Hello,
Trying to restore above TV have sound but no picture because HV is about 800
volts. 1b3 is ok so is HV osc. 25l6. All components and voltages in HV osc. and HV rect. section check within specs. 1b3 fil. does glow. Adjusted feedback spring on 1b3 but still can't get HV above 800 volts. What am I overlooking?
