for my lighting/environmental conditions. I love my tv, I just need to know how to get the best possible performance out of it.

you could get a professional come out and calibrate it for you but ive heard they are quite costly. or there are also dvd and bluray discs you can buy they will help you set it up your self which is what i did.

this is the one i ordered. http://www.sceniclabs.com/products/digital-video-essentials-hd-basics

if you do get one be sure to listen and watch the tutorial or else you will be confused. it took me a good 2 or 3 hours to complete it all. it takes about an hour by itself to watch the tutorial alone but it was worth it.
post #967 of 1188
Thanks for the link, I'll have to see if I can find that bluray locally. I'm a 100% disabled veteran and I can't work so having a professional coming out is out of the question as we just don't have the spare finances to do that. I understand that this is can be a very expensive hobby so I'll take all of the advice that I can get. If I can get something that I can understand and be able to see a noticeable difference I would love to set up our other 2 LCD displays. I'm all about a great looking picture biggrin.gif

The only warranty available for refurbished is Square Trade. I also know that if you used American Express they will double the two month warranty.

Every once in a while Square Trade has a $30-$40 off coupon and you can use that. I ended up getting one year warranty from then for $70 + tax. The good thing about them is you can get a complete refund within 30 days.

Until you have a calibration disc available, set your contrast between 40 and 50, and brightness around 30.

thank you for your service to our country.

just thought i would mention there are many different calibration discs out there and i only have experience with one.

here is a site that reviewed the top 10 best calibration discs in their opinion. http://tv-calibration-review.toptenreviews.com/

you can read over them if you like and see what you think.

How many people use the lamp's high-energy setting, "Bright" vs. standard? Do you feel guilty about using the extra electricity and does the lamp wear out faster?


I seem to use Bright in the daytime on some SD content.

I use the Bright and bright for both energy and video settings all the time and haven't had to replace the lamps yet on my 4 DLPs. I have solar panels on my roof so NO I don't feel guilty about the electricity and I think the picture is so much better. I had an older DLP professionally calibrated and he used the "Natural" setting. I could stand it for only a couple of days and had to have him re-calibrate using the bright setting and I was much happier.

I have been searching online for the best deals on the WD - 73642. I found one in Aberdeen, SD for $1399. Fargo, ND has one for the same price. Has anyone seen one in the Twin Cities area? Or where to look. Thanks.

Ebay has a new one for $1250. TigerDirect was selling refurbished ones for $850, but they are sold out of them at this time. Amazon occasionally has refurb or used ones at $850, you would have to check there and also get a 3 year warranty for another $100

Too bad it is not 65K
post #977 of 1188
I have the 73842 model and after having the light engine replaced 3x, I finally have a working TV. One thing that bothers me a bit, is that there is a clockwise tilt of the image. Its rotated/tilted about 1/4" to 1/2". I mentioned it to the technician and he didnt know how to level it perfectly.

I fixed the geometry in the service menu, but that will not fix the tilt. Are there any mechanical adjustments that can be done without taking the light engine out? I thought I read somewhere that there are a couple screws that can be turned to level the image out, but I do not see any reference to that in the service manual

Thanks

Ask this tv repair guy that has done how to's on you tube. http://www.youtube.com/watch?v=J4te3O0k1QM

Alot of great advice in this forum.

Here is my problem.
I have the Mitsubishi 82842. I love it!. HD picture is incredible. When I go to watch non-HD channels, the picture is very grainy/fuzzy (more than rt should). Other TV's in the house have no problems with the non-HD channels, I want to get the MLB Package, but the picture on these channels is just so bad. Any help would be appreciated.
post #980 of 1188
What is your source of video? If it is DirecTV, then the SD is pretty poor compared to Dish and most cable companies.

And how big are those other tvs? With an 82" HDTV any SD isn't going to look great or maybe even not acceptable. I have a 73742 and Dish as my primary video and some SD is very good, some just tolerable and some not watcheable, very channel dependent. With Netflix, Amazon and HULU, the SD on my set looks very good and of course the HD looks much better.

With Dish's better overall SD I still notice that many sports in SD don't look very good though most are tolerable.

I have regular cable television. My other tv is a 42 inch Samsung.
Is there anything that can be done about the SD quality?
I've also streamed a game on Roku....ok quality, not great.

