Question about Televison & Video
It may be mainboard, or the power supply with the issue. Either one will cause that symptom to appear. You tv may be done for. Is it under warranty?

It is the fault with its main digital processor board itself. It should be replaced.

You need to do some more diagnosing of the problem. If you get sound and change channels take a bright flashlight and place it again the screen. Look for an image around the edge of the flashlight.
If you see an image that means the LCD controller board (TCON) is probably good.
The problem is probably one of three causes;
1) Inverter board is bad
2) CCFT (cold cathode fluorescent light) are bad.
3) Power to the inverter board is bad. You can also check the connectors.
