That sure sounds like it may be a bad micro. Perhaps others more familiar
with JVCs can give you some better assistance.

If I repeatedly turn the set on via my isolation transformer 2-3 times
I have a normal raster and video. If I force on by jumping the relay
the picture will remain normal but after 4-5 seconds I lose audio but
good raster and video and all controls have no effect. I forgot to
mention I unsoldered the VCC to the Vertical IC and still had shutdown
