If it is an LED LCD TV, the backlight inverter board should be troubleshooted. Contact any service technician.

There are so many reasons for this fault to a Plasma display, irrespective of its brand.

If it is still under warranty, take it back ASAP. The panel could be failing, TAKE IT BACK

I think you are looking at a defective LCD panel. But the set will need to be properly diagnosed to tell for sure.

use your warrenty

I would suspect the backlight inverter is faulty:

I would try to look on the power supply first for popped capacitors that supply the 24v rail for the backlight inverter.

Having sound is a positive when it comes to repair. This means that only your screen is not lighting.

If you repair the 24v line and check the 5v feed also going to the BN_on (on) the backlight inverter and you still have no picture...you will need a new inverter.

This could also be the CCFL bulbs that are aging and need replacement. Those are around $20 each for a bulb

Hope this helps! Please rate :)

t-con board bad

The panel is almost certainly bad. The only fix for this is to replace the whole panel which would cost more than the whole TV.

Try changing the H/V position in the TV Set Up menu. You can adjust the horizontal and vertical position of the screen and move it enough that the green line disappears from the screen.
