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...


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.

Sony Projection TV 60 XBR, wont turn on, blinking green light


This sounds like when the power came back on a surge went into your tv and burnt out the TVs main power supply or possibly burn out the flyback power converter on the TV main board!
(I am pretty sure it is either one of these things!)
