So when a mostfet shorts out does it take a lot of other stuff with it?
i have a sharp aquos lc-30hv4u and one of the n-channel 900v mostfets burned out. i've replaced the 2 mosfets (since i was in there i figured i'd replace both) and fuse so now i get a red light instead of insta popped fuse. The only problem is that when i turn the tv on with the onboard button or the remote the light turns green like it's going to click on but there's no satisfying relay click and the tv doesn't turn on.. if i click the relay myself it just blows a fuse.
I'm thinking i'm dealing with a chain of destruction and not just one part.
if anybody has any thought's they'd be greatly welcomed. (i've got the service manual and i understand about 30% of it but i'm learning)
thank you.
