Question about Samsung LN40A450 LCD TV
It's sort of a solution, but I work in a computer shop and got this screen in yesterday. I looked at it closely and it's actually the backlight that died. I pulled it apart and found that three of the 820uF/20V capacitors had swollen up. If you replace them then you should be fine, but I went for a different approach and took the inverter board from a laptop and put the in the screen and used an external power supply. It's a bit dark but it works fine now.

check the power inverter on the power strip. also check the caps on the board and if any of those caps have a round top it is bad and needs to be replaced. i hope this helps.
