Have a P447 k7000 series that has all but the 3 (C4,5,6) caps not offered in bobs kit replaced.
Goes from perfect to black in about 20 seconds after about 20 min.
Had problem before and after cap install
so looked it over good a couple questionable joints re-flowed still goes black.
So where do I start to troubleshoot?

start with R21-29?
2N3904?
Will checking voltage at the brightness pot before and after the problem tell me anything?
any help is appreciated
