Ok everyone, this is a very common fault on this model of tv power supply, just keeps clicking on and off.
Your power supply board number should be.. 6709900019A

To resolve the issue we need to change some bad capacitors in the supply these are all the same value 3300uf / 10v

C227 / C201 / C202 / C203 / C281 / C282 / C283 / C271 / C272

All these need to be changed for the same uf but try and use a higher voltage, lets say 3300uf / 25v

Upon replacement your power supply will be like new and your tv will fire straight up.
Hope this helps a few people

Tv is not displaying

Your tvs power supply board probably has a blown capacitor. Just open up your tv and check that all the capacitos37d77cb9-7d6e-45ea-8be1-2a8ddfb09adc.jpga5fe926a-58ed-4064-87cc-b4564a7e4e5e.jpg

As you can see in these photos the capacitor is blown or leaked.

No power coming out of the power supply. Most of capacitor were changed, but it didn't help.

Check your fuse on the power supply. If it is blown, change it with same value fuse and hope it doesn't blow again. If it does, or it wasn't to begin with, then you need to replace your power supply.

Heard a pop noise from LG 60PC1D tv, tv shut off and now the picture looks like a negative kind of...what is wrong?

Capacitor on the power supply popped and it is not allowing the proper voltage to be reached to the main board. This is messing up your picture. I would repair it before you create more damage from the blown capacitor on the power supply.

Please rate if this helped :)

My TV turns of and on by itself

It is power supply mistake. There are regulators fitted inside your tv circuit board, which are directly soldered to printed circuit board. After years of age, the soldering points gets heated and cooled, as the regulators will get heated while working. Re-solder the junction will rectify the problem.If it does not help check for any short circuit in it. A small value high voltage capacitor fitted to the collector of the horizontal output transistor, usually [330pf 2000v] will get shorted to earth. If it gets shorted it is an effect of direct short to the 120vDC power supply rails in your tv
There's a problem with the power ic board. Open it up and look for a burned capacitor. De-solder the piece out and replace with a new one that matches the same specs

i.e. bad capacitor in power supply

Open the back cover of the monitor.. check the fuse at the power supply board... If the fuse is open, replace with same value.. at the power supply board check for any blown capacitor and replace it with same value. Check also the power cord for open connection.

My lg tv wont turn on.

First, I would try leaving the TV unplugged for an hour so the TV can discharge and reset itself.
If this doesn't work, it maybe something simple like a blown fuses inside the TV that needs replacing.Radio Shack or some electronic store will carry the fuses.
If the other two ideas doesn't solve it, we're talking about a power supply board related problem. I can't actually look at your TV over the internet. But, the most common problem with flat panel TV are the power supply board for the screen itself and the main power supply board for the rest of the TV. Commonly a bad capacitor or transformer will be on the board.
If you have some electronic experience and want to repair it yourself, you can sometimes find a Service Manual for your TV over the internet. Normally, costs less than $20. It will have diagrams, schematics, and part number list for the TV.
