Please find service manual and a user manual above. You most likely have a switchmode power supply problem, the PSU, is shutting down, for safety reasons, due to a fault, that may cause a fire and explosion or both. use these manuals to isolate your problem

You may need to adjust the resolution first, keep it lowest possible to get the computer works first. Then, try to reboot computer to get signal in.

if you can open ur tv with out damaging anything your rebon cable needs to be reseated in its connecter which mean unplug it and plug it back in carfully.

sounds like you fried your digital board or power supply not sure need more info on what tv is doing

IF THERE IS SOUND, PROBABLY THE Y-MAIN BOARD, IF IN WARRANTY CALL SAMSUNG

Power supply foult.

My set started having sound issues recently. Every now and then, randomly, I get a split second, static sound. It sounds like an old record player when it skips. It happens on all channels HD and digital. Also happens when I'm watching a DVD. This leads me to think that it's not my cable box (Dish Network). I have a Bose 321 aux amp plugged in. I hear it through my aux speakers, as well as directly through the tv set. Not sure what to do. Is it possible my tv's amp is burning out? What could be causing this?

panel migth be bad, connection/connector on it might have loosen up already! it it has a warranty then return it at once and ask for a new one! its what you've paid for.

the panel itself has failed
