はじめに
The Dell U2711 Monitor has a problem with unstable contacts due to corrosion. The symptom is a flickering screen. Knocking on the top of the monitor can make this symptom go away for a while, but a longer term solution is to clean the contacts.
The problem can be seen in this video:
必要な工具と部品

Lay the display on a desk with the front facing down. Best use a towel to save the desk and display from scratching.

Unscrew the four hex screws that secure the stand.

-
Starting opposite of the buttons, pry open the display bezel with a plectrum.

You have to apply some force.

Don't lift the rear panel higher than two centimeters. There are delicate flat cables on the button side which might be damaged.

Be extra careful at the buttons, you don't want to damage a cable.

Worked for me too!!! Ended up with slightly chipped casing... but who cares! i now have a as-good-as-new screen image....
So glad i found this post... was initially exploring replacing capacitors method.... but didn't start..... glad i do not need to go to that route anymore.
For anyone looking for this, you should have 1) an electrical contact cleaner and 2) TORX screwdriver!!
Once I took my U2711 apart, the connectors didn't look too corroded (in fact, they looked fine) but the process of cleaning them and unseating the connectors has fixed the flickering! Thanks a lot! took me about 15 minutes!
Took about 10 minutes .... first repair after having this monitor since they were first released ..... Back to loving my Dell again :)
