but you could try to connect another machine to the G5 and log onto your G5 from that one.
Hi everyone. Sorry in advance for the lengthy message! I've got a problem with my 2005 Ambient Light Sensor 17" G5 iMac (non-iSight). It's running 10.5.8.
When I switched it on the other day it all seemed to start up okay but the screen stayed black. I could hear the hard drive clicking and I entered my account password (blindly!) and I could tell it was loading to the Desktop. I then hit Control and Eject to bring up the Shut Down option screen, hit Return and it shut down successfully.
After doing an initial search it looked like the inverter that powers the backlight tube(s) had died, hence why the screen is black. However, I've been through the Apple support article for G5 iMacs with no video showing. I took the back off my iMac to locate the diagnostic LEDs. I re-connected the power cable and the first LED turned on. OK so far!
I switched the iMac on using the internal power button. The second LED turned on (meaning the logic board is receiving power). After that, the third LED should turn on. Mine doesn't! The third LED indicates that the logic board and LCD assembly are communicating and that the LCD is ready to receive video. Resetting the SMU didn't help either. According to the article, this means my logic board needs to be replaced!
I've just about come to terms with the fact that I now need to fork out and buy a new Mac! I'm going to get it checked by a repair guy but it seems clear that I've diagnosed the problem.
I have a recent backup, and the hard drive seems to be working fine anyway. The problem I have is that I want to "see" my iMac so I can de-authorise iTunes and Adobe CS Suite software before I transfer everything to a new Mac. How can I do this? Or can't I? Will an external monitor still work if I connect one to it? (I need to buy all the necessary cables to try it, hence why I'm asking first!)
Any help would be much appreciated.
