im trying to use LGP32-11P for powering a few led lights, a pi, and a small 12 volt audio amp. for the life of me i cant get this supply to turn on. ive tried tieing the inverter on and power on pins to ground individually and together. no joy. this typically works, and the supply worked before i pulled it from a broken tv.any assistance would be very appreciated.

that work?

From cold side ground, (north of the dotted line) find a standby voltage on one of the 2 connectors, P201 or P203. May be 5V-12V, but will always be present when just plugged in. Connect that through a 150? resistor to Power On.
BUT, it may not stay on since CCFLs for the backlight are not connected...
YMMV

im not getting standby voltages from anything on this board. which seeing as it was just working is disappointing.

aha! got it. it must have been dropped. the fuse was bad.

Good!
Was going to suggest you hook it back up to the TV, but your picture shows we're a bit beyond that point... ^-^

the screen and many parts of that tv were kicked in. somebody moved and didn't want to take it with them so they kicked it. i see them all of the time around my apartment
What a waste
