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.

I have pioneer plasma tv about 6 years old. I turned the power on, sound but no picture. Do you think it is worth fixing?


no
plasma tv units consume considerable power and the latest led units don't so for the extra cost of a new unit , there will be a power saving over the years
