Another odd problem. One day it's normal, next day dim. It may come on dim at startup and will stay that way no matter how long it is left running. Same problem with different games, can't find a bad connection or joint, in either condition bright control on remote board and black level on flyback can both be varied to either extreme. But in the dim condition, adjusting both for proper black level leaves the picture barely visible. I've never seen a cap problem cause this kind of symptom, so haven't done a kit yet, but would be glad to if that might solve it. Any suggestions appreciated.Thanks.
 
cap

Check the caps in the left hand corner, that is after the power transformer. you will fine a cap that is out of value either in uf reading or esr reading.
