SOURCE: Convergence IC,s overheat

Make sure there is enough heat sink compond between the IC's and the heat sink itself. These IC's do usually run fairly warm to hot but that heat should be disapated onto the heat sink.

Convergence IC + Resistor swap = Blue light clicking noise


Good Day,
It sounds like you may have slightly diconnected a cable. Look for the large RED cable/wire that goes to the Blue tube and make sure that they are very secure. When doing this make sure the TV is off.

Good Luck, BIG IRISH.

JVC AV56wp74 convergence. Resistor before ICs?


It's recommended to replace all the defective parts first because if you only replace the defective resistor, it might burnt again if the convergence IC is shorted internally. I would also suggest to measure the other low value resistors with multimeter.

Screen is bowed (top and bottom) Color has a green and purple tint?


Your convergence has failed and needs to be repaired. Once quick test is to goto your convergence menu and see if you can adjust red and blue. If not its has failed and needs to be fixed. You can call in a repair shop or you can get the parts and instructions from www.TvRepairKits.com and do the repair yourself. Its a fairly easy DIY fix.