Yeah SD is yuky on this set. Just checked it out and it looked pretty bad. I never watch SD. Glad theres a crap load of HD stations for everything I watch on ATT's UVerse.

If you cant stream MLB in HD from a computer.. wonder if theres another cable service that may have MLB in HD?

Just gota remember that on a screen this large a crappy signal will look much worse as the pixels are larger then on a smaller set. So crap in, crap out.

Other then all that most likely each station will look different with its signal and recording.. the MLB channels may look better then others in SD.

Also make sure your cable line since analog is newer and up to specs.. not crossing power cords, ext. If theres any splitters in the line there good quality and of high signal strength and theres no open ends that are not being used as can interfere. Like a 4 way with only 3 ends used. They sell caps that can be installed on the open ends to prevent noise in the signal.

Also want to point out something else.. when I recently added a power conditioner that also included cable inputs and I rerouted all my cable lines through it.. I noticed when I removed the cable connection from the wall that the connection threads on both ends where all dark and nasty looking. I cleaned them up real good with rubbing alcohol and q-tips and paper towel and shinned them up like new again. The threads are the ground connection to the cable line so obviously this would help to clean to keep a good strong signal. Also on the ends of the cable is a thin copper wire that sticks out. You should clean that as well. May even take some fine sandpaper and rub it to a shine (which I did not do). My old man used to take a knife and scrap clean the copper wire to get a better signal hehe.

As was said, the bigger the screen the more you notice differences in picture quality.

For instance, DVDs played on my 73" are just fine, as is the SD from the main streaming services. But SD from different sources is all over the place.

I run all my video sources through my Denon 2113ci AVR and have it massage the video a bit and upscale where necessary and most SD is fine. But most lives sports are just not all that good and even massaging the video isn't a great help.

SD is what it is and bigger screens don't help that unfortunately.

This is very much source dependent. It also helps if you have first class scaling and deinterlacing. If the source sucks it will suck even more on a big display. Lots of SD look quite nice on my 92840.. I have a Radiance but a PC with a first class GPU can do pretty well.

OTA is often the best looking TV source whether SD or HD.. I am moving toward JRiver Media Center fairly soon for live OTA and Cable TV. MadVR can do wonders to a reasonably go SD source even on a big display.

Ok so I ordered a roll of Duvatyne tape, took off the screen on my WD73642, and pretty much covered every piece of reflective material inside the television. I used over the half the roll to cover for it. I covered the silver support bar at the top, the silver support bar at the bottom, the silver and glossy black material around the projector, the white pieces that hold the mirror, etc. Unless there's something hidden away somewhere or something that wasn't obvious, I pretty much covered every reflective thing inside the television with duvatyne. End result: no change. I still see the halos and reflections at the top part of the screen when watching letterbox movies or when there's a lot of contrast in that area.

Any ideas what else inside the television could be causing the reflections? Is it possible that it isn't simply an object reflecting the light and an actual issue somewhere between the lamp and projector? I'm prepared to take the screen off again and cover up something else if anyone has any ideas on what I may have missed... I took my time looking through everything around the top area of the TV and I simply couldn't spot anything reflective that I hadn't already covered.
post #986 of 1188
Any chance of what your seeing is not some light reflecting off something in the room and bouching off the back mirror in the DLP? Even turning off all the lights in the room you still see it? Light from the screen reflecting from something in the room back into the screen mirror? That's gota suck.
Might be something on the lense as well.. I'd contact a professional repairman and pick his brain.
post #987 of 1188
I'd ask this guy.. he seems like he would have your answer.

post #988 of 1188
It actually also happens on my WD65738 to a lesser degree that's upstairs in a different room with different lighting. Others on this thread have complained of the same thing and recommended using duvatyne on the interior but noone's actually fixed it yet as far as I know.
post #989 of 1188
Just thinking out loud.. but wonder if its some manufacture problem with the lamp housing where its not making a perfect seal on the inside and light from the lamp is seeping into the tv? Just thinking out loud and throwing ideas out there.

Only way to know forsure is to prob remove the back from the tv and turn it on. I believe theres some safety switch that would need to be pressed so the tv would think the back is on..

That seems to be a reasonable guess. My 73642 doesn't have the issue which makes me think that it isn't the reflective surfaces in the set causing the issue, but more likely an assembly/shipping issue where something is getting slightly 'looser' or some such allowing for light escaping. If it was the reflective surfaces I would think it would affect all sets and not just some.
