The clicking you hear is probably caused by a relay that controls the incoming AC to the main power supply. This is a protective reaction to a problem in the power supply itself or an overload due to a failure downstream from the supply. This is not a likely DIY repair. You will probably need a technician to determine which of these two likely problems it is.

JVC AV-65WP74 clicks and sounds like a heart beating and then turns off. what is the problem, how much will a repair cost?


it could either be convergence ics shorted or deflection board trouble
as to cost convergence 300 to 350
if its power supply 300.400
it would have to be isolated down to the exact location causing the problem
but usualy a great set to keep around

Hi, sounds like your convergence IC`s have failed if one of the colors doesn`t adjust either up/down
or left/right. If you have soldering equipment and are very proficient at soldering you can replace them. if not you definitely need to call a tv tech, if you need more info ask away, video-tek
