(home made lightbox) Keeping backlight on - which pins to bridge on monitor psu board
thought id seek a bit of pro advice from the forums for my first post as im totally drawing blanks on this one!.
i am trying to finish my custom lightbox made from an old hanns.g hh281 monitor. at the moment, when powered on, the backlight turns on then off after a few seconds as no pc signal is being received.
i have taken a picture of the connector to the main board as i cannot figure out which 2 pins to bridge to keep the ccfl backlights on :-(
i was guessing one of the ground pin and the on/off would work but didnt want to mess this up on the first go .
any input would be a godsend!
thanks all!

I am trying to do the same thing. Unlike you, I decided to risk it and try bridging pins randomly till it works.
I found that bridging ON/OFF and either of the +5V pins with a 10K resistor makes the backlight glow as soon as power is connected. I tried with a 40K resistor, and it had the same effect. However, with both these resistors:
(a) The backlight was glowing very dim
(b) The backlight continued to glow for 5-6 seconds after I disconnected the power
Please note, I have NO idea what I'm doing. I really hope someone who does can answer this. Here's a picture of my monitor's PSU board pins.
