Hello, you have a protection circut shutdown. it is usually the power board failing but not allways. its common becuase these internal circuts operate at high heat and handle high voltages these components may become fualty after time with normal use, not holding the right voltage or resistence will the cuase fualts in the circut. becuase these tv,s have built in protection that happens your tv is powering off when it detects any abnormality within the circut .

the best bet is to have it service by a qualified center it isnt easy to detect without the proper equipment. a service center can diagnose it and give you a estimate you will be better off doing it now before it developes more fualts or even a complete shut down..

hope this helps happy holidays

This type of problem usually indicates that the power supply unit for your Lg Projection Tv has become faulty.Either replace it or get it repaired.

This is a common problem 'if it's under warranty the will replace it. good luck happy holiday

Remove the connections of the tv from the main plug and checkout the wire is it proper or looks like burned internally or getting cut somewhere in between.if the wire is proper.then its definately the problem in the main board of the tv .any of the components which supports the tv to function properly is either got loose on the board or become faulty.the board has to be checked out with the multimeter.if the component is loose on the board it can be resoldered but if it is faulty it has to be replaced to make the tv work properly.

My 42 inch LG plasma turns on and off repeatedly when I try to turn it on. happened a few times before when tv was working fine, now it wont turn on at all. I have to unplug tv to get it to stop turning on...


Theres a short between the start-up processor signal on the interface board and power supply. It keeps sending the same start-byte over and over again to the power board. This could also be a DC high voltage shutdown on the power board its self. Now the tv is in protection mode to prevent further damage. Get it serviced at your local repair center. If its under warranty take it back.

This is almost certainly the device that sends electricity to the the plasma in the panel after failing. Bring to your local repair shop and expect to pay 300-400 parts and 100-200 labour.

Most likely what happened is one of the capacitors went bad. When a capacitors goes bad it produces a popping sound. This could be an easy and cheap fix if you find the bad capacitor or capacitors. The bad capacitor will have a bulging top most likely on the power board but could be anywhere.

Unfortunately, that board is the inverter board. And for this model the inverter board is only supplied with the the PDP panel. The panel is quite expensive, here's a link if needed:
