Question about Samsung LN-S3251D 32 in. LCD HDTV
I have a new Samsung LE32B450 TV. When the power cable is plugged in, the TV makes a starting sound, but the picture appears only for 1-2 seconds, and then goes off. I can not set the TV because there is nothing on the screen. What is the problem? and how can i fix it ???

Try replacing C51, a 10 microfarad 16v. surface mount electrolytic. It's near IC23 on the upper center of the board.
This part had high ESR on a couple of sets I serviced which
kept the power supply from starting.

SOURCE: samsung tv turning off by itself
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.

is the picture clear when on? if yes, does the screen go black after a few seconds. if yes, sounds like you need a back light inverter!
