I have a jvc av-65wp74, I replaced the convergence chips and resistors from the tvrepairkits.com hoping that would fix the tv. But it didn't, so now I'm asking the forums to see if anybody has an idea where I can start. When the tv is turned on the sound will begin to thump, queit at first gradually getting louder, does this for a minute than stops and nothing else will happen, just the light will blink. None of the tubes are even turning on (should have been the first clue that it wasnt the convergence chips). I've looked over all the capisitors and wires, everything looks good. I am thinking might be one of the generators, or flyback i think is what it was called. But don't even no how to even test thoughs.
