Ron, I'm trying to go from memory,....but,...... If it has an STR58041A for the reg. IC,....make sure you use a factory replacement. Also use a OEM part for the H.O.T. Also check the resistor & elect.cap. off pin # 1 of the reg. IC (the feedback ckt.). This resistor sometimes decreases in value from 180 ohms to as low as 12 ohms. (don't trust the color code, cause it will fade, from being overheated. Also check the soldering on the Horz driver Txfmr., and look for a 1ufd @ 160-250 VDC elect. cap in the pri. ckt. of the horz driver txfmr. Hope this helps, even though it might NOT apply to your model.
