Here's a schematic of the power supply board - the "G" board. Your set uses the MX0841 transistor pair - only the Sony-supplied devices will last. There is a bulletin that has you make some mods and replace some other parts - be sure to follow the instructions, or you'll eat the MX0841 again. Yes, the flyback could also be bad, or it could've been a surge or lightning strike set..
Save the file and zoom in to see the detail - viewing it in the web browser ain't gonna cut it. PM me if you need the full manual.
Anyway, hope this helps,
