E228WFP screen goes blank, TS unhelpful

E228WFP is going blank during use, generally after a number of hours. Once this happens it continues to reocurr every several minutes. This problem has happened on 2 different computers, and there is a thread on the tech forums discussing it as well.

When it happens, the computer is actively being used, and the power light stays solid green. This means it's not power saving, it's not an input problem (would result in it going yellow, or blinking green).

This problem is not resolved after a long and frustrating call, below details the reason for my dissatisfaction.

Call 1, navigate phone system, put through to an agent.. some talking in the background, call is disconnected.

Call 2, navigate phone system, Dell LCDs have no service tag so no express options are open to me. I discuss the problem with a rep, after 10 minutes I am transferred to another.

Call 2, rep 2... for 45 mintues we discuss the problem. I am asked to do many things unrelated to the problem, such as resetting to factory defaults, checking my power settings, spending time researching the specs of the computer it's connected to (a Dell E510... but has more RAM, better video card than the stock package). This rep does determine it needs to be replaced, proceeds to do relevant paperwork. He gets an error at the end of the process, im guessing because this was probably an EPP purchase or something, says he has to transfer me. He lets me know that if i provide a number to the next rep, all his notes say to replace it.

Call 2, rep 3... for just 1 hour, we confirm settings, information, he remote connects to my machine and blames my power settings (monitor turn off after 20 minutes). Does a self test and because it passes he declares multiple times that because the self test passes, it's the computer's fault and the monitor is fine.

I give up, Dell has won, I decide to just go with whatever he is saying so I can just get off the phone, nobody should have to go through this for any problem. I am told "my supervisor would like to have a word with you" as if I am in trouble.

Call 2, supervisor... just simply backs their rep, despite hearing in my own words how I was not satisfied in any way shape or form and that little/none of the troubleshooting made any sense for the problem I was describing. Just reiterated that if it happens again to please call back.

Though, tech support closes at 9pm central, and the problem only happens after a number of hours to use, so it appears unlikely we'll ever be able to call while the problem is happening.
