This one is turning my beard an even whiter shade of grey. I hope someone
can give a suggestion (other than hair dye).
Set is a model CT-36622V chassis APEDP288.
Uses a STR58042A regulator.
Came in with shorted HOT and shorted 150V zener protection diode. Regulator
was running very high feplacig several electrolytic caps fixed this. Set now
has decreased width (about 1/2"). Width and PC adjust seem to be
functioning. Checked all tuning caps in width circuit-all ok.
Replaced PC modulator diode-no effect. Changed regulator (yes, I used the A
version). No change.
Wondering now is the power supply running at proper voltage? Measures 132V
no ripple at input to flyback transformer. Anyone know if this is correct
for this set?
Any other ideas?
