Picked up this set the other day, has an odd problem. The picture is quite
dim even with the brightness and contrast turned up all the way. I know the
CRT and associated circuits are fine because the OSD looks normal, also the
picture itself looks fine other than being very dim so there's obviously a
problem in the luminance circuit. I don't have a schematic and the chassis
looks rather complex, has anyone experienced this fault?

Check that the video processor has the proper supply voltage as a low
value there will obviously result in a dim video.
