Could be,might not also,any things on the power supply board could be burn and dies,when it getting to much electricity current to it.Dead or dying capacitors on the power supply board are alway bulges or puffing up on it tops.Check the power supply board carefully look at all the capacitors parts,if require replacing,u must have tools like a soldering iron,a desoldering pump or a roll of desoldering braid,a roll of solders,also u must know basic soldering understand basic electronic to do it.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

SOURCE: Toshiba LCD 40 inch tv.

We will need to perform a component level testing to identify the source of the problem. If there is no standby LED and the set is completely dead you will need to test the stb 5V circuit with multimeter. That should help us figureout if the power supply is the source of the problem or the main board.

Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

37 inch LG LCD won't turn on due to power failure


Power failures can cause all types of problems, have you firstly checked the fuse in the mains plug? If that is ok then it may have blown an internal fuse in the power supply board, these are there to protect the rest of the circuit from power surges.
