My faithful Sony 1270 is now projecting a picture that is slightly darker on the right half. The screen is divided almost perfectly - it is as if the right side is set to a lower brightness.


It's the same in setup, so it's not the feed. Any ideas?


Thanks much,

Garry

I can't say that I've seen that on a 1270 before. Problem is, this could be about anywhere in the set.

-H board

-CPU board

-almost any of the video boards in the set that pass the video signal.


I've got a working test chassis here that I can test your boards in, but without having seen this issue, you'd more or less have to pull about 30% of the boards out to narrow it down. Mind you, shipping several boards won't be that expensive.

I had this same type of problem but it was a lighter screen on the bottom half of the screen with a heavy green push on dark scenes.

No one could figure what the problem was, but one night the projector was working prefect until I picked up a magazine off the floor and the problem reappeared and what I realized was the magazine was blocking the leds of my pv 900 amp..


Could your problem be as simple as this?
