You can try leaving the TV unplugged for 30mins; so the Tv can reset itself.
If that doesn't work, the leading cause of the problem is the power supply module for the screen. Normally it's call the Backlight inverter board. It's the #1 problem with flat panel TVs, because the screen require a lot of energy to power them and the power supply for the screen tends to burn out. I'm sure if you replace the circuit board that powers the screen; it should work again.

a rca cables from video/audio out on the set to
another set vid/audio inputs to see if it the video gets
through.This is a problem that requires technical
knowledge and test equipment to trace the video

T.V. comes on, there is sound but no picture.
T.V. is les than 18 months old. We use the T.V. when we come to our Condo in Daytona Beach for vacation, so it hasn't been used very much.

The backlight inveter board may have gone out ,or the power supply is not working to supply power to the inverter board, those are the two places to look.
