I have a JVC AV-32770 which is clicking when I turn it on. I have been unable to find a schematic. The relay clicks as though to turn on then click again as though it was turning off. Seems like voltage to hold the relay up must be missing so suspect power supply components. Nothing visibly burnt or discolored. It continues the clicking as long as plugged into power. The front controls have no effect, likewise the remote control. Set is about 9 years old but I hate to throw it away for what is likely a very repairable problem. Can you help me please. Thanks, Robert Martin
