Fault with its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here.

These are generic instructions for all TV's and all Remotes:
1. Press 'Menu' key on Remote (or 'Setup' key).
2. Go to Setup, View, or Picture tab (whichever one you've got in your Remote's Menu or Setup)
3. Change your Zoom or View aspect.
NOTE: Depending on the dimensions of your TV, you simply may not be able to view the entire picture using a correct aspect ratio (NOT stretched). On my 42" RCA is use a 4:3 Zoom setting to fill my screen but, it chops a little bit off the top & bottom. It's the best I can do with my current setup.
Aside from the customer controls you might be able to turn the screen controls up a bit to get more brightness, they are on a black block inside the set.
This is a very easy fix. Your cable box is not grounded correctly. To fix this you need a AC Plug adapter. This will change your TV ac plug from a 3 wire to a 2 wire. This may sound funny, but trust me on this. I have fix a lot of TV in NY doing just this.
