It sounds like you have a dying power supply module, that will be the first place to look, look for caps with leaking/bulging tops, some may look OK but can have high ESR (Equivalent Series Resistance), which you will need special cap meter to check that out.
If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:

LG 50 inch tv keeps switching on and off


I'm afraid the power supply is defect, or just any "intelligent" device is generating the IR codes to switch it of and on. Could be an old laptop or a smart phone, with a program to remote control other devices.

I have a 50 inch LG plasma it keeps sticking on a channel and i have to turn it off and then turn it back on to change channel it also gets stuck between channels giving a blank screen


This sounds like a software problem. Have you tried updating the software for this TV. You can download from Internet, save it to a flash drive then plug in to TV. And update.
Hope this helps..

Tv keeps turning on and off


You probably have blown capacitors on the PSB-power supply board. Recaping with new UF caps works 90% of the time. The set turns itself of into a fault protection to keep from damaging more components internally. A few bucks a soldering iron some solder should do the trick.

Have a 50 inch LG plasma tv and it has developed a loud fan like noise coming from it


Hello. Most plasma's do have internal fans that keep the temp down on the internal components. Maybe you have not noticed it if the tv volume was turned up. It also could be that tone of the fans are defective, which would cause them to sound louder. If it is unusually loud, you might want to have the t.v. checked. I hope this helps. Don't forget to rate me if I helped you. take care. Ron
