I'm looking for a replacement convergence board for my Jvc AV48WP74 tv. SSB-5068A-M2 I've replaced the STK392-150 ic's already and after a week they failed again. JVC does not return my calls.


A Google search for the board part number returned several sources. Here's one. You should also check the values of resistors around the STK's. When the IC's fail, the resistors can change value which can cause the repeat failure you're experiencing.

Jvc av48wp74 horizontal convergence unadjustable after after repair


you have to lift one side of the resistor from circuit in order to measure resistance otherwise a open resistor will not read open as you will be reading the resistance from the surrounding circuit. Always lift one side of a resistor out of circuit when testing with a ohms meter.

ConvergenCE problem still after replace the chips


Check the resistors on the convergence board by the IC's. Chances are that 1 or two of them are open. If you can't fix it, you can remove the convergence board and send to PTS electronics and have it rebuilt.
