This is from power supply failure most likely. Do a google search on your model number and you may find an epidemic of this problem that others are commenting about in forums. That my lead you to the solution for your model.

SOURCE: no picture just comes sound

sounds like the Backlight has failed, if you look closely at the screen you should be able to see the image changing, but as there is no back light there is no luminescense so it will appear black or grey, It is probably the backlight inverter or element that has failed, if this is within warrany organise with them to fix it for free,

The clicking sound is the relay switch on the power board, it could be the power board or the logic board

SOURCE: 42 inch LG Plasma TV - Lost picture

Our LG 50" plasma tv screen went black after a popping noise but still had sound, after great diliberations decided to take the back off and have a peek!
We unplugged the tv and tested the fuses (there were three we could see) one had blown, the one on the left as you look at the back of the tv it also has one above it. We wrote the code/seriel number down and took the fuse to the electrical wholesalers Maplin and bought a pack of 10 fuses for £1.29 replaced the fuse in the tv and everything now fine!!!!!!
Hope this might be of use to anyone whose lost the picture after a loud popping/snacking noise but still has sound.

SOURCE: LG 60PC1D making clicking sounds

Hi
A common problem for these is bad capacitors in the power supply, Remove the back from your Tv and look at the power supply on the left hand side.

You will see roughly around 9 x capacitors that are bulged / domed shaped on top usually these are valued at 3300uf 10V any that have bulged or leaked a brown like substance should be changed.
This will cure the problem as they overheat being sat next to a heatsink that gets very hot!
Try and change them for the same 3300uf but a higher voltage.
Hope this helps

When powered on the tv makes a constant clicking sound


THe clicking noise is the relay on the PSB that allows AC to be sent to the psb. It won't hold in due to some fault either in a resetable link or some other safety component. To check this unplug the cord from the mains for an hour, then try again. You should hear the relay click once and then the TV will power on for a short period before powering off again. The solution is to replace the component, other than that replace the psb. I can't get a manual to prove this so I am just making an intelligent guess until I can prove it.

This is almost certainly the device that sends electricity to the the plasma in the panel after failing. Bring to your local repair shop and expect to pay 300-400 parts and 100-200 labour.

I loose my picture but i still get sound


Just try to reset so picture will come again, some LCD TVs have a reset button. If available and accessible, try using the reset buttons before using the steps below. Using the reset buttons can save time.
1. Unplug the LCD TV power cord from the power outlet.
2. Unplug any connected devices (DVD, Set-top boxes, etc...)
3. Press and hold the LCD TV power button for five seconds.
4. Plug the LCD TV power cord back into the power outlet and turn on the TV.
5. Open the on-screen menu to confirm that the LCD TV is responding again.
6. Turn off the LCD TV and reconnect the devices.
7. Turn on the LCD TV.

Hope it may help you;

Regards;
