LG 42lh200c no standby

[superg]

hi
This tv had a dead lizard stuck under the power supply. I immediately assumed a bad power supply but on further checks found the 5.2V standby fluctuating between ~1V to 4+V. Unplugging the main board and it remains steady. Am I looking at a faulty main board?

Put 10 Ohms 5W resistor to simulate 500mA load as the load to see if 5.2V will be stable. Pictures of the board? It sounds like bad startup cap.
