Question about Projection Televisions

Strange colors and shadowing and then went black.

Hi, thanks for your solution. I tried to find the Mainboard part for my tv, however I found there were lots of variations. Could you tell me exactly what part I need to order to fix my tv. Replacing the mainboard will fix the black screen on my tv?? My tv was Sony KP46WT510. Thanks again, Lisa

No picture strange sound


Hi , I try to share my experience about no picture strange sound in DLP models,
If that sound from behind TV like friction sound it mostly from the color wheel.
Open rear cover, switch on your TV and listen , it it from angine not from speaker, that the color wheel problem. replace it.

Samsung DLP TV shows green color where color should be black


This could be your video board going bad where your input cables are connected --OR-- the color wheel going bad. Hard to tell without a photo or reference though. Try swapping the cables first... and listen for any winding or whirring sounds.

Color wheel has broken and needs replacing


Hi Steve.
replacing the colour wheel is possible, you will need to strip out the light engine from the TV, and open it up to gain access to the colour wheel assembly. A replacement colour wheel is about £250 from sagem, although you can buy an equivalent wheel from the US for about £80.
Check on the avforums site in the RPTV section, there are a lot of helpful people who have replaced their colour wheels successfully. 
Cheers

TV projects a pink/green shadow


Logically proceed one source at a time = disconnect all,
then hook-up one at a time or hook-up seperately.FYI, the
RF coax , composite and s-video inputs all share the same
circuitry, whereas component is a whole seperate video
processing circuit, with another difference between 480P and
1080 I . Sounds like you have a 1080 I problem, which might
be a little sister board..............................T.

Let me know..............Thanks.
