When the TV is turned on there is nothing on the screen. Sounds comes on OK after the normal 'warmup" time. This used to be an intermittent problem...if you waited 10 minutes the picture would come on all of a sudden. Some other tech references have suggested a bad flyback. Another user seems to have posted a similar problem for the same model. thx
Lets try something ,turn the set on and put you forearm in the face of the picture tube if your hair stand to static it means you have high voltage and your set is missing possible the screen or filaments volts,if the hair in your arm does not stand your set is missing the high voltage and the problem is related to the flyback but it does not mean is bad ,it could have a loose conection in one of the legs or in the near area,next time it happens tap on the side of the set to see if it reacts if it does you know you have a loose conection.If you are familiar with tv service this will be a good place to start but if you are not too familiar be safe and call for assistance from a servicer.Let Us know if you need more information and how it goes.

I have a Philips Matchine television which does a similar thing, the problem is in the receiver part of the set, where I have traced the Video signal with an Oscilloscope to a particular Chip (Integrated Circuit). By increasing the Contrast to maximum the picture can be brought back again, but still lacks contrast. The fault is varies as the chip warms up. Therefore you can locate the chip by cooling or heating it from a special non inflammable spray can. Have you tried the scart input which may work OK, then you can use the television as a monitor, as I do. Cost of repair is not worth it.

SOURCE: No picture when TV is turned on, sound is OK
try to look at its circuit board and look for cold solder or loose solders usually solders with crack,they might be the problem,i dont think its the flyback coz you have audio.try also look at its picture tube at the back tru the crt if the filament is ok or it may also have loose connections

i soldered all the loose joints of components... and change all cold solders
the set takes about 15:00 min. two warm up
My Samsung tv works well until I turn it off and turn it on shortly after I have sound but no picture. If i leave the tv off for about 1/2 an hour or more it will turn on with no problems any ideas??
I have the same problem to, got sound good but no picture, I try to test the flyback by pointing a screw driver on a pin that goes to the CRT and the arc that produced is just so thin do you think that ther's something wrong with the flyback?
