Lg 42' plasma tv shut it self on and off automatically

Does it give any image att all and have you tried another data source, dvd-player and can i have exactly the numbers of your tv, like how old it is . The change that you have a panasonic screen is 90% and for me still the best way to watch tv, but is it just hd or full hd and what did you pay for it .gr richard

have you got the sleep timer 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.

Hi,

I only hope you have connected the tv with a stabilizer or is it inbuilt? This might be because of Voltage fluctutations. Also, check the connectivity of the internal power card.

getting hot and shutting down try to clean it out could be very dusty inside

With a problem like this, I would use the warranty for the TV.
It's possible a circuit board failure has occurred and the TV is automatically turning itself off to protect it from further damage. Is normally called " Protection Mode " for most TVs.

Being that it's 2 months old, it should be under warranty regardless. I would recommend contacting the store of where it was purchased and have them help you with the warranty issue.

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.

Cheers,
Stephen

Since your plasma is less then a year old, I would suggest to contact the manufacturers to get it fix under warranty. If the plasma keeps shutting off by itself, that is not normal and should be repair.

You need to get this tv service asap.i beleive that the problem is in the inverter board or yb board.


good luck

I wish I had an answer for you but I'm in the same boat. I've got a 42pc5d and it's doing the same thing. I'll turn it on using either the remote or the power button on the unit itself. The LED will blink either two or three times, then shut itself off. I tried plugging the unit into a different outlet. I tried unhooking all inputs (PS3, DVD player, antenna, etc). The tv was still shutting itself off. I called tech support and the lady who answered asked me if there was a power button on the unit. Well, of course I understand LG has hundreds of models but I felt like I was dealing with someone who didn't care enough to even open the manual to see for herself. Anyway, after a "reset", the TV is now nothing more than a very expensive paperweight. To say I'm displeased is an understatement.
