JVC Vertical Failure
You most likely have all or most of the following components defective in
that unit (these are the usual bad components with vertical IC failure in
these JVCs) so you better check or replace them all:
IC421 (part# LA7832)
D422 (part# MTZJ75-T2) (75 volt zener)
D541 (part# RGP10J-5025-T3)
R541 (1.8 ohm, 2 watt)
C424 (100mfd/35v)
C425 (470mfd/35v)
