I recently replaced the DLP chip to take care of the white/black dead pixel issue, and it worked perfectly! However, now, the picture is blurry, although it's definitely not missing any pixels. The picture is definitely blurry all around, but it is more pronounced in the lower right area. It's still watchable, but it's like watching SDTV, not HDTV. The input is 1080p from a PlayStation 4 through HDMI. During the repair, I scraped off the old thermal tape on the back of the aluminum heatsink and put on some Arctic Silver 5 thermal paste. I also replaced the lamp with a Philips lamp - figured I would do it while I was in there. The chip I used is a 4719-001997 that listed this TV model as a compatible unit. The lamp used was a 915P061010. Please advise? Is something dirty within the TV, or could I have mis-aligned something?
Sounds like a misalignment problem. the lens has a specific optical plane the DLP chip must be positioned at in order to provide the proper focus on the screen. Try repositioning the board or adjusting the lens to clear up the fuzzy picture. Regards.

Not sure...but the inputs (and related circuitry) on Mits are notorious for failing due to weak components. Test to be sure that all inputs are dead? If so...this may not be an easy fix.

It will cost you probably in the area of $700.00 to replace the Light Engine. I don't think it would be a good idea to repair it. DLP sets have been out of production a few years now due to high failure rates of the light engines for all makes and models and the consumer cost for the lamp.

You have a bad light engine. It is available at encompassparts.com for retail price of $749.10. Call 1-800-638-3328. Consumer not in business could be higher price.
Likely you either forgot to reattach your color wheel ribbon connector, or have it on upside down. It's the tiny ribbon cable behind your circuit board that will come off as you pull the board away from the DLP chip.
