JVC HV-53pro rear projection TV. a 53" set.
Fault: There is sound but no picture:
ALL other functions are working fine. However, none of the 3 tubes (R G B) are working as if no high voltage supplied. Checked the high voltage supply & it seems OK. I wonder if there is a shutdown switch somewhere that is activated for no apparent reason. The sound is perfect.
Any suggestions to resolve this problem is appreciated. Thanks, Paul.
