I am having an issue with a green WG 19k7000 where it will randomly go into HV shutdown. Sometimes it will happen a few seconds after powering it up. Sometimes it will run for around an hour and then shut down. The b+ is measuring 150-160vdc at both Q11 and R391 when it shuts down.
So far I have:
not found any cold solder/broken traces
new flyback
new cap kit
replaced IC4
replaced R101 - the original was out of spec
replaced Q10
replaced IC2
metered other resistors in the area and could not find any out of spec/shorted/open
Any suggestions of where to go next would be appreciated. I have a few spare chassis that I can use components from. Thanks.
