ADC to DVI adapter Power supply?

[Retro Rider]

I have an ADC to DVI adapter that I think is broken. It seems to cut out and glitch at random times, and the USB works (at first), then it seems to die. I've done some reading, and I saw an ifixit post where they say that every 2 years the power supplies die (post). I'm pretty sure its the adapter because I've tried it with different Studio displays and it seems to do the same thing. I was wondering if anyone knows if the power supply or something else is to blame and how to fix it. Also, how do you disassemble the adapter?

I don't know how to fix, however, I have a replacement if you can't.  I discussed it here:

You have the white unit with the power supply inline with the cable? I have a different type of adapter that uses a kind of Y-cable and a Cube power supply (Dr. Bott DVIator). Not that it's likely to help you any, since Cube power supplies are usually kind of scarce, but maybe you'll get lucky and find a set.
