Our TV - Samsung TX - R2735 27" - was working fine.Then next day the image and sound came but after a few minutes the sceen became black and there was no sound ! When we tried to restart the TV, nothing happend. We plugged it to a different outlet . I heard a small clik and it came on for sometime , 1/2 h. or so , then went out . ( no image no sound )
No matter were we plug the TV , it would` t start any more !
Is-it a power suply , a fuse inside ( or ....? ) which prevent it to work properly ?

I own the same model of tv and have owned it for over 1.5 years. I moved with it twice. I had this problem about a month ago. On both vertical sides the screen became very fuzzy, yet the center remained clear. When turning the tv off and on I also noticed very wierd red, green, and blue lines streaming across the screen before the picture comes up or after it fades. I found no solution or cause to the problem. But I had two "long-boy" speakers from my panisonic 5.1 surround sound system setup right next the tv on either side. I set the center channel on top of the tv with the receiver on the shelf below. I thought well maybe some how the speakers were cause some sort problem in the tv. I moved the side "long-boy" speakers from directly next to the tv to about 6" away and removed the center speaker from the top of the tv. After several days of normal use of this configuration, the tv turned like normal and the fuzzy edges were gone. The symptoms lasted for around two weeks, and the several days after I moved my speakers. My only guess is that without a deguassing feature, it took several days for the magnitism to return to normal after repositioning my speakers.
You may have an arc in the screen and focus circuits.
Water may have gotten into these circuits causing a delayed reaction. (Circuits Corroded).
These circuits at least part of them are a part of the high voltage transformer (flyback).
Your picture tube socket has spark gaps inside of it too which may be arcing.
You need to have it checked by a tech to find out just what is arcing.
The problem here is moist likly the regulator circuit or the power supply has a defective component in that circuit. This is a solid state set and should not be services by un quailified service perso. Good Luckns
