Re: Dell 2007WPF Flickering Off
I hope I got the right boards. I'll open it up soon again if not. I disconnected the monitor's usb ports power supply; doesn't seem to have changed much....

Re: Dell 2007WPF Flickering Off
I'll take new pictures but are they not included in the original post that has pictures attached?
How would one check the supply rails? Would I need electrical equipment for that? If so that would be out of my depth; expertise....Leave a comment:

Re: Dell 2007WPF Flickering Off
But to reiterate - The monitor on its own, powered on and with no input connected - should always display an image by itself - a bouncing "no dvi input" etc. Mine doesn't when the problems crops up. That's why I've ruled out that its a video card issue.
The problem happens whether its hooked up or not.Leave a comment:

Re: Dell 2007WPF Flickering Off
Since making the original post I have upgraded my video card - so I'm fairly sure it isn't the video card (unless its my psu not feeding enough power to the card?).
I will hook up the monitor to my macbook and ill see if the issue comes up again. Unfortunately, no second monitor atm.Leave a comment:

Re: Dell 2007WPF Flickering Off
Sorry to drag this old topic up again. So since I was last here - I replaced I took in the power inverter board and had the caps replaced. Issue came up again.
Then I bought another (used) inverter board and swapped that in. Things appeared fine (symptoms appeared briefly once or twice) until today where its reared up its head. It seems particularly bad when I'm playing a game and rather inconvenient.
A bit tight for funds atm - so I have one shot at this. What are the chances its still an issue with the...Leave a comment:

Hmm, here's a pick with lights turned off...
It doesn't look that bright in person, that's the camera but the screen is "on", no display though....Leave a comment:

Re: Dell 2007WPF Flickering Off
Sorry, I guess my wording didn't come across clear in the OP.
"The front panel buttons still glow yellow as usual, so power is still going through." That's what I meant that the monitor stays on but nothing displays on the screen.
Now since my last post, I've used the computer pretty extensively, usually 4+ hours a day without incident - until today. Screen's been "off" for the past 10 minutes now.
I was lucky enough to capture the behaviour on camera. Sorry about music......Leave a comment:

Re: Dell 2007WPF Flickering Off
I will post pics but the monitor does turn on and I can use it. It just turns off intermittently for minutes at a time and at random. It's been fine for past 5 hours for example.Leave a comment:

Re: Dell 2007WPF Flickering Off
Good news and bad news. The capacitors were replaced. All 3 big ones but the problem persists.
It's so depressing, I really thought I had it in the bag.
As you can see, monitor is on and power button is yellow (its orange when computer is off) but screen is black.
Any other ideas?
Anyone think this might be related to my PSU + GPU?...Leave a comment:

Re: Dell 2007WPF Flickering Off
Great news. Found a local who said he can fix the panel for me. I did forget to mention to use quality caps, hopefully he knows better.
Thanks everyone. Yall been awesome diagnosing this. I will update later. Now hopefully I haven't forgotten how to put it back together...Leave a comment:

Re: Dell 2007WPF Flickering Off
What brand of caps might you use? The Elite, while they did fail, that was after 8 years.Leave a comment:

Re: Dell 2007WPF Flickering Off
I'm not technical to do it on my own so I'll have to take it in to a shop / repair guy. If the cost is much higher than a replacement, do you think its safe to go with this: [url]http://www.aliexpress.com/item/Free-Shipping-Original-2007WFPB-good-test-pressure-plate-4H-L2J04-A01-6-Light-Inverter/1557005607.html[/url]
Would you go for a used part or try to scrounge for a new board?Re: Dell 2007WPF Flickering Off<br /...is much higherLast edited by aatroxed; 05-22-2014, 08:39 PM.Leave a comment:

Re: Dell 2007WPF Flickering Off
@stj Thanks, I read a few posts and knew you guys need good photos to help
Just an old nikon coolpix s6200 point and shoot I had lying around.
I took a few more picks of the inverter to make sure. If it is indeed bloated, you think a swap could fix it? Does it sound like its the source of the problem I described?
Can you visually tell if that fuse is dead?
I also included pictures where there's some glue. How would you go about removing the glue to check the components underneath?...Last edited by aatroxed; 05-22-2014, 06:18 PM.Leave a comment:

Re: Dell 2007WPF Flickering Off
No the LED on the front panel stays steady the whole time.
Are you referring to the inverter transformer in the first picture and the two small black domes near the power supply plug on the right hand side?Leave a comment:

Dell 2007WPF Flickering Off
My trusty Dell monitor is having issues and flickering off, sometimes for minutes at a time. The front panel buttons still glow yellow as usual, so power is still going through. When it flickers off and the dvi input is disconnected, it doesn't show the usual "no input signal" image so I'm pretty sure the problem is isolated to the monitor.
After much effort I managed to take it apart (I'm a newbie) but can't readily identify any points of failure.
Here we go. (I just realized the backs are useful as well. I'll those up soon if these are not clear).... -
