Turn tv on and no picture onloy sound and then turns off then turns back on

main board faulty check tuner poss dry joints

An electrolytic capacitor has gone bad in you high voltage section of your TV or the high voltage oscilater has gone failed please have tech check and replace

Tv has no picture or sound; will go out while watching. The picture will go into a line and sound and picture will go out; shortly after that tv will turn off. Did this last nite and I did not turn back on until this morning, it worked no problem. On for couple of hours and now it's out again. What could be problem and how do I fix myself

i have had this problem on one of my tv s all i did was remove the back of the tv and re-solder all the joints around the tuner (thats where the arieal goes) they go with time because the joints there get so hot . hope this helps

i unplugged my tv and when i turned it back on had picture but no sound and all cards are still in tack.

I have a sansui 19" LCD TV+DVD
I had to attempt multiple times turning the TV on to get a picture. The sound was fine. This kept happening when I would go to turn on the set the TV kept playing fine with picture & sound but after the 2nd attemts I turned it off & then tried to turn it back on which took multiple attempts, it kept playing for a few minutes then the picture went out but the sound was still there.
The set is not yet 2 years old.

same problem. TV turns on but no picture or sound. when i press power button on the remote control orange light flashes for about a minute and goes back to red.
TV won't turn on. It iz frustating me a lot ay !

Sound
Sounds like your bulb is nearing the end of its life span you will be needing a new bulb soon.

Sounds like the recording and playback heads are dirty. When was the last time you cleaned the heads? If you haven't, buy a Video cleaning kit which are cheap these days and run it through a couple of times. See if that clears it up.
