Check if there is back light on or not?
If back light is on means this unit is having problem with panel (deffective.).
If there is no back light change main baord.

If your TV is less then a year old, still under manufacturers warranty. If not under warranty the defective parts could be the power supply or the back light inverter board. Both boards can be replace easily.
The way to know if you have a defective backlight inverter is by shinning a light from a flash light near the screen with the TV on and check in a 45 degrees angle if you have a dark video in the background, if the video is present then you have a backlight board failure. If no video, then is a power supply failure.
I have both boards if you want to buy them.
Let me know if you require further assistance.

the pic attached is an electrolytic capacitor, they come in different sizes and are usually blue, black and sometimes yellow. depending on manufacture.
most of the problems I have heard of tvs having problems with the electrolytic capacitors going bad. if you open the tv and see one of those swollen or leaking you need to replace them.

I suspect that your supply has gone bad. You will need to find the service manual for voltage measurements. If you want to get replacement boards many can be found on ebay or you can check www.shopjimmy.com they stock boards for many units and I have had no problems.

You do not need to buy anything, just look at the owner manual, or look at yor remote control for the button with 'DISPLAY', 'ASPECT', 'ZOOM' for adjusting the aspect ratio.

Or www.digikey.com just make sure to use caps with low ESR, 105c, high ripple current, long life rating such as PANASONIC FM or FC series.
