Sumsung LN-S4051 my flat screen 42" 18 months old, the sound went off and then shortley later lost the picture. The red light kept going off and on but no picture or sound. I unpluged it for several days, it came back on for 50 minutes then no sound and later no picture. I just turned it on after being off for 2 weeks, I have a picture but no sound.

    Exact same problem for me! I had problems with the tv turning on and then sometimes it would come on but no sound. Finally it just went to a constant state of beeping and the stand-by light blinking on and off with nothing else happening. I even unplugged it all night but it just goes back to doing the same thing when I plug it back in. So annoying!

Screen goes completely out.


when it blanks out, tuen the lights out in the room, and shine a flash light at the screen, see if you can see the picture, if you can, it is the inverter moard blamking out, thats the board that lights the back lights, if you cant, hit the input button on the remote, if the TV comes back with a picture, it is a problem with the main board, in paticular the componant input on the main board

Sound yes, but no picture on tv


If you have sound on the stations this is a problem in the display. Take bright flashlight and hold it against the screen. Look for an image around the edge of the flashlight. If you see an image then it's one of three problems;
1) The inverter board is bad.
2) The CCFT (cold cathode fluoresent light) are bad.
3) The power supply to the inverter board is bad.
Someone knowledgeable in electronics can replace the bad part(s).

I had a problem with a Samsung 46 inch LCD and it had audio and dim light but no picture and found out that the logic board toward the top (inside tv) was bad and was no longer available and the only way to fix it was to get the entire display panel (the logic board came with it) It was not costwise to repair. Hope this helps.

I could be wrong but sounds like your plasma display is going bad. What is your model number?

Samsung 40 no picture


If it is only 6 months old you probably still have a warranty. This is definitely a hardware issue, and unless you are comfortable taking your new TV apart, I would contact Samsung for repair.
