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?
There are a few different versions of the display cable depending on the LCD supplier. Sounds like you got the wrong cable. Open up the system and locate the LCD info and give that to your supplier so you get the correct cable. Also post the info here and we can lookup the part number for the correct cable (your old cable should also have the P/N on it as well).
