You could get cut getting the sticky plastic label off. It's possible that while opening up the white case you will get a nasty pinch. Your adapter may be possessed and decide to bite you! There are voltages inside this little box that have unknown locations, so please be careful and make sure this adapter is unplugged before you attempt to rip it apart!
Now, a quick excerpt from Wikipedia that explains the ADC monitor connector -
The Apple Display Connector (ADC) is a proprietary modification of the DVI connector that combines analog and digital video signals, USB, and power all in one cable. Apple used ADC for its LCD-based Apple Cinema Displays and their final CRT displays, before deciding to use standard DVI connectors on later models.
First implemented in the July 2000 Power Mac G4 and G4 Cube, ADC disappeared from displays in June 2004 when Apple introduced the aluminum-clad 20", 23", and 30" Apple Cinema Displays, which feature separate DVI, USB and FireWire connectors, and their own power supplies.
The ADC was still standard on the Power Mac G5 until April 2005, when new models meant the only remaining Apple product with an ADC interface was the single processor Power Mac G5 introduced in October 2004. This single processor Power Mac G5 was discontinued soon after in June 2005.
Once Apple decided to abandon the ADC connector around 2005, many people were stuck with really nice Apple Studio Displays that couldn't be used with a standard DVI connector.
Apple's solution to this was to sell an adapter that allowed you to connect your ADC monitor to a DVI output - so you could use it with newer Apple computers, as well as using it with a PC.
This 'instructable' is more like a 'take apart', since I won't be doing any modifications - just ripping it apart to see what's inside.
I did quite a few online searches and could not find any pictures of the internal components of the A1006 adapter, so I figured - why not put that information on instructables?!?
This was listed in the newspaper, and for a very reasonable price - they are still getting around $75 - $100 for them on ebay.
The person told me that they were having to futz with the power cord - plugging it in and out of the adapter slowly, only halfway, etc. to get it to work. Once working, it was fine until a power flicker or maybe a bump to the adapter.
When I went to pick it up the gentleman had decided that he didn't want to charge me anything for it because there was a good possibility that it wouldn't work. I was happy with that, and agreed that if I got it working I would send him some $$.
After lots of futzing with the power cord, trying a different cord, trying with a PC (a little easier to shut down and not cause any problems if you let the POST screen go for a bit), I could not get it to work. It sounded like a loose connection with the power plug on the adapter, but after the following dis-assembly I couldn't find anything obviously fried.
I'm now looking for more information on the power supply inside this adapter, so if you can add to the collective, please do!
