Glenn,
If you have Force32 installed, that manual is covered in it.
One possibility is an arcing CRT shorting it out. You can lift & isolate the
HV lead from the divider to see if it will continue to play. I had one like
this a while back. Tri-state rebuilt the board 4 times & it continued to die
after a few minutes of playing. Finally trashed the set....never resolved.
Lost a bunch on that one. If you resolve yours, let me know.

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.
