    I have an old G4 (not eMac though) And I have had the same problem. I used the monitor and it worked 2 times and then I too got the blinking blue light only. When you first boot up the Mac the "analog" "digital" goes back and forth, but it does that with my laptop also. The monitor works fine with my laptop (digital) but not the desktop (analog). Anyway, after it did not come back on I tried unplugging the card and re-inserting it. Checked all the cables and such and came to the conclusion that my card went bad. So I replaced the card with the same on that was in there and again... it worked 2 times and now won't come on again!!! Help! The computer works great when you can see what your doing, but I can't keep replacing cards! It's a ATI rage 128 if that helps.

    do you have the drivers installed for it?

    did it work before and is not working now?

I found that the analog cable that came with the monitor was a cheap thin grade cable. My boss at work gave me an old thicker cable and when I hooked that up I have had no more problems. Get your self a better thicker cable.

And yes, it did work a couple of times before it went blank with both cards. I did not install a driver as this was a hand-me-down Mac and I just plugged the monitor in and it worked. It didn't think to install a driver since I had to have the monitor to see what I was doing and it worked.

Blinking power light, but nothing happens.

It could be that your RAM needs to be reseated i.e. the RAM could have come loose and just needs to be taken out and put back in again. Hope this helps.

Computer and monitor will not turn. blinking power light 3x

This is just an off-chance thing. The three lights could indicate a failed or badly seated memory chip.
Turn the Mac off and remove the side. Remove the perspex panel and then remove the grey plastic panel containing the 2 large fans (it just pulls out towards you).
You now have access to the RAM sticks. Use the illustrations on the inside of the Aluminium door to identify the sticks and so that you can remove and re-seat them. Refit the fans and the perspex panel and see if the mac will start up. If not, you may have to try extra RAM (depending on how much you have installed). These macs have their RAM installed in matching pairs so if you have only 2 stick in your Mac then you need to get 2 more in order to eliminate the first 2.
Report back if that helps.

Power light goes out but power remains thru the m-board fan runs

you need to replace the power supply. The fan sound is the fan for the power supply and not the computer. for cheap parts or used goto headgap's. They know what you need and probably even help you replace it yourself.

Resolution issue Acer V223w

Hi, I'm sorry to hear you are having trouble....
THis is a tricky one. My first step would be to connect another screen to your G5 and connect your V223w to another Mac... Are you able to do this, do you have access to another system, could even be a PC ( in the worst case )
Ideally, having 2 screens connected to your G5 would be the best situation.
THis way, with one working screen, you can attempt to modify the resolution and refresh rates on the V223w from the good screen, be sure to activate screen mirroring, otherwise you will not have access to the other window of monitors system preferences.
If you can get two monitors connected and mirroring is not an option, then either your monitor is KAPUT or the video card secondary port is KAPUT, try switching the port of the card your displays are connected to. I think they are both DVI ports. If the opposite screen is now working, then you know it's the port on the video card.
Hope this will get you through it.

''Twain is Missing'' keeps coming up - can't scan from printer

Download appzapper , you get 5 free goes with it. Drag your old HP software onto it and it will find all the hidden files. Zap it. Hopefully this will have delete all HP related files.

Download the latest files from HP for your Mac. If you do this first AppZapper will delete this as well, so you'll only have to download it again.

So basically, you're deleting all the old files for HP Deskjet 5510 printer and installing all new ones.
