The cycling of power is not caused by the power supply. Your problem is with the Main PCB assembly (Board with all of your inputs) This board is model specific. Find your model and do a search on ebay..You may find your part there.

SOURCE: 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.

42 INCH LG PLAYS GOOD FOR A MINUTE OR TWO THEN SPLITS OFF INTO SCREENS NO SOUND


Fault with the main power supply regulator board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. 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 power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and precious time.

Tv shuts off after only a minute of play


Hi!

Sounds like you have a bad power supply board! This is not hard to do yourself, as long as you are somewhat handy! Take the case apart (back side), and look for some bad caps (capacitors) on the power supply board. They will look bulged on the top an may be a little leaky (brownish stain).

If you see this problem, you can buy a new power supply at www.shopjimmy.com or ebay. You will need the make and model, of your tv to order! Good luck, I hope this is helpful!!
