Question about Dell UltraSharp 1905FP LCD Monitor

3 Answers

Power button stuck

I HAD two Dell 1905FP monitors. When I came in this morning I pushed the power buttons. The left one came on but the right one did not. The left monitor's button make a little click when you push it but the right does not. It appears to be stuck. The right was the primary so I had to switch cables to do anything. I would like to set it for only one monitor but the control panel window opens way over on the other monitor which isn't there. I do not know if rebooting with only one montior plugged in will eliminate the dual monitor settings. If someone could tell me how to get the case open I think I should be able to unstick the button.

    Basically, just pry carefully? Up a little on the front piece then out on the side piece all around. And be careful about the short wire connecting to the piece you're taking off.
    I need better "screwdrivers," first try I didn't pry hard enough to move anything and messed up the plastic around the slot real bad. If anyone has some advice on proper prying it would be very helpful.
    But it turns out the IT guy was able to send it back on a warranty (hopefully no one notices the gouges).

I have fixed three of these power supplies for Dell 1905FP. Once you get the power supply out like stated above. There are three capacitors the have bulges. Replace them with the exact same Farad rating and your finished. This is a common fault of these monitors.

The power button on my Dell 1905FP monitor failed with the power turned off. Following the advice posted by Guest: pried the trim panel loose using a couple of small screw drivers starting with the small slots just under the power button. As guest states in his posting, the connecting wire is very short, but does provide enough room to access the buttons lying behind the trim panel. With this access, was then able to press the power button back to the "on" position. Snapped the trim panel back into place. Monitor now works fine, though the only way to turn the power off is to unplug the power cord.

I had the same problem. To get to the power button you just have to remove the front trim panel that the button is attached to. There is a small slot on the bottom of the pannel near the power buttom. I inserted a very small screwdriver and pried the front corner up then very carefully I went around the perimeter with the screwdriver and released the snap hooks by gently prying the silver side trim panel away from the front trim panel. It's not hard but you have to be gentle so as not to break a hook or mar the trim. Once you have the front trim panel loosened there is a wire which connects the four buttons on the front to the monitor. It's very short so don't drop the front trim panel.

My Dell 1905FP 19 monitor went black & green power light flickers

It sound like a short circuit. I had this problem with 1907FP model. It had an USB port on the monitor which got damaged and it was shortening to the groung. In your case it might be a bad internal power supply board.

My dell 1905FP power button flashes green and will not turn off, the screen is black.


This is a common indication of a failure in the power supply. There are parts called capacitors that are used in the filter section of the power supply, when they go out the power supply can't properly turn on so you get no picture and a flashing power light. Here is a picture of the power supply board with the problem filter capacitors circled in yellow and below the picture in a link to a repair guide with details dis-assemble and repair instruction along with parts list for the Dell 1905FP and 1907FP models.
