Question about Dell E773C 17" CRT Monitor
Periodically, the contrast menu will appear on the screen by itself. When the exit button is pushed, the contrast menu will disappear for a few moments, only to reappear again. This will usually happen 4-6 times in a row, and then the problem goes away for a while. Is this a known problem?
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.

I believe what you have here is simply the contrast button being stuck. Hope this helps
