http://www.tvrepairinfo.com/ Converting my broken LCD TV into a well illuminated sign seemed like a good way to convert a TV not worth repairing into something useful. To make this conversion simply remove the LCD Display, and make you sign out of plexiglass to fit over your back light. Since most power supplies require a turn on signal from the main board to stay lit, you will nee to take the 3.3 of 5 volt standby power from your power supply and feed it to your inverter BL on terminal.. You will also need to feed your stand by power supply output to your power on terminal on the power supply. Sometimes it's called PS ON or PWR ON. in this case I fed the standby power supply output through a 1000 ohm resistor to play it safe. Some manufacturers may have different ways to force the power supply to come on when the main board is absent, but in this case the 1000 ohm resistor seemed to work fine.
