I hate to say that's a very open-ended question. If I were to solve it myself this is how i would check the TV.If it's giving you a black screen that probably means its not getting a video signal.
1. what source dosen't have picture?, try another source does it work
2. Try a different input on the TV
3. Try different cables to see if their bad
4. Try a different source

These steps should help you narrow down your problem.
If the problem continues then you might have a bad switch board. That is very unlikely however.

My 5 year old plasma tv has sound but no picture what could this be?


No picture as in a black screen? or a picture with snow (noise)? If there is no picture at all (black screen) with no menu display when menu button is pressed, then it sounds like the y-sus and the z-sus boards are faulty..These are the boards located usually on the left and right edges of the screen.
