That is a plasma and usually power supply board. ebay search your model number. Also look for blink codes on front if it locks up. lastly check for software upgrades for you model thru google
look for the board with coils and big capacitor on it. that will be your psu (power sapply unit) the image below is not your board but just a refrance as to what a psu "can" look like. try "googling" PSU board with your tv model.
Sounds like a power board issue? Dry joints on the main board? Capacitors may have issues.? I would not go opening up the TV if you are not aware of the potential dangers.
You have main board issues, there is a 3.2 volt regulator on your TV that gives issues and will make the set turn on at random times, replace the main board and it should fix it, or you can order the part for under a buck from China and replace it yourself if you have soldering skills
If the tv is still under warranty, this can be repaired at no charge.
However, if not under warranty, you will need to have the CAPACITORS on the main power supply circuit board tested (or replaced).
The capacitors responsible for the power supply can sometimes fail - open the back panel. If the capacitors on the main power supply board look too fat, or signs of burning near the solder joints, then you've found the problem.
This issue is related to the TV's main board not seeing constant A/C power to unit so the board is turning off the TV. When the TV's main board see A/C power back to the unit, the TV will try to turn back on. This issue could be a loose power connection for the TV or a failing part inside the TV. Do other electrical devices work when plugged into the same wall outlet? Try the following: 1. Remove the cord from the back of the TV and reinstall it (perhaps it's loose going into the TV and was not installed correctly). 2. Try putting the cord into a different wall outlet (perhaps it's not a good outlet). 3. Try using a new power cord for the TV. (Any matching cord will work for testing)
If the above did not resolve the issue, then it could be the switch mode power supply and or the main board inside the TV. Both items are easy to change out. I can look up the LG part number for you.
it looks like a faulty mains board. you need to upgrade the tv software with the latest update. if the tv is not accepting the upgrade then it can be a crook mains board. hope it helps! please rate my comments :D
