    The reason the DLP chip fails is it overheats.
    It’s got a 180W lamp shining on it, and when the gray heatsink tape dries out, the DLP cooks.
    You need to scrape the gray heatsink tape off the heatsink with your fingernail, wipe and clean the heatsink and DLP surfaces with 91% rubbing alchohol. Apply quality heatsink compound such as Aavid Thermalcote I to both heatsink and DLP surfaces. Do not cinch down the heatsink screws. Back them off a little so the springs do their job and allow the heatsink to float and lay flat against the DLP.

    I think following the instructions above without using new heatsink grease will result in white dot failure again. Mitsubishi cheaped out on the heatsink grease, and all these sets are failing.

    A couple of technical errors.

    Dissipative gloves, rather than plastic gloves, are recommended. Plastic gloves build electrostatic charge. The gloves shown are the typical black dissipative gloves.

    Step 15. I believe you meant to write “sensitive to electrostatic discharge” not antistatic. :)

    Just ordered a replacement board. These instructions will make the swap very easy. 10-Q
