Update:
Found the driver transistor to Q601 was leaky.
Replaced Q601 again (2SC4423), Q604 (2SC3807), fuse.
Powered on with perfect picture/sound... for 5 minutes, then went out
again, same parts.
He's thinking of replacing all the surrounding transistors and diodes
en-masse (stressed?):
Q601,Q604,Q605,Q635, D612, IC601(SE130N).
Will advise of success.
