Hi,
I have a RCA (32" picture) TV model F32676SB, ch CTC197CD
(mfg. 12/96) in my shop that shuts off right after turn on. I can hear
HV at turn on. The regulated B+ is 151V in standby.
Using a 250 ohm dummy load, the B+ voltage drops to 141.5V. I do
not have a SM for this set. Is the standby voltage too high?
Thanks in advance, Brad
Take your scope probe and let body of probe lean on the flyback's body
with 50uS/div & .1 V/div. Turn the tv on. If the waveforms looks
weak and noisy, Time for new fly. Fairly common.
That assume you have checked all the diodes for this flyback on
horizontal & outputs.
Cheers, Wizard
