Hello,
While I can't locate the exact powersupply used in this model - it is no longer available unfortunately. But you may use a universal power adapter, in the end it does not matter what device is supplying the power aslong as it is 12v and around 3A. And that the polary is right. + connected on + and - connected on -.

There should be a small icon on the display, or if you have the old power adapter on its bottom you will find the polarity icon.
here is what the icon will look like and it notes if the center is positive or negative.
The polarity has to be correct. 3.0A is not so important, it won't ruin the display if it gives more or less. but if the polarity is wrong it will ruin the display.
So you just need to be extra carefull when finding out the polarity that you get it correct.
If none of the adapters fit the display then I'd recommend to take apart the display, you would also have to cut the wires coming from the power adapter and then solder them to the power plug connections inside the display.
Taking the display apart...
Remove all the screws from the display, remove the stand, check for hidden screws under labels, soft objects etc.
After that the casing is only held in place with plastic clips, insert a
plastic stick, case opening tool, flat screw driver or your fingernails
in the cracks in the plastic, or openings, and move it up and down. The
clips start opening, you need to go around the display, etc until you
get it apart, then it will again have screws on top of the power supply
and mainboard cover etc. very simple from there on.
Here is a quick video of a guy taking apart his monitor, i don't
recommend the exact method of "hammering" the screen open, but you see
where the display cover opens up.

Put the display back together and that is it, make sure the power adapter is set on 12V, plug in and your good to go.
