Apple 23" ACD problems fix or replace?

get a new power brick from ebay, should solve your problems. Try for the 30" power brick, it will work and doesn't have the problems that the 20 and 23" ones have.

Leaving it disconnected for a few minutes or plugging it in and unplugging 5 times quickly has brought mine back to life.

 

If you are looking for a good replacement Dell's U2711 is on sale today for $699 at the US site

 

Hey Avro,

I know that this is a VERY old thread, but I wanted to ask you something about your configuration before the power brick was diagnosed as faulty.

I recently bought my PowerMac G5 with a 23" display and started noticing this problem recently as well. Every time it happened I wouldn't be able to get my display to come back on either after the machine was put to sleep of the display itself was sleeping. So every time I would simply change the DVI port that the display was plugged into and then unplugged it and then plugged it back in and everything would be fine.

Because of this weird "power thing" and seeing that other people were having the same issues I was wondering if it was just my configuration that caused the problem. It also had issues with recognizing usb devices connected via the ports on it.

After disconnecting the usb and FW cables from the tower and doing that crazy unplug/plug-in routine, I realized that the monitor might not be getting enough power since it was plugged into a power strip along with my PM, an external HDD, the charger for my iPad and the charger for my phone. Once I plugged the monitor directly into the outlet, all the problems went away and the monitor actually works better now than when I first got the machine.

So sorry for the long response to such an old post, but I was just curious to know exactly what you were experiencing and what you tried to before replacing the power brick. Thanks!
