...Working on the 7th K7400 so far this month(there's plenty more glaring at me in a box)...
This one is in shutdown,
-HOT was shorted, replaced and hasn't blown since
-Changed C713, C730, C155, and C107
-Swaped IC U701 with known good one
-Flyback was cracked near focus pot, was replaced with new one
-Polypropylene caps in horiz. section checked OK, nearby diodes are good
Still stuck in shutdown, the B+ voltage is around 20vDC
