Screen not working, black
Hi,
My imac A1207 20" screen is just black.
In a previous replacement of the cdrom I brake the siplzy cable and it worked badly, showing horizontal lines and a 256 color display.
After replacing the cable, I just dont have any image. I can only note that #1, 2 and #3 leds are grren solid and when I put the imac to sleep the #3 led goes off while the other two keeps on.
I really need this not so new machine to work. Any clue?
Is this a good question?

really need help here... connecting an external pc screen doesn't give me any image, just the 'no video' signal. I dunno if in order to use an external monitor I have to do anything more than just connect it.

Ouch! thats not good! - IF you can't get an external display working then the GPU unit is damaged.

Dunno how can happend, the inverser cables are ok as I can see, and just when realising the display cable was broken the image where bad but it was a image... I think there is also some back light....

I'm having the same problem. with 2 separate iMac 20" desktops. neither one will put a display up, but the iMac recognized that an eternal monitor is connected.
