I would disconnect each crt board and hv lead one at a time and try. Have
seen several bad tubes on that model. The only other problem I have seen on
that set is bad convergence amps, however that doesn't cause shutdown.

Hi Guys, I don`t see many JVC`s and don`t have the print for this AV48WP30,
went out this morning and
as customer claimed on phone when you plug set in and turn on it makes a
loud  thump thump in both speakers
20-30 times then relay clicks, the thump stops, and blue idiot light on
front goes dim/bright, dim/bright, have to unplug set to start this same
scenario over again. Never develops HV or audio,  Will order the service
manual today, but would
like to know if anyone has seen this before (should say "heard" this before)
tia, Larry E
