Could be a bad flyback transformer and shorted horiz output.

You should call for warranty service. If the set is very new try to get it exchanged.
There are some very heavy duty power supplies and many high power matrix drivers used in Plasma sets.
The description sounds like the noises are very loud. It is normal with any of these TV sets, if you put your ear right up to the back of the set at the vent holes you will hear some noises. These would be some acoustic harmonics from the power supplies and related circuits.
I am wondering if it is possible that there is something that is becoming less stable. If the set is working very well without any failure, so-far this is a very good sign. Before it gets to be a problem, I would have this checked.
On many models of these sets, they use fans for cooling specific areas. A bad fan can cause noise.

SOURCE: TV will not turn on. Clicking noise heard from inside.
These sets use what is called a "switch mode" power supply. In order for them to work there is a capacitor that "kick" starts the process. If that cap goes bad, the power supply will not start up. Also, there are other caps inside that maintain the oscillation required for the power supply to work. There are 2 options for you here.
1) Replace the entire power supply module.
2) Repair the existing one.
Sicne these types of power supplies are not the easies to diagnose or repair, I would suggest that you replace the power supply module. That should resolve the problem.
Please note that there are other causes of the reported problem, but hte power module becoming defective is the most common.

The clicking noise means the computer board is bad. It will have to be replaced.

Hello
If cable box converter has damaged, there is no question about the main board of your TV. It has been damaged. Before replacing it, you have to check the power supply board also. If the TV has been pluged to power supply, surely there will be fault to it also. We can't predict the exact fault occurs during a lightning, because Trillions of volts are passes nearby. You have connected the TV with cable connection and to the home power supply too.
Just replace the main board first. If it does not hel you, replace the power board too. I hereby send picture of both boards.
The first one is main board and the other is power supply regulator board.

Hi
There are some factors of this kind of problem.
First you could have a failure in the power supply. Next could be the main board. Lastly you could have a problem with the panel itself, this would mean a new set for sure because the part cost is more than a new set.
However try troubleshooting the problem before spending money on repairing or replacing the television. Possibly you can restore the picture and sound to your television ...
Verify the TV is powered on by pressing the power button on the TV's remote or the front panel of the set. This may seem like an obvious step, but many TVs are equipped with a standby light that will illuminate if the TV is turned off, making it appear that the TV is on when it is not.Cycle through the TV's video inputs to verify that your TV is set to the right one. For instance, if you are attempting to use a digital cable converter box that is plugged into the Video 1 input and the TV is set to a Video 2 input that has nothing plugged into it, the TV will not display any picture or sound and may even say "No signal" on the screen. To cycle through the inputs, use the input selection button, typically labeled "input," "source," "TV/video" or the like.
Re-seat the video and audio input connections to verify a loose cable is not causing the TV's loss of signal. If you have a coaxial cable connected from your wall cable jack directly into the TV, it may have come loose thereby eliminating all picture and sound on the TV. Locate the connection cable or cables of whatever device you are attempting to watch and unplug them from where they plug into the TV. Plug them back in and check for a signal. If there is still no picture or sound at this point, the best option is to contact technical support for further assistance.
