The best solution for dead Apple Cinema Display power adapter, detailed HowTo

I've got a hold on 23" Apple Cinema display recently, but with the faulty power supply. If you had the same problem, you probably now that it is a royal pain to get these today since Apple is not manufacturing those any more. If you look on the Ebay, you can find used ones with no guarantee.
Having seen this , i decided to take things into my own hands and use my high school electronics knowledge to fix this issue.
There is a workaround suggested on the web to use switching power supply, an external box with exposed wiring, which I did not like so I look at the available universal laptop power supplies that would be able to supply ~90W, 24V and 3.7-4A required for this project. I was lucky to find one that fits the description, made by Prudent Way with manually selectable voltage. Current was rate up to 6A and power was 90W. I just wanted to give it a bit of breathing room and I went with 145~150W version with the same other specs.
This method is the best since it does not involve invasive cutting of the monitor's proprietary video cable, but rather modification of the power supply cable. This ensures that not only power is working but USB is in sync as well. Other methods worked but USB was not usable.

DISCLAIMER: I am not responsible for any damage that this method may cause to you or your property, so there you have it, use at your own risk!

1. Cut carefully original dead power supply along seam line and expose PCB of the DC power connector, and cut all 3 wires. Leave them longer except the one leading to the resistor on the far left on the photo, that one we don't need. The PS was a tough nut to crack but it is possible with careful use of small saw.

See the DC power connector at the left side, the one monitor gets plugged in? Cut all 3 wires, black and red from the small PCB leading to the PS, and black one connected to ground on the AC connector. Now you have small board with the DC connector on it along with additional circuitry to sync the USB.

2. Look at the Prudent Way DC cable end, it is a female connector with 2 holes labelled + and -. Stick in red wire (after removing the insulation, approximately 0.5 cm) from the small PCB we took out front he dead Apple power supply to + and black to - respectively (red is + and black is -). Use electrical tape to secure the connections and isolate any static electricity that may cause issues. Make sure that all is well insulated.

3. Power on the power supply and adjust the voltage to 24V, the other settings are automatically selected for you. Make sure it is memorized by the PS (see Prudent Way documentation).

Plug in the power cable to the power supply and hope for the best. Power on your Mac beast. Again, I am not responsible for any damage you may cause using this method. It worked for me and since approved LCD PS was used it should be fine with everybody else.

4. Final look

The monitor works great, power supply is cooler than the original and USB ports work like charm.

Here we are, 7 years after.... this is now a OS X blog. I actually got rid of the Windows from 2007 and haven't looked back since. After Powermac G5 and Powerbook G4 came Mac Pro 8 core and Macbook Pro 15" with 2x23" Apple Cinema Displays.
More to come.

OS X86

Been tinkering with so called OS X86 for a while now. Besides my 2 laptops this is my main interest, making my PC run OS X flawlessly but not a cheap Mac replacement but rather as e tech experiment. SO far everything works except the Quartz Extreme on my Radeon X800GTO. For more info and I bet that this will lead you toward getting a Mac is on www.insanelymac.com where you can find tons of info about the latest Mac news. Google OS X86 wiki for hardware info.

1st entry: Barcelona arrives

Finally, after so many months of delays Barcelona is among us. So far, preliminary benchmarks are up and interesting facts are cropping up. AMD as always has great ideas but given the current financial outlook it is hard to see them getting profitable quickly which they need to urgently, otherwise....
Four cores pumping variable clock rates in order to save energy and innovative bus technology will give it definitive advantage over current dual core Opterons but Xeon will likely regain performance crown in November when Intel moves to 45nm Penryn core. One thing I know: I'd like to have a couple of these babies revving in my box. :)
