I have a Mac ibook notebook computer, Model A1104, Ser # UV2522PPN4R, 14 inch display. The display no longer displays anything, just blank screen.
I was wondering how I would be able to connect a VGA monitor to it through the DVI jack, I have a DVI to VGA adapter. But it seems that in order to connect the external monitor, you must do this on the computer. So I cannot get the connection to work. My VGA just stays blank and off.
When I turn it on, the computer does it startup sound and the system seems to be booting up.
Is there any key combinations I can do to get the external monitor to work?
Thanks for any help and info you can give me. Lee J.

Re: Display screen does not work
First of all, try a restart with the monitor attached. Secondly try going to the system preferences panel- It should be in the dock - the icon with the apple and the light switch. Try to "detect displays" and see if it comes up in the menu and if the screen responds..

First make sure your screen brightness is not turned down. If not, and the computer can still turn on, chances are it's the logic board or display that has gone out. Your computer will need to be repaired by a specialist.
F1 and F2 on the keyboard make the backlight go dim or get brighter.
connect an external display to the computer if the issue doesn't show up on the external display it's the LCD inverter board that will need to be replaced.
There's a couple things you can do that may help. Try opening the display to different positiions. Sometimes the display cable inside gets damaged and you may be able to position the display just right to allow the cable to work. This is a long shot but it's woth a try. The other thing is to press the fn key and press the display brightness control to see if there's any difference in brightness. The lcd may be ok, but you may be able to replace the inverter for the display (if you think you can open up and do a bit of disassembly and reassembly). If you want help with this let me know. The displays, inverters, and cables inside are all replaceable and it's considerably less expensive than purchasing a new one. There's several companies that can do the repairs. One is powerbookmedic (dot com). they also have repair how-to guides and videos... if you feel comfortable with do-it-yourself... There's plenty of parts available for the G4...it's a great machine.
Hi If you are still faced with this problem..... Possibly the video card has gone in the unit. The original screen on the laptop may have had an blown inverter which would not stop the funcioning of the external display. However for the external disply to stop working would suggest the video card. Before going this far have you checked to see if there is power to the external monitor? Have you tried the monitor on another computer? If the monitor works with another computer you can be certain there is more wrong with your poor old iBook. You will need to take it in to be looked at.
