50 inches LG PLASMA TV TURNS OFF AFTER 15 MIN.

This tv works for properly 15-20 minutes then turns off, after 5-8 minutes turns on (via remote), I've been reading about that and people say it's a power supply issue,I'm searching for blown caps and they seem ok, thanks a lot.

A blown capacitor might not be the reason. After 15 to 20 minutes of work, the temperature inside the set do rises much, this kind of fault can occur. Check its cooling fans.

    I mean, the cooling fans, it hasn't

    well, now I'm pretty sure it's about heating, I replaced capacitors on the power supply, and it worked for 1 hour without cover, never went off, then I set the cover and went off after 10 minutes, but turned on, via remote, and went off again after 17 minutes, led isn't blinking, but when I try to turn it on, I hear the click and the LED goes off, when clicks again, the led turns on, but the screen is off. I noticed some overheating on the SUS BOARD, what do you recommend? thanks for your help.

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!

SOURCE: 42 inch LG Plasma TV - Lost picture

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.

SOURCE: tv turns off after 15 minutes of use

For bobby11 and luis, it is the power supply. Part Number EAY34797001 in the 42" and EAY34796801 in the 32". This is a known problem, and somebody should start a Class Action against LG over this one. Part is available online and easy to swap out for anyone with the most basic knowledge.

The power supply may be loose or needs to be replaced. Further testing should be done to determine. It may have a bad capacitor.

Also if you have a sleep mode on your tv, check to make sure it is not set on in the menu
