Question about RCA F27650 27" TV
White Horizontal line in middle of screen with bottom have of screen with good picture. Top half as a series of horizontal lines and no picture. Have replaced flyback transform before.
Look for bad capacitors in the vertical deflection amp, and in the pin
amp sections. This is common on most of these types of TV sets.
The caps tend to go high in ESR with age. It is best to use an ESR meter to find the bad caps. It will be a lot faster than workign out waveforms with a scope.
