It could possibly be something wrong with the computer inside the tv. And you can either pay to get it repaired or buy a new one unfortunately. I would try to contact the makers of the tv though first and make sure to have the model number and all of that ready.

Samsung plasma won't turn on


Here's is what you need to look for when describing a problem for troubleshooting purposes:

0) What model is the TV (you've covered that)

1) Does the TV respond to command to turn on?
(yes - continue; no - 70% bad power, 30% bad main board)

2) Once it responds (clicks), does a front LED or other indication show that it turns on? It's OK if there's no display.

(that can be model specific and is not certain indication for anything until known what is specific for the model)

3) If such an indication comes up does it remain on until you act or does it go off by itself?
(Stays on - power supply likely good; turns off - power supply *may* be good, but not certain)

4) If the power indication stays on by itself can you make it go off by pressing the power button or do you have to disconnect from AC power?
(responds to power off - 90% power supply likely OK and 90% OK main board; does not respond to power off - 90% bad main board)

Here is a link for test/repair of the power supply of your TV, hope it would help:

LG plasma 50 inch tv with a fine vertical black line in the center of the screen that runs from the top of the screen to the bottom


Try changing the input device to something you are sure works. Switch off TV manually, switch off power, remove plug and retry after 48 hours. If problem persists, please refer it to a qualified service technician.

Turns itself off


i believe that this set is built with fans to cool down the inside, check if the fans are running slow, because that could be your problem since you get both sound and picture. i think  that's what it is.

Tv turns it self off after only 2-3 seconds and makes crack noise


Since the set is less than 1 year old, it should still be under warranty. Request warranty service.

The noise you are hearing is probably arcing inside the set on the power supply board. Continuing to attempt to turn on the set will only make things worse. Please request warranty service as this is unusual for a TV that new.
