I have an old(er) LG 49LJ550M-UB that I'm looking to convert into a light source/audio player.
The only issue I'm currently experiencing is that I can't get the LED's to stay on permanently. I still have the intact LCD panel and have fiddled with all of the settings trying to get the LEDs to stay on with no luck. In lieu of that working, I'm hoping to trick the power board into keeping the LED's on. I think that I've found the correct signal that I need to send, >3V to the PDIM pin on the P201 connector on the power board. But I'm not sure where to grab...
