 Haven't successfully powered up in safe mode because you have to have the USB
 keyboard plugged in, and it won't fire up with USBs plugged in.
 
 The ATI Radeon 9600 pro has an ADC and a DVI-I port so I have only used the
 DVI 
 port.
 
 The adaptor is to allow me to use the monitor which only has a VGA port. The
 adaptor goes from the DVI-I port on the G5 to a VGA-VGA cable which runs the
 monitor.  I haven't tried a monitor which can take DVI-I. We do have one in
 the 
 house but I haven't got a DVI-I/DVI-I cable.
 
 Once I get the monitor to fire with the G5 it works well, no wobble, a choice
 of 
 monitor sizes, millions of colours etc. It also always works well with the G4
 (using just the same VGA-VGA cable) I figure some loose component on the G5
 card 
 is causing a voltage/charge drop. No bulging or leaking capacitors evident.
 
 Unfortunately I haven't got another graphics card to try so I was hoping there
 might be a dodgy component that always gives trouble and could be resoldered
 or 
 something.

Sounds like a bad dvi/vga adapter - have you checked for bent pins on
it? - try a different adapter. Cable pins can be bent too causing
intermittent contact. Also worth trying an adc/vga adapter if you can get
one

I agree, the adapter (or cable) seems a likely culprit. It seems like  
a DVI/DVI cable onto a DVI display would be optimal, but if the  
display only has VGA, I guess you're stuck with an adapter and a VGA  
cable.

ADC/VGA are rare and expensive.
Better to buy a new video card or display instead.

G5 monitor fails to fire

2011-05-11 Thread ag
My DP G5 running OSX 4.11 fails to wake up the monitor on start up. Monitor at 
the moment is a Dell flat panel but it was the same with my old Apple studio 
monitor. G5 chimes happily but monitor's amber light stays amber and fails to 
go 
green.

I use a DVI/VGA connector, and linking my G4 powerbook to the monitor fires it 
up each time so the monitor is fine.

Disconnecting all USBs and pulling power cable for ten minutes improved matters 
but now I have to power up 3-4 times or just leave it to another day.

I pulled the graphics card (ATI Radeon 9600 pro), and tested for wobbly joins, 
dust, anything else but drew a blank.

As far as I understand it the G5 is not producing a sufficient charge to wake 
the monitor from power save mode. Is there a specific component on the card 
that 
may be at fault, should I get a new card or could there be another explanation?

regards
AG

Ok.  So it's not the display.

Ok.  So it's not the power manager, cpu, or basic bus interconnects.

So it's the card slot, video card, or cable.

Check the system.log for error messages.

Try a different cable.

Try a different interface.

Try a different video card.

I don't understand? You mean you have to reboot 3 or 4 times and on  
the 3rd or 4th time the display finally works correctly?


Have you done a Safe Boot (hold the Shift key at startup)?

I'm assuming you're using a DVI/DVI cable from the G5 to the display?  
The DVI/VGA connector is an adapter you're using with a DVI/DVI  
cable so you can attach to the G4 PowerBook? If the cable that works  
with the G4 is the same cable that you're using with the G5 then the  
cable is likely good even if you're using an adapter. If it's a  
different cable, you need to try the G5 with a different cable, it  
could be a bad cable.


Intermittent video is often a bad video card, and overheating is  
always a worry with an air-cooled card like the 9600 Pro. When you  
inspected the card did you look for popped caps? Is the G5 fan unit  
working normally? Have you tried both DVI ports on the 9600 Pro?

Yes, Kris

Just to make it clear, taking into account your remarks.

The monitor will eventually fire up - might take two, three, four G5 power-ups, 
might have to leave it for hours and just sometimes it might come on 
immediately. 


Haven't successfully powered up in safe mode because you have to have the USB 
keyboard plugged in, and it won't fire up with USBs plugged in.
