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 -.


Here - http://cgi.ebay.com/NEW-AC-Universal-Adapter-Power-Charger-Laptop-NoteBook-/270607615828?pt=Laptop_Adapters_Chargers&hash=item3f01788754


Only thing we have to be conserned about with this power adapter is, will it fit? do we need to modify the wires that come from the adapter so that it fits to the display, and what is the polarity on the display panels power plug. 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.

I am trying to find - 545e59b.jpg


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.

When you get inside the monitor, you need to note where the power plug is, where the wires go, you need to remove the old power plug and route the wires inside the display from that hole then following the power plug and its wires, remove the old plug and take note of which one is + and which one is -, then solder the - wire from the power adapter to that connection point and then solder the + wire to the + connection point.



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.

No power


Have tried checking the power cables or changing it? How about the power source also? If yes? There might be problem on the built in power supply of the monitor.

Sounds like your power supply capacitors are causing the power supply to shut down. Or you have a short in the monitor loading the power supply. You should try a different power supply.

Fist place to check will be the power supply, look for bad caps with bulging tops, check to see if you do have 12vdc feeding the back light inverter circuits, see example of failed monitors (90% are due to bad caps): http://s807.photobucket.com/home/budm/allalbums

Yes the adapter must have an output of 12vdc AND rated for a least 4.0A output!

My Medion TFT 15" LCD monitor (several years old) now just cycles when I try to turn it on (get green power light, screen comes on for an instant, then screen and green power light go off, and cycles...


I ended up taking it to MicroCenter and their free Tech Support guy determined that the monitor was definitely bad (not the external AC adaptor). I was able to buy a relatively cheap replacement.
Incidentally, the monitor may have gone due to an electrical storm or when my PC's power supply went. At about the same time as this problem, the PC wouldn't power on... the power light would blink and I'd get clicking. The Tech Support guy checked the power supply output of one of my internal connectors and it was definitely bad. I replaced the 250W power supply with a Thermaltake 430W one (I wanted to add another drive and a couple more cards, so increasing the load) and voila "it lives again".
