I assume you checked the driver transformer pins for bad solder and any litic caps in the driver circuit? Paul GRAYSTV@xxxxxxx wrote: We have a Magnavox PTV 620-AH01 Mod. FP5230 that came in with a blown Q802. After checking some components and connections, I replaced Q802 with an ECG 2353. Pix looked good for about 5 to 10 minutes then seemed to briefly go out horizontally, then to black. Q802 shoted. It was not running hot. I began checking caps and the 330pf 2K was off value. It reads 300pf. I can't get a diagram for a few days. Tempted to put in another ECG 2353 with a good C811(330pf,2K) and try again. But I'm not thoroughly convinced this is my total problem. So I put it aside to ask for some advice. Would appreciate any advice. Thanks.
