Sony KV 1515 flashy picture

[damen]

Used to have to clean just about every trim pot control mounted on the circuit boards on those sets. AGC, AGC delay, B+, horizontal frequency, pin cushion, sub hue, ACC, video drives, and any others that I saw.

Its in Sams 2041-3
BUT this set may be one that had two different chassii. The audio
out was the big difference. So it may be best to look up
the chassis ##.
As far as problem goes can you put up a video of it ??

I cleaned the controls, still bad, it flashes between a normal picture and a very dim washed out one with reds and blues only, yea.. the green gun is still working. where and what do I look for chassis number on these?

thanks
