Question about Dell UltraSharp 2407WFP 24" LCD Monitor

Dell 2407WFP Monitor losing signal and having colored line artifacts

I have a Dell UltraSharp 2407WFPb 24 inch LCD monitor Rev A03. I run it via DVI-D at full resolution (1920x1200) in portrait mode, that is, turning the monitor on its side with 1920 pixels vertically and 1200 horizontally. I am using Windows XP, and this monitor is my second, that is, the Windows desktop is extended onto this monitor.

I have two problems, probably unrelated.

(1) My Windows settings have the monitor powering down after 10 minutes of not being used. When it goes off and I move the mouse or something to power it back on, it sometimes doesn't seem to find the signal and says "Out of range signal. Cannot display the video mode, change computer to 1920x1200@60Hz".

If I then step through the various input modes (S-Video, Composite, Component, VGA, and then DVI-D), sometimes it comes back on, and sometime not. If it doesn't come back on, I go to "Display Properties" in Windows, turn off "Extend my Windows desktop onto this screen", and then I turn it on again. So far, this procedure has always worked, and the monitor finds the signal again.

2. There are often one or more thin colored lines shooting across the screen. They would normally be horizontal (from left to right), but because I have the monitor turned on its side, they come out vertical. They start somewhere in the middle of the screen and extend across the rest of the screen. The problematic lines seem to be a function of what is being displayed. My video card is an NVIDIA GeForce 7600 GT, and the other Dell 2407WFPb Rev A00 monitor I am running never has this problem.

Many thanks.

To your problem number 1:

I would check to see what the refresh rate is on your main monitor. Especially after waking the monitor from sleep, Windows tend to forget the refresh rate settings on secondary monitor and set it to the same as your main monitor. If your main monitor is set at 75hz or something, it could cause the secondary monitor to display the "out of range" message. When you reset the "extend my desktop to this monitor" setting, it probably resets the refresh rate to 60hz again.

This can sometime be remedied by checking to see if the monitor drivers are installed correctly. A lot of times the video card driver also gets in the way. I've had a lot of experiences with ATI drivers behaving very sporadically with multi-monitor setups, where they will consistently change to "plug-n-play monitor" and thus reverting any custom setting I have.

As to your problem #2:

I've had a fair bit of experience with this as well. The fact that the line shows the same way regardless of the monitor's own tilting orientation, means the error is probably coming from the video card signal rather than the LCD panel itself. This usually is a foresight of a nVidia card that's about to break.

I've went through many, many nVidia video cards over the years. They all inevitably break over time, probably because nVidia relies strictly on third party vendors... and to stay price competitive the third party vendors cut corners wherever they can. I always get the same horizontal line error over time as you described here.

The only way to know for sure, is to get a replacement video card, borrow one from a friend if you can, and see if the same problem still comes up. It's very possible for this to show up on only one of your two monitors. Try switching the monitor output as well, to see if the line now shows up on the other monitor instead.

Can someone identify the part number of IC 651 and Q654 in my 2407WFPb Dell Monitor?


Why are people giving their opinions rather then answering the question? My monitor just died and I need to replace the main power filter cap and transistor Q654, I need the part number for transistor Q654 as I think the OP does as well.

The monitor just made a pop and no longer works. How do you take apart to check if there is a fuse


2407 is almost the same as 2408 picture I have here, just be real careful not to move the front bezel too far from the chassis or you will break the cable! Use thin flat blade screw driver or special tool as shown in the video and work around the bezel REAL SLOW!

Black screen - lights indicate receiving video signal


You will have to open it up and inspect the inside for burnt parts, bad caps, bad solder joints. This model is really delicate to take apart, must be real careful not to break the front panel ribbon cable. 2408wfp is almost the same as 2407.

Dell 2407wfpb lights on but stays blank..


Shine a bright light on the screen and press the Menu button... if you can barely see the outline of the menu come up in the middle of the screen, it means that your inverter / backlight needs to be replaced. You can get a new backlight / inverter for relatively cheap, so if you can do the repair yourself, it's worthwhile.
Otherwise it's the LCD panel itself, in which case you should go monitor shopping.

I can Fix It if I Can Find The inverter.


Cajun is an idiot. a BACKLIGHT is a pencil sized tube that provides light for the LCD. An inverter will take a small voltage and turn it into a large voltage, with a proportional decrese in current. Not nearly the same thing.

Go to LCDrepairs.com and buy the parts you need.
