Mitsubishi WD73831 color issues

Post by orleandean »

I bought this beauty in Dec. 06. Have had zero problems with it till last week. Had been noticing that the broad view's were be coming more pixulated. Figured it was the bulb dimming or something like that. Ordered a new bulb, replaced it, and 8 minutes later it blew up. Put old bulb back in everything back to sub-normal. Then it started---TV would run fine for an hour or so, then the color would start flickering, and eventuall go to brown/black and white. If I turn the set off and let it go through it's shutdown proceedure, and turn it back on as soon as the lamp light stop's blinking, it will come back on and be normal for about a half an hour. I'm at my wit's end--any idea's out there?

Contact Mitsubishi - it's probably the light engine.:

Light engines are not repaired to component level so the service industry has no answer...

Gotcha--Has the service industry, and Mits gotten better than some of the older post's have indicated?

Orleandean: if u have seen/read the nightmare posts about the light engine and warranty issues you'll see that i have/had lots to say about it. So, after all the knock-down, dragged out fighting...mits replaced my tv with a brand new one. i've had it for maybe 6 months now with lots of watch time on it (wife is home all day!). I had it calibrated, along with an audio calibration for my denon audyssey and i will honestly say that it has been awesome. i really hope that mitsu has learned from this. hope i've been of some help, somewhere along the way.. :?:

not sure it will help..but it certainly can't hurt! I have no problem with it at all. Might have more of an impact if you refer them to all of the posts that are in that forum.

Anyone in particular I should talk to?
Turned TV on at 10AM eastern, and picture is still perfect at 3PM.
