Samsung B2430H - 2 Seconds to Black

[caphair]

I have this Samsung monitor that's doing classic 2 seconds to black.

All caps are visibly fine, all voltages are there.

Things I've noticed:
There's a hissing sound coming from bottom of the panel.
Ripped panel apart to access lights hoping maybe bad connection/s - all in tact and solid.

I wanted to access the backlight timer pin on inverter part # FAN7317B
to short it to ground so I can see if transformer is getting warm or if one lamp in particular flickers but the data sheet didn't have a "timer" pin? Maybe labeled something else?

I also noticed, if I disconnected one lamp from the bottom connector the hissing sound goes away.

Did you pull on the wire that is solder to the end of the lamp? It sounds to me you have bad connection at the end of the lamp.
It may look normal to you.

Yes I did and there wasn't any burnt spots either, connections looked solid

Btw that link you provided didn't work, black page when clicked on.

Also, would pin 3 be the timer pin on the inverter chip?
