hi there!

 

my first post here!

 

i recently got this for cheap, but it has these colours on the screen. the guy i got it from said it needs a new colour wheel. but i dunno. dispite the strange colours, the picture is fantastic, sharp and blacks are blacks and whites are bright white. (except when there green or pink hahaha) what do you guys think?

 



 

its a Toshiba 72" 72CM9UA‏, if you need more info, let me know.

i just tried plugging in a different TV in using the same hdmi cable and the problem disapeared (with the new tv) indicating the problem is AFTER the hdmi cable i,e the tv is malfunctioning and not the cable, video card of my computer or the video codecs of my media player. any experts on dlp? or anyone know where to point me?

 

cheers!

Difficult to narrow down within the tv. How does the on-screen menu look? If the menu looks good, I would assume that the light engine is good, and the problem is in the video processor board (whatever it's called). If the menu is also bad, then the problem is likely within the light engine. In that case, look at replacing the whole light engine, as I'm not sure the individual boards within it are serviceable.

This is a good tip, and definitely worth trying. Hopefully the OP reads this and at least attempts it. The two chips you mention are the "driver/processing" chips for the actual DMD device. I can see how their not functioning properly could produce the problem shown in the pics.
