Received a 19K7000 for repair. Wasn't DOA - but was close. Heater on, no picture at all. Has been capped in the last few years, so I have not yet touched them. Has a hack repair job in the power supply (bad bridges, burns, lifted traces, tarnished pads). Corrected all that I could find.
Upon power up, we have picture, but out of focus. Noted that you can adjust the focus, but it only changes things, it never actually gets anywhere close to being able to focus. It's really, REALLY far off.
White knobbed flyback (with the characteristic cracks around the focus knob), so I thought perhaps the flyback was at fault. Changed it out with no change.
B+ is a bit high (129VDC), but not overly so.
Thoughts?
