E151FPB flat screen monitor goes white

Question

I was wondering if anyone had ever received any answers about their flat screen E151FPB monitors going white.  I think it is odd that all of us who are having problems bought them within the same three months.   Please let me know if Dell ever did any thing to remedy the situation because now my monitor doesnt work at all!  Thanks!

I had the same thing happen a couple of weeks ago.   I called support.  They had me check connections and some lights on the back of the tower,  and determined the monitor was back and sent me another one.   I called on Thursday night before the 4th of July weekend and had my replacement by Tuesday.   All i had to do was send the old one back.

How long had it been since you purchased your monitor?

well, this is not what i'd call a fix.. more like an 'interesting development' - your results may vary. i have been having the selfsame e151fpb flatscreen monitor going white problem. this has always been momentarily fixed by turning the monitor off, then back on again after a few minutes. i began to notice that the amount of 'off' time needed varied, and seemed to be proportional to the amount of 'on' time you'd get before another incident. now i know nothing about these monitors, but the symptoms are pretty consistent with overheating.   bottom line is: i now have a tabletop fan blowing at the back of my monitor, and the problem has completely disappeared. plus it's hot and humid here and i don't mind the breeze that sneaks around the side.   obviously not a permanent solution, but it may allow you to discuss your monitor problem and shop for a new (CRT!) one with fewer hassles.

I've got a E151FPB with the white screen problem too. Since I'm way out of warranty, I took the thing apart trying to find the problem. After checking a few things, I finally started cold-soaking the large video board (there's two: the brown one is the large one) and narrowed it down to a large capacitor (I think it's a capacitor), or a component directly adjacent to this capacitor, right in the center of the brown board, directly to the right of a large silver heat sink assembly (looking at the back of the monitor right side up). Cold-soaking this capacitor made the monitor work again, and if I heated it back up, it went white again. I did the cold-soak, heat up cycle a few times in an effort to narrow down exactly which component was the problem. Now I can't get the monitor to go white again. It's working just fine; in fact I'm looking at it right now as I type this message. I've had it on continously for about 2 hours now; it used to go white in much less time than this. If it breaks again, I'll let you know.

I re-soldered the component described in the last post, and it seems to have fixed the problem.  I've been using the monitor for a few days now, and it has not gone white, so thanks for the repair info.  When I hit the two solder joints with the iron, I observed the solder basically disappearing into the cavity, which tells me the joint only had solder on the surface and was hollow in the cavity - no wonder there were problems.  Hopefully Benq has fixed the manufacturing problems which caused this.  Anyway, thanks again for the info!
