Shaun, I just did one that would lose HV after about 30 seconds. This one also used the 9-1978 module. Not the original problem, I might add. I went through 3 boards before finding a good one. But, how's the convergance board? any sign of discoloration on the fusible resistors? John Myers Myers TV Service Co. 376 E.
