>>The Official Mitsubishi 1080p DLP Owners Thread<< - Page 180

We have a 62628 as well at home and I noticed the screen has some sort of geometry distortion. I guess this is normal for this type of tv, but I also noticed another problem: something that looks like the picture/brightness flickering when you look close. Anyone know what causes this?

I found this 2006 model on Craigslist and was hoping that someone might be able to help diagnose its problem -- what needs to be replaced and how much it would cost.

Thanks!

I had the stuck white pixels from with the DMD chip on my WD-65734. It got replaced by a local service provider and the pixel problem is now gone. However, afterwards, I noticed a shadow smudge located in the upper center of my screen that is visible when the image has a light background. The image is also rotated 1-2 degrees to counter-clockwise.

I'm certain the shadows weren't there prior to the DMD replacement and there may have been some of the rotation/geometry problem but not as pronounced as it is now. Neither the service provider nor the manufacturer will take responsibility for these problems introduced during the installation process because they consider it a "light engine problem" which means full replacement, even though it probably doesn't have to go that far.

For the shadows, I suspect dust got on the chip or inside the light engine when we dusted the fans.

I'm pretty technical and also watched the tech install the DMD chip 3 times already (first time it didn't work, second was reinstall of the old chip to confirm tv was working, third was reinstall of the new chip that worked this time) so I'm pretty confident I can pull out the light engine to check for dust on the chip.

But, if it is not directly on the chip, where else should I look? I've seen some other posts where people disassemble the light engine more to clean stuff inside. I did check inside the box behind the screen but the mirror looks pretty clean and anything there seems to cast a sharp edge shadow so given how unfocused the shadows are, I suspect they are farther back in the light optics chain.

For the rotation/geometry, I tried the service menu recalibration process, but the top right corner is too far outside the bezel to even bring the cross back onto the screen. Also there is no rotation correction. Any tips on how to adjust this?


Pictures of the problems:

Shadow smudge with less image correction. The background is pure white, the blue gradient is an artifact of the picture-taking. There are two smudges, one on the bottom and a separate one at the top. Each is about 3x3" in size.


Smudges with more image processing to make them more visible.


Picture of the whole image. There is some distortion from the camera lens but you can see the rotation and geometry problem relative to the TV's bezel.

Not sure if this is a warning of an impending issues, or if the wife didn't turn it off properly, but my 73835 started acting up a bit last night.

I would tuen it on, it would start going, the blue accent lamps would start up and then it would blank, all the lights would go off and then it would start the green flashing light. It did this to me for a couple of tries, until I hit the power button on the TV and then pulled the power cord for about 15 secs.

After this the TV went on as expected and stayed on as expected. Let's hope it stays that way.

Has anyone else seen this happen with their unit and, if so, what did it turn out being?

Seggers

Being slow that I am, I fianlly got up close with the TV when it went dark. Turns out it was the lamp light that was flashing. Pulling the power gets it back, but it looks like I have a bulb to buy pretty soon....

Did you recently replace the lamp with a non Mitsubishi part?

no
it has been in a few months before this happened. put in a old dim lamp for kicks still the same.
called another TV shop today he said it's was a board problem, $350-400 to fix it. then tried to talk me out of fixing it., just buy a new set he said. thought it over for 30 min and called him back ...they come out to pick up this monster Friday.
this set just does things i can't buy p-i-p & the ota dvr would be missed a lot.
none of the new TV's have p-i-p that i looked at with a 60'' tv it is very useful. this one shows 2 31'' pictures.
thanks for the reply

I just purchased a refurbished Mitsubishi WD-73642 for about $850+tax. It comes with a 90 day warranty from the manufacturer. SquareTrade is offering me a two year warranty for $165. It is working fine now, do you think it would be smart to buy the warranty or are the sets pretty reliable?
Edited by MitchFlorida - 3/8/13 at 12:52pm

did you call them ?1.877.WARRANTY
would and ask about a longer warranty. bought 4 and 5 years on my 2 Mitsubishi tv's from SquareTrade they took care of me well. but it's a crap shoot. 5 years are the best value imho.
one house call $300+. as you can see from my above posts can be $800. lol
myself really like these tv's
good luck with what ever you choose

Because it is refurbished, Square Trade will only extend my 90-day warranty by two years maximum for $165. Are you saying that it it s good investment?

