Check the manual for any reset such as a power up and hold buttons. Try removing the power for 10 minutes and try again. After that, if it's still dead, remove power till the service person can look at it.
Hey guys my Plasma tv just went out and I have been online since last night trying to find a way to fix it. The issue I am having is I don't know exactly what to fix. The problem is as follows.
The tv makes the start up noise on startup followed by a loud popping noise. he light on the bottom blinks then goes away and the screen never lights up. Model number is pn51d430. Its a 51 720 plasma. If anyone can point me in the right direction that would be great!
