Helping out a friend with a K7300 that had a blown fuse and flyback was cracked. Replaced flyback and did a cap kit. Tested Q801 was bad so replaced it. Powered up and Q801 and R812 popped and tested D805 as a dead short. Replaced both Q801, R812, D805 and Q801 blew apart and D805 is shorted out again.

What else should I be looking for?
