Hello everybody here on the board. Just stumbled into this place and really like it.
I hope my question goes into the right place, please correct me if not...
I have a defective iMac G5 1st Gen. Motherboard needs to be replaced, but i don't really know if I should again invest 400 Euro in a new one, since this is the second time it blew up!
I really loved the display of my iMac, so the obvious question is, if it's possible to mod it into an external display. The basic idea would be to throw out all stuff i don't need anymore (CPU, HDD and so on) and solder on a DVI-Plug at the right spot.
Has anybody an idea if this is possible? Is the display controller part the main unit, or can it in some way be separated?
If somebody has any experience with the internal structure of the iMac G5 (1,8 GHz) and how everything is wired together, any suggestions would be highly appreciated.
Seems to be the infamous Power-Supply-Bug of the iMac G5 Rev A. Computer will not boot or , in fact, do anything.
I checked resetting SMU (without effect.) Diagnose LED 1 is on (telling me I have power). When I try to turn the imac on, sometimes LED's 2&3 will flicker shortly (according to Apple this means the power-supply is out of order), but -also very strange- sometimes will not flicker at all ( which is, acc. to Apple, even worse: Logic Board needs to be replaced). So I don't really know.
My mac's 3 and a half years old now, so Apple wont do it for free. Sad thing, I really liked this Computer...
this question has been asked before, and IIRC, the problem is that the display is soldered onto the main board of the imac. So, without the pin-out configuration, which I am not sure there is one available on the net, you are going to have a pretty hard time doing this.
I think other users were interested in putting other hardware in the care, maybe a mac mini or something...
Have a look around and do some searching into the pin-out configuration. If you can figure this out then you might be able to make the conversion.
Best of luck and welcome to MacMod!

For the most part it is not possible to use a bare LCD screen as a second monitor. The motherboard talks to the screen directly, and in order to use it with DVI/vga you would need a controller board to convert the signal into the same language as the screen. If you look hard enough you can usually get a circuit (there is some official name for it) that will let you use a bare LCD as an external screen. But by the time you buy the circuit you might as well just buy an LCD monitor. they are so cheap now anyway.
Wow, what a response, thanks everybody. If I understand that last link right, an mac-mini to imac conversion is not an option also. Well, it's really very unfortunate, but I'm not too disappointed about that, as it's somehow exactly what I expected. But what really p... me off is the fact, that the second board blew up, after it was replaced about 1 and a half year before, due to the mentioned power bug in the imac g5 Rev A. Seems Apple had a problem with the replacement-boards as well. But i dont want to get too off-topic, so thanks again to everybody for the suggestions and help. greetings from germany , slim.tim
This is the definitive answer. It can't be done in anything approaching an economically feasible manner.
I often point people to the "Holy Grail" as a starting point. In one respect, it is correct, in another, quite not. The issue with the holy grail is that people were always searching for it, and could never find it.
This store sells LCD controller boards, panels, inverters and all the cables you could ever want. They have close to a hundred different LCD cables, and they're all about USD$10 each. They will program the controller boards for you, and in most cases, you'll get out of it for under USD$150.
But, like the Grail, there is a downside, or two. Firstly, you have to go to Japan to see it. Secondly, you have to be able to speak passable Japanese, as they don't speak very much english at all.
