SOURCE: I need the shematics to install A DMD chip in my Mitsubishi Model WD-C657
When you take off the back cover you are pretty much looking at the chip. Right in front of you in the middle of the light engine is a little fan.
Remove the fan and you will see a big metal heat sink / shield. remove the sheild and you will see a circuit board. in the middle of the board is the dmd chip.
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.
