Hi,


I actually have a Barco RetroGraphics 800 big screen, but it has almost all the same boards as the BG 800. Anyway, any ideas on what to look for to solve the problem of jitter and video noise only on the green tube? I swapped the small RGB board by the CRT's with no change....Any other ideas? Thanks....Steve.

Someone has had to have experienced this...The picture is good, but the green gitters slightly and causes it to look slightly out of focus....there is also some slight noise or static in the green tube. It apears to be a cap somewhere, but question is, what board? Anyone that can give me a little direction on where to look, that would be great....Thanks....Steve...


PS - the projector only has 1435hrs, but has been sitting for many years....Thanks...Steve.

Steve,


See here:

This thread is somwhat about the same issue. I have a very noisy Blue I have come to notice as well. Looks like a cap but not sure where it might reside.
