Same thing happened to mine and some guys came to look at it, turns out the main board had to be replaced, they say it went because the dust was blocking the cooling fans. I think mine is more modern as when ot went off the power light flashed 8 times, which was a code for what was wrong. See if yours flashes anywhere and look it up.
Hey kangus2000 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

Sorry to tell you a common problem with these sets. It is a bad capacitor in the main power supply.. There are really about three of them that go bad from time to time to cause this problem... If your not a tech you should find an authorized repair facility as a non authorized is not going to know what to do to fix it and it will most likly cost you double to repair. Good luck and let us know how you got it fixed.

Hold The Off Button for 20 sec should make clicking noise switch off at power and on again should be working

If there is no LED burning to indicate there is power than the power supply is faulty.Repair is not verry easy to do with these complicated power supply's.

You have some dried out capacitors on the power supply. Samsung has a major issue with this right now and I made a tutorial for that repair in my Tips & Tricks. Your capacitors will not be the same, but identifying them and replacing them will be. Best advise I can give you: Stop using the TV and unplug it until you get it fixed. When these caps go bad, they draw down the voltage they are filtering. I've seen some TVs that had secondary damage because of this. I hope this was of some assistance, best wishes.

Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.

First of all you need to call the technician and ask that might have the problem of screen if that is the problem then without contacting the technician it is not possible.
