          I have an LA37B530 with the same powerboard and it is dead. Local TV repairer told me $330 to repair as he said it needs a new powerboard so I brought it home. I am a total newb to working out what might be wrong with a TV. Can you help me please?

          Cheers,

          Check for dry joints on the regulators. Resolder them even if they look ok. Quite common on that era.
