That's funny that you just posted this. I stripped down a 75 inch Samsung and got 10 strips out of it. I want to use them as under cabinet lighting and so I was trying to figure out what the voltage was. I used a 12 volt wall wart power supply, but that didn't even make it blink. I looked up on the internet and found out it takes quite a bit of voltage. one fella had a variable power supply and found out it took about 48 volts to drive them. I assume that the power board varies the voltage to change the intensity. I'm going to try a laptop power supply with 48 volts.
