Why do all A1082 Cinema Displays come without AC adapter?

    I was looking for an extra monitor to use on my Mac Pro and occasionally on my Xserve, And I decided to buy one of the old Cinema Displays because I like their design, But I noticed that all Cinema Displays A1082 that are sold on ebay, practically none of them comes with the AC adapter included, what's the reason for this? :eek:

    Did all A1082 AC adapters fail massively? :confused:

    They certainly did fail pretty frequently. These displays are so dated with their old fluorescent tube backlights I cannot imagine spending money on one of them. They're really not a good value at any price anymore.

    Yes, all of mine failed. It's usually possible to fix them by covering one of the pins that I think is used for sensing signal, but that isn't foolproof and I could see no one wanting to sell them that way.

    I already got 4th of such display and I love it. It's the best display ever and the only matte from Apple, but you have to get the right one. Most of them are scratched with some ugly colors.

    I've also suffered AC adapter failure. At first it can be fixed with pin sensing, then whole AC adapter dies, but it took almost 8 years of non-stop work.

    Current LED displays are either glossy or emits so much intensive blue light that eyes got hurt very quickly.

    Can see the end of the Earth from here
    AC adapters allegedly fail with some frequency, although I've never had one fail on me - maybe I'm just lucky.

    However, you can use this to your advantage. I had a setup with four (4) 23" ACDs that I got for peanuts because they had no power supplies. The seller had other displays with power supplies that we were able to use to verify the condition of the displays I bought so I knew they were functioning.

    There are a number of DIY threads on the Internets that show how simple it is to use a very inexpensive (under $20-$30) DC switching power supply to power the displays. Yes, you have to cut the power supply cable connector off of the display to get to the bare wires, but when you're paying $50 for a display it's no big deal. Connect the wires to the correct terminal on the power supply, and away you go!

    This is a nice setup, as it's easy to buy a single power supply to power multiple ACDs and with plenty of reserve so it's not running even close to design limits.

    Here is one of the sources I used for the information:
