Clicking sound coming from tv

Clicking sound coming from tv

I have a lg 50pk540-ue. When I turn the TV on it clicks then shuts off. After watching endless videos on youtube I decided to change the power supply. I hooked up the new supply and still have the clicking sound. Any suggestions on what my next step should be.

ANSWERS:

"Hi,

Here’s the Power up boot fail troubleshooting flow chart taken from the service manual. This may be a good place to start.

The manual can be used online although it is a bit awkward as you have to select the page number at the bottom of the document every time you wish to change pages. To download it you need to register with the website."
