You may have problem in the logic board (the right board in the first picture), bad firmware in the ROM chip, which there is not much you can do to reload the firmware. You can open it up and inspect the inside.

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.

Contrast decreases to Zero


Had the same problem recently with a Benq FP71G+. It was still under warranty so I called customer care and they sent someone who replaced the board inside that contained all the buttons. I saw that the board was very easy to remove. He just unplugged it, and plugged in the new one. And its a very small board so probably doesn't cost much in case your monitor's warranty period has expired.

Config screen keeps popping up


A friend of mine had the exact same same problem. I think I fixed it, because it has been 2 hours, without the menu popping up. You need to open the monitor:

- Place it face-down on a flat surface
- Remove the cover of the hinge by gripping it with both hands and gently squeezing and pulling.
- Undo the 4 screws and remove the stand (base)
- Undo the four screws tha hold the cover down (4 corners)
- Use a flat screwdriver to seperate the 2 halves (I used 2, a small one to lift the back, a bigger one for leverage)

You will see a small PCB, fastened by 3 screws, at the bottom (where your menu+on/off buttons are) with a ribbon connection to the screen. Next:

- Unscrew the PCB, and gently lift it out.
- Clean the microswitches and the ribbon cable connection.
- Reassemble the monitor.

To clean microswitches and the connection, I used Kontakt Video 90 spray. There must be sprays on the market where you are. It's basically an alcohol-based cleaning spray. Good for cleaning video/tape/floppy heads, CD/DVD lenses, memory modules, etc.

Good luck!

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.
