I got this 24" LCD Monitor here and have a problem with it.

When I got it, I hooked it up and I would get no input on the screen from any source (VGA/DVI/Component). The "no cable source" thing would come up with a weird flashing behind it (like the backlight flashing).

Anyway, I (stupidly) got someone to open the screen up and saw the inverter had two blown caps, so replaced them. Now when they opened the screen up, they forgot to undo a connection and it totally ripped off (see images).

As you can see, there are some pins broken completely. I managed to connect it back together, ignoring the four or five snapped pins.

So put the screen back together, not expecting much. Plugged it in and guess what, I get a picture! (Probably corrected from fixing the inverter). So I can see and run windows fine from this screen. Yet I still get the constant flashing and there are blotches around the screen with different coloured pixels.

I am thinking the blotches are appearing because of the dead pins. Now what gets me is the flashing. Is that a dead backlight or something?

To describe it in more depth: It flashes a few times a second, so its really quick. Its like a halogen dying. When it flashes, it DOESNT flash OFF, but flashes to a low brightness. When I turned the brightness from 100 down to 0, the flashing ALMOST COMPLETELY STOPPED (flashed once every minute or so).


So what I want to know:

1. Whats causing the flashing?
2. Would the funny blotches on the screen be from the pins?
3. What board is that that has been snapped (highlighted in red). What is it called? How hard are they to find?

I mean the pins dont bother me, as if worst comes to worst I can simply remove the pins completely and solder the wires straight onto the board. Its just, I dont want to do that if the flashing will still be there.

Thanks for whoever reads this post :laugh:

The LCD's brand is Sun Microsystems, but the panel and most chips on the board are made by samsung.
