Like several of the AVS forum members that has posted earlier in this thread, my 65HM167 started having "stuck pixel" problems. My 65HM167 is now 5 years old with about 10,000 hours of use. About 3 weeks ago it started with one pixel stuck on (creating a white pixel). Within two weeks the number of stuck pixels had increased to 6. I went ahead and ordered a replacement DLP chip for $159 from shopjimmy.com (Link for the correct DLP chip is HERE
). The new DLP chip was shipped the same day I placed the online order and they used 2-day UPS shipping. Note that the replacement DLP chip they are selling has a different part number than the original one in the TV, but it looks identical and it works without any issues.
FYI - You must first remove a plastic panel/cover that runs virtually all the way across the lower rear of the TV cabinet with openings for the Input/output panel and the lamp access door. This cover is held in place by several screws which should all be removed first and the bottom of the cover has several snaps/clips that can be released by inserting a flat blade screw driver in the slots and pulling the cover away of the TV cabinet (start at one end and release each clip one at a time as you work your way toward the other end of the cover). After the cover is removed from the TV then remove the lamp cover that is held in place by one screw. You should then remove the two screws that hold the light engine in place then unplug several cable connectors and release a the cable retaining clips that hold several cables that run from the light engine assembly to the electronics chassis that is located just to the left of the light engine (as viewed from the rear of the TV). If you download the Toshiba service manual for this TV then go to page 10 and follow the instructions for "Light Engine Replacement" (to download the service manual for free, click on the link for "get manual" that is located just below the document preview image on THIS WEB PAGE
). I took my time to carefully remove the light engine assembly from the rear of the TV then to open the metal box and remove the PC board where the DLP chip is mounted. It took me just under 2 hours total from start to finish, from lifting the TV off of its stand to putting it back after the repair.
There is a good two part youtube video (Part 1 is HERE
and Part 2 is HERE
) that shows how to replace the DLP chip once the light engine chassis has been removed from the projector. I also used a brush and a vacuum to remove all the accumulated dust I could before replacing the DLP chip. I also dusted off the projection lens that is part of the assembly.Edited by Ron Jones - 6/23/12 at 6:05pm
