Question about ASK Proxima InFocus Projector lamp for DP8300
The image on the screen is coloured with a yellow shade. Even if lamp is replaced with new one the yellow screen persists.
The light filter on the blue lcd is fried and needs to be replaced. it makes sure only blue light comes therough that lcd panel. when it's light is blocked from coming through, only the red and green lights can be seen, hence the yellowness (red light+green light=yellow light). it's common with lcd projectors. unfortunately, you can't buy that piece seperately. you need to buy the entire optical engine, which isn't cheap (almost $2000).

Actually, unnecessary to replace whole LCD module, find out which panel goes bad, then separately replace the bad panel, it will be ok.
the trouble is you should know how to align new panel when you install it.
