Howdy folks,

Got a 25" k7000 board that's really been giving me some trouble lately. It came to my bench with a blown HOT and voltage regulator, as well as some out-of-spec resistors (R89, R101, R96).

I replaced the HOT, the 30130 regulator, and those resistors and it powered on for about a second before going completely dark. I metered after and found the HOT and 30130 shorted, and R103 now open (it had been reading 3ohms before testing).

I've checked just about all of the regular suspects and everything checks out, so I'm beginning to wonder if the flyback has gone bad, even though it's only about a year old and shows no cracks or arcing burns.

Any ideas? I'm relatively new to monitor repairs so maybe I'm missing something obvious?

Edit: the 2A fuse is not blowing.
