TV will not come on

The first things to try are of course the simplest. If you have a picture on your TV but no sound, the problem might be as simple as having the “Mute” button the remote having been accidentally pressed. Grab your remote and unmute the TV by pressing the “Mute” button again.
Next, check what the input setting is on your Samsung TV by hitting “Source” on the remote and cycling through the available inputs. If your Samsung TV’s source is set to a component that you don’t have set up, then there won’t be any audio data coming in to be played.
Do you ever use a headset on your TV? Gamers, in particular, might be using a wired set of headphones plugged into an audio out jack, and if the headphones are plugged in, then any audio is being routed to that equipment, and you might not hear the sound playing if you aren’t wearing the headset. Assuming you never use a headset on your TV, check the headset port for any debris. Your TV may pick up something in the port which won’t allow the audio to route properly.
Finally if this does not work,you can try the old school way...unplug the your TV for about an minute.

I say press the input button until you see a picture!.

most times then not it's the capacitors on your power board that blew there for not supplying the tv with enough power if you open it up and check the capacitors it should be leaking some kind of liquid or the tops have bubbled up. its an easy fix cost>>2 dollars each

THE POWER SUPPLY OF YOUR TV WAS THE PROBLEM,YOU COLD SOLDER THE MAINBOARD OF YOUR TV,AND THE CRT SOCKET CONNECT TO THE TUBE IS ALSO COLDSOLDER,.

when you have the cable connected to your tv. turn on the ps3 but hold down the power button for 4 seconds and it runs the settings screen and puts it in the best setting for the cable connected. hope this helps

Was there a color or sound problem prior? If not you can replace convergence amp and vertical output these are the main problems with this set. No high voltage is what's happening sounds like. Look to see if after you press power you hear sound coming from inside. If no sound then converg. if sound then vertical

How many times does the light flash, as there is a code that can give an indication as to what circuit is bad.
