Phillips Projection TV chirping noise

Hi: My 52" projection TV is making a chirping noise with no picture/sound. Last year, I replaced the convergence chips but they were from china, not Sanyo ones. I removed connector 1516 to isolate the power board from the convergence board and the chirping goes away. With connector 1516 removed, all 3 lamps (green, blue, red) light up for a few seconds and then go off. Does this mean that the chips are bad? I thought the lamps would stay on indefinitely? Could there be a short or bad component in the power board? ANy help is appreciated. Thanks
