Let's try it this way: If you leave the set unplugged for a day or so you won't even get that (10.7V).
jts1957:
You will be measuring a DC voltage of around 160 volts across 2503.
helixal:
With the TV plugged in the voltage was 154 v.
helixal:
I assume that the 154v is a good measurement with the set plugged in.
Is 154v close to 160V? Um...Yes
Does this rule out the flyback transformer?
NOT even close to that point yet.
jts1957:
Check for approximately 140VDC across capacitor 2561. IF NO voltage, check value of resistors 3523 (100) & 3532 (2.2K). IF O.K., Integrated Circuit 7520 is likely bad.
WELL?
