Sears 25" T.V. (JVC) !!

Sears (made by JVC) 25" 57-14367 chassis A-53.
No startup, or high voltage, relay clicks, led flashes.
LA7832 vertical IC replaced, with capacitors (very
common), still the same. IC had bad resistance. Looks
like no horizontal drive. Main IC (jungle) failure? Usually
the vertical repair, is all that's needed here. Any common
problems? Rono.

Make sure you have resistor replaced and diode off one pin of flyback
transformer for the vertical's power.
