Moved G5 and now it wont detect the monitor?

Hello,

My father has brought his G5 to my house and when we plugged it all in and turned it on it boots ok but displays nothing on the monitor.

He does not have the keyboard or mouse with him just the tower and monitor. I have a spare apple keyboard and mouse both wireless.

We have tried different ports etc but there is no difference at all. This model has 2 DVI connections on the back.

Is there anything we can do to get the screen working?

Any help at all would be appreciated.

Cheers,

Luke.

PowerMac, Mac OS X (10.6.1)

When he unplugged it to move it , the internal backup battery may have died. That can cause a lack of video in some Mac models.

However, before we recommend a backup battery replacement or other troubleshooting, we need to clarify what Mac this is--you have conflicting information in your post: PowerMac G5 and Mac OS 10.6. No PowerMac can run mac OS 10.6 or higher.

If it is really running 10.6 he has a Mac Pro, not a G5 PowerMac--very different computers inside. A quick check visually may help: a Powermac G5 has one optical drive slot; the similarly designed early Mac Pro has two drive slots.

Hello, sorry for the late reply.

This model only has one optical drive slot.

He had a power issue with it where the screen would flicker like it wasn't getting enough power so he took it into a shop.

They ran it for a day each with 2 different power cables and found that his was not performing as it should so gave him a new one.

It worked in the shop exactly as it is plugged in now.

When you start it up it has a strange beeping sound or tone which may be the start up tone but it sounds a bit weird.

It also runs very loud.

Cheers,

Luke.

Older meanings...

Can you count the beeps or flashes?

1 beep = no RAM installed

2 beeps = incompatible RAM types

3 beeps = no good banks

4 beeps = no good boot images in the boot ROM (and/or bad sys config block)

5 beeps = processor is not usable

In addition to the beeps, on some computers the power LED will flash a corresponding number of times plus one. The LED will repeat the sequence after approximately a 5-second pause. The tones are only played once.

Note: In this case, a flash is considered to be 1/4 second or 250 ms or greater in length.
