    My LG turns on and off constantly upon start up. The length of time it stays on gradually increases, but it still shuts off and restarts.

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

SOURCE: Lg Plasma Display settings keep switching

When you boot up your tv for the first time, you get to choose between home and shop-mode.
In your case, he TV is set to "shop-mode".
Then it will go back to factory settings after 5-10 minutes. (so that customers won't mess up the settings all the time)

So change the settings from shop to home, and your problem is fixed!

Check for a popped capacitor on the power board. They are the round tube looking things with a cross or cross type shape on the silver flat top. Check they have not leaked and are still flat topped. The one your looking for is about 8mm diameter on right hand board. Take the back off, i suggest putting it face down on a mattress with a blanket support. Take care not to lean on it. When the backs off you will see 3 circuit boards the power board is the smaller of the 3 on the left, looking from behind. Good luck.

You can't upgrade a panel tv, plasma or LCD.You may have had a plasma panel failure,I sell LG tv's and for the panel to go bad is rare but I have had it happen approx.6 times in the past 5 years.I highly recommend contacting LG"s customer service they will stand behind the panel and get you going again.Good luck!

Lg plasma mt 42pz10


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.
