So I have this G07 that was dead. Blown F901 & shorted HOT. Replaced both and it comes up, but goes right into HV shutdown. Works if I pull X701. Measuring B+ gives 141v. The b+ voltage doesn't seem to change at all when I adjust R909. I measured R909 with a meter and it seems to be working fine.
All the diodes in the rectifier test good. I pulled and tested X901, X902, and X04. They all tested good. I swapped X04 with one from a parts board. Same problem. Lifted a leg of R908 to test it, and it tests fine.
I did some searching and other threads mentioned C511 causing this issue. I pulled it and it tested okay. I was going to swap it out anyway, but the only one I have meters at 70uF instead of 47uF, so I just reinstalled the component that was there.
Not sure where to go from here. Maybe R910? Can I measure that in-circuit, or do I have to lift a leg?
