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. ... 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, then it could be the voltage regulator. 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
