Re: tv turns off in 10 seconds or less
Usually on that models its a defective Flyback they are very inexspensive and easy to change. You need flyback 259296 for your model not positive thats the problem but it usually is.

I have a sony bravia kdl 40v 5100 for less than two years and i did not purchased an extended warranty and now my tv is down.
I have no picture, no sound just a black screen when i turn the power on, the power (green) light is lite up and the tv turns off by itself for like less than 30 seconds. I have tried to press as many buttons on the remote control and on the side of the TV to get any message but nothing seem to happen. Any suggestions and solutions? Thanks
make sure put the lamp door back before trying to turn it on because they have switches on them that allow the tv to turn on. If that is ok you probably have a bad ballast. Call a local tv repair shop to further diagnose the problem.
i believe that this set is built with fans to cool down the inside, check if the fans are running slow, because that could be your problem since you get both sound and picture. i think that's what it is.
Since the set is less than 1 year old, it should still be under warranty. Request warranty service.
The noise you are hearing is probably arcing inside the set on the power supply board. Continuing to attempt to turn on the set will only make things worse. Please request warranty service as this is unusual for a TV that new.
You possibly have a cracked solder joint in the vertical circuit, possible the vertical Ic itself. You'll have to remove the board and look carefully at the soldered connection of the vertical circuit and see if any are ring cracked. Some soldering should fix the problem. If you let the problem go too long the heat these cracks generate will eventaully short the vertical Ic..
I had a similar problem where my 61" Samsung DLP was turning itself off very frequently I had resolved to try replacing the bulb. I called a local TV repair place to see if they had my buld in stock. The guy I spoke to actually told me how to fix my problem! There is a little blue switch behind the bulb access door. The inside of the door has a little piece that presses the switch down. The switch is supposed to work correctly weather the switch is in the up or down position but samsung forgot to take expansion from heat into account. If the switch is held in the upper position by the door and the plastic expands to a certain point, it triggers the set to shut off. This does not occur of the switch is held in the lower position. What you need to do is take the access door off and put it back on by sliding it into position from above. That will hold the switch in the down position, eliminating the problem. My set has not **** itself off ever since.
I had the same exact problem.
I removed the bulb and cleaned it. There is a small screen at the top of the bulb and it was covered with dust. Once it was cleaned I replaced the bulb and it solved the problem.
Thanks to those who posted the solutions
