If one color is missing from the video, on all sources as well as the OSD, is is easy to determine if the problem is the Main Board or a defective LED/Driver. Enter the service menu and select CCA. Turn CCA OFF. Go to Sensor Status and select it. The bottom row of numbers indicates the LED Driver's current draw for each LED. Of one of the LED is drawing 0 current, either the LED or the driver is defective. Verify by swapping the LED connector from the suspected LED with a known good one. If all of the LED's are drawing good current, the problem is in the main board.
not missing any colors. i have a pink shadow that i can see through on the left hand side. also a pink 2 inch horizontal stripe across the top
i did that test mike. all the sensors are reading 244. i also did dmd test. all colors show up however on the white one i can see the purple see through lines and shadows. when you said bad board were you refering to the dmd board or the main board. my antennea input also doesnt work
this could mean a bad led driver board.....swap out with known good and see what happens..

Hi..it is the DMD board (digital mirror display) but IF it can be repaired it would cost around $300.00 to repair and $970.00 to replace. I would tighten the screws that hold the mirror to the board first. All four of them. Sometimes if the screws are loose, you will get the vert. lines too.

Its the DLP IC chip itself that is bad. The DMD board is where the chip resides but if you order a board, it will come without the chip. Its not cheap and the replacement is tricky because the DMD board must be removed and then an alignment of picture centering will be necessary.

i replaced the dmd chip and it resolved the white dot issues but not the what is now the purple see through shadow and purple see through horizontal 2 inch wide lines. went to dmd tests and all colors work but the white screen has the shadows and lines. looked at the sensor status and all are reading around 214. the purple haze has some yellow around the edges.
