You can try the monitor on another computer to verify it is the monitor and not the display card at fault.

I'm assuming this is an LCD monitor. If you are sure the monitor is the problem, then your monitor's display driver circuit is probably getting close to failing. When one of the three colors (red, green, blue) becomes intermittent, the screen takes on the hue of the working colors. In your case it sounds like the blue is starting to fail.

A repair technician may be able to replace the circuit.

Black screen on computer monitor


Here is the link for the E151FPb monitor manual.
Since you email your question you have access to get this manual and print it. The manual shows the Auto set button, the contrast control button and a monitor reset feature.

Unfortunately you have to do each of these blind. Follow the instruction given, push buttons smartly, wait a few seconds for any action to take place, then follow the next instruction.

Good luck.

Contrast window pops up and dims the screen.


You are not alone. I have a Viewsonic monitor that does exactly the same thing. Wasn't sure if it was the monitor or a "bug".

Contrast button stuck? driver issue? etc?


It is a hardware problem and needs a replacement. Also try to unpress/release it by tapping lightly on the monitor. If you feel it is a driver problem then go to Start->Control Panel->System->Hardware->Device Manager->Monitor. Remove this monitor and from Action in the Menu select San for New HW. the monitor drivers will be loaded and you can then reboot.

The contract button seems to be stuck. Try pressing the button hard a few times and see if it helps. If the contract button still keeps poping up and it may be a physical problem with the button there.

Brightness/contrast window pops up and scrolls through fast


The up/down button on your flat panel is stuck. Please contact Dell Technical Support to have the monitor replaced if its still within warranty.

The Contrast screen pops on all the time


It looks like your UP button contact is demaged.
SOLUTION is to insert a piece from your business card mostly above the button to adjust it down or up. It works fine.

Menu keeps popping up


Never a good idea to clean with any spray cleaner. The cleaner does get down in the button bar and cause corrosion and shorting along ribbon cable. Use screen wipes for computer monitors only on TV's and any type of monitors. You can remove the back of the case. And remove the button board and clean with a cue tip and alcohol along ribbon cable.

I had a simalar problem with my Dell 2001FP. The issue is that there is false triggering of the switch; you need to open the front panel, and electrically remove the swictch from the circuit by: 1) analyze the circuit; its usally pretty simple - a voltage drop circuit. 2) disable the switch by either removing it with a solder gun or, simply by using a sharp blade and cutting the PCB track leading it to it, as I did.(much easier - and reversible!) Fixed my problem.
