Hi, Can anyone recognise or diagnose this problem we are having with our Samsung LA32A450 LCD TV? It wont power up, no power on lights. Switch on side of TV wont turn on. Remote wont power it up. This may be the key ..... My wife tells me that my 3yo was playing with the remote & the buttons on the side of the TV Would there be any strange combination of buttons pressed that could have rendered it useless? Could close proximity remote activation have caused anything?

Hi g_coopster,
Samsung LA32A450 LCD TV wont power up or no power on lights that indicated that no power line.
First of all, check the power line, cable AC cord is it installed properly, change ac cord if necessary. If you experience with electrical tool such as Volt meter, try it to measure the ac voltage from power line.
Or open your rear cover of unit, there are 2 board with difference color brown PCB (IP Board) and Greend PCB (main board). Check fuse on power board, if broken that may cause your problem. Change with the same type as labeled on it. But becareful, if after you change and try plug the power line in than broken again, thats mean power board have sort circuit.
My suggestions, try steps above and if it file, change power PCB block. You can buy it on Samsung cervice center.
Good luck.

Your power board is defective.