How many repairs did your DLPs need? How much did it save you in costs, or was it just for peace of mind?

the Mitsubishi WD-62827 got 3 calls in 5 years #1 for a lamp. new lamps were $175 to 230 back then so it paid off easy.
the 73 c10 got a light engine after 8 months $700+ covered under MFG warranty.. now have 2 years left on Square Trade warranty.that 's not been used yet.
for you it's a gamble pay $165 now or twice to 4 times that if you need a call, plus if another is needed in < 2 years.
would buy it myself.
in 35 years of buying stuff I'm ahead a few bucks. don't buy them for washers/dryers freezers fridges. but TV's all of the time unless it was in a bedroom that's seldom used.
good luck

What do people here use to power their Mitsubishi DLPs? A surge protector for about $10 or a UPS for about $50 or nothing?

use a surge protector on them.
the WD-62827 is also on a power strip that's turned off when not in use since i got a kill a watt and found it uses 35-45 watts when not in use.

you buy the Square Trade warranty or not ?

There were limited options on the refurbished warranty. I got a one-year term from Square Trade for $75, so I am covered for the first 16 months. Square Trade doesn't cover the lamps, but I think that is overblown anyway. I can get a replacement bulb from Osram (I think they make the oem bulbs) for only $60, and a new bulb + housing for $90. i have read that most problems come in the first year. I would like to get 10 years usage from this set, I don't know if that is realistic. My last Sony rear view projector was 12 years old and going strong, but made obsolete by new technology.

got it back on the 13th tested it over the weekend and it's all good. very happy with it.
picture is nice as when new.
this was a first for having out of warranty repair for me here in Las Vegas so i called the company that has done warranty work
the past 7 years and they did not diagnose the problem in 2 house calls they charged me $75 but told me the
Light Engine was bad on the second call so had it rebuilt @ a total with shipping of $313 plus hours of my labor taking the
Light Engine in and out. will not trash that company.
but will talk about the company that fixed it.
arrived on time to pick up the 176 lb TV Thursday back fixed on the following Wednesday.
fixed right the first time. they will be getting all my out of warranty work now. they Do Not do any extended warranty service.

Discount TV 702-458-0585 ask for John
work done
ballast board - repaired circuits
replaced lamp - worked but was cracked
replaced lamp cover door- warped
cleaned optic's

total bill $340

being a smoker not good for this type of TV having done mirror cleaning myself bet he found lot's of build up in there.
in the end now have the Light Engine rebuilt not needed now but it's good to go for the future now.
hoping to get more years out of this TV.

You paid $340 for a good repair and $388 for a bad repair? Total $728 plus hours putting in an unneeded part? I would be angry about that. I would dispute the $75 charge with the credit card company.

these are repairable TV's as long as parts are available. and each model seems to have some different weakness.hope you enjoy yours for 10 years or more.
this 62827 cost me $5,000 new 7 years ago need to get 20 years out of it at this point don't know if i have 13 years left myself lol.
choose this TV over a $10,000 60'' plasma still happy about that....... oh 2006 those were different times.

true too old to get mad/angry about $75. the guy has been here a few times over the past 7 years did the best he knew to do.
heck i'm happy that did not let them do the light engine @ $770 and it still not work.
could have gave up and bought a new tv for $1000- 2,000 and not been as happy with it due to less features (pip. OTA Dvr)
saving up my mad/angry mode for when i soon do my taxes, now that will make me mad/angry lol

I had a Mitsu 92840 and a Mitsu 73835 calibrated by Chad Billheimer ('Chad B') at the end of last month. The 73835 took the longest to calibrate due to the placement of the menus over test patterns. Chad took his time with it and got some great results with both sets. Grayscale and color gamut are VASTLY improved on both, black levels and gamma look better to me, and I am enjoying the sets a lot more.

Because light output was low on the calibrated 92840, Chad created another Daytime\Dynamic setting that can leave turned on for the wife's television viewing, then I switch it back to the movie setting for discs. I just watched the re-mastered "Lawrence of Arabia" on this and it looks great.

Chad did a great job and spent time answering questions about the sets, my audio setup, game systems, etc. I will definitely have him back. I’m in Chicago, he seems to get out here frequently.
