This issue is a common, but hardly talked about from LG. Your tv is probably 1 or 2 months out of warranty, and now you're hearing a series of clicks. After weeks of fighting with LG to replace my tv, i decided to fix it myself. i'm proud to announce that my 50PK540 is now working. want proof? Take a look at the video i posted on youtube, then you will have a better understand why your tv is clicking... I'm also selling the repair kit for this power supply board on ebay now. LG power supply Board model number EAY60968801. With anyone of these PCB # EAX61392501/7, EAX61392501/10, EAX61392501/11, or EAX61392501/12 with the parts if this kit, I've also fis several 50PK750 models, Some clients have send me their broken power supply board, so I can do the repairs. Please Make sure that you've already gone through the process of troubleshooting and testing your tv's power supply board before making any purchases.. I recommend that you get a tv tech to check it out, because every tv is different. Email at [email protected] if you have any question.and watch the video:

Sounds like a capacitor blew in the power supply, particularly for the high voltage side. Then the power supply shutdown altogether. Sorry, but you will have to contact a service center or manufacturer for repair. Given that tv is 2 months out of warranty, the manufacture may be willing to help as a courtesy, but don't expect full coverage.

TV Turns on (Blue Light) and then turns off but there is no imagae or sound of Tv Turning On! Nor Backlights turning on!

Sounds like there's a short in the power somewhere. I'd start with unplugging it then checking to make sure all cables and/or cords are properly connected (i.e. make sure there are no loose cords anywhere)

My lg plasma 50pk750 turns on for a second and then you hear a click and turns itself off. tried unplugging it and letting it sit but it still does the same thing.

I think i could be a power supply issue... If you have the courage to open the back cover of your tv, and you do "NOT" see any bad (bulging ) capacitors on the power supply board, then it could be the voltage regulator. Take a look at the video i posted on youtube, then you will have a better understand why your tv is clicking... I'm also selling the repair kit for this power supply board on ebay now.

While watching tv it suddenly cut off,now it is making a clicking sound and will not turn back on

If you remove the back you will find a couple of electrolytic caps that need replace, and/or just replace the power supply. That should take care of your problem.
