SOURCE: 50 in LG turns on and then clicks and turns back off

The power supply is going in to protect mode. Most often this is a power supply failure, or a failure on one of the circuit boards that is causing the power supply to go in to protect.

If the power supply fault is not too complicated an experienced tech may be able to service it without changing the compete circuit board.

The tech will service this by substituting boards to determine where the failure is occuring. Then he will change the board to fix the fault.

SOURCE: LG TV NOT TURN ON

To let you know , there jave been may claims against this 42" model There were some models released that had faulty power boards and video controller boards. LG recalled many of these to have them replaced

No picture and sound is Y +Z Sustainer problem.However, normally they have to change both Y Sus and Z Sus boards atthe same time. If you lucky than it's just a fuse on the Y sustainerblown (the chance is very rare) otherwise the IPM (Intelligence PowerModule) on the Y/X sustainer board is short. This is a common problemand costly to repair.
Is it under warranty or Extended 5 year warranty? If so get it repaired now.

Call customer service for help 877-543-8325 to try them first

If you are skilled in electronics the cost of parts is about $250 online (Otherwise add another $400 for labour and travel if you use a tech ) Always ask for a quote first))
Just ensure you select the right model as i am unsure this link is correct one. But the place itself should have your model

The TV should be under warranty. Send back. Sounds like the panel is faulty (half the value of the set).
