In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Hello,
does it turn of precisely after 5mins each time you turn it on? If yes, then there is every possibility that the TV timer is set to 5mins and when it gets to that time, the TV will eventually turn of itself.
But the TV doesn't turn off in exactly 5mins all the time, then it is having a power related problem in as much as the TV turns off on it's own.
The problem is consistent with overheating on the power supply board of the TV.
The power supply board of the TV has few capacitors and IC. If any of these IC's gets short or become weak, it can cause the TV to turn off on it's own.
When current passes from electric outlet to the power supply board of TV. The current also goes to the weak/faulty part, then the current stops or slow and the board overheats and TV shuts off on it's own.
This is a common problem faced by many other users too. To solve this issue, check the power supply board and read it with a meter and continuity tester, in order to detect the faulty part and replace the faulty part on the board which is short due to which power supply board.
It's a bit technical job but yes its not at all a costly repair to do or get it done by the technician.
You can buy this part at any Fry's or Radioshack store or you can order them online at vendors like "mcmelectronics.com"(look for electrolytic capacitors). After replacing these capacitor (capacitors) most likely the normal operation will be restored. Or you can buy a refurbished complete power board to save you some stress.
If this task is too technical for you, you can call a family or friend who has the ability to assist you (two heads are better than one).
Good luck.

need code reader to get out or try dis-connecting battery for 5mins and re-connecting.

Probably something wrong with the lamp. Buy a replacement.

the software in the main control is damaged. call your lg servicer in your area. he might get you a software update

This sounds like an overheating problem. Newer games are graphic intensive and the cards required to run them generate alot of heat. You will want to make sure your laptops's vents are free of dust and then check the fan. To get the best performance you may want to upgrade the fan. If your fan is working properly and the vents are free make sure you are playing with the laptop on a surface that does not obstruct the vents. You could also purchase a product like a laptop cooler which basically is a cooling pad that you sit the laptop on while in use. Good luck & I hope this helps.

it sounds like you are having a BIOS prob

This happened to me and the tech came out and change the pressure switch and it worked fine afterwards
