Question about Dell UltraSharp 2407WFP 24" LCD Monitor

1 Answer

How do I remove the back cover on a Dell 2407 WFP?

I feel that the backlight is overheating. After the first 20 minutes or so, the screen goes black. The lights are all on. If I turn the monitor off and back on it will immediately go black again. If I let it set for a few minutes, it will stay on for a while, until it heats up again. I am out of warranty and very dissapointed in Dell. Thanks

Hi, I can't offer you a fix for your overheat problem, but here's how to get into the 2407WFP!

Place the monitor face down on the bench. Remove the four screws from the back.
Turn the monitor over and lay on its back. With your fingertips gently ease the front bezel from the glass, starting far away from the buttons and not putting too much pressure on the glass. It comes away with a series of clicks.
I managed this easily, but if your fingers aren't strong enough you could use a lever (you MUST spread the load on the glass so as not to break it, and avoid doing too much damage to the plastic of the bezel!)
Work your way all the way round snapping the bezel from the front, but don't completely remove it as this will strain the ribbon cable from the buttons.
Lift the screen and rest it on one edge, and you will find the back starts to come free from the insides.
Carefully lay it flat on its bezel again and lift the main rear casing away.

You are in! To get at all the boards:
Undo the 8 gold-coloured screws from around the edge of the central metal cover (not the four which hold the VESA-mount in place) and all three covers can then be removed to expose the backlight inverter board, power supply board (very similar to the one in the 2405FPW, see related articles if the PSU is your problem), main controller, and USBhub/card reader PCB.

Hope that helps you - now to find out why it's bust!

    Uhhh.... that monitor is disassembled far easier with a shim pop around the outside of the bezel, going at the screen from the glass side is folly..http://www.youtube.com/watch?v=SZE_R8CPt...

This is a backlight problem. The picture is there but there is no light from behind the LCD screen. It could be due to faulty capacitors, which are easy to replace. It could be a faulty Inverter transformer, which is harder to fix but he backlight controller board can usually be replaced at a reasonable price. If you have soldering experience you may be able to replace the faulty capacitors - look for capacitors with bulging tops.
Repalcing the inverter board in a job for someone with electronics experience. You can buy a universal inverter board for about £15 to £20 from e-bay.
20 inch monitors can be bought for about £100 to £150 so you need to decide whether it is economical to repair.

Hi the sceen goes black when it is switched on for ten minutes if I switch it off for a few minutes the sceen comes back on. It will then shut off again after a few minutes. Thanks Alan


This is due to the inverter for the backlight, or the backlight itself going bad. You are going to be better off replacing the screen unless you are handy with electronics.

My Dell 1905fp Ultrasharp was coming on intermittently for a little bit and then it would not power up at all.


You said your monitor will be on for little bit and then would not power up anymore... there are two possible reasons why this problem occur..

1. You need to check if the high voltage ballast transformer of your backlight inverter is about to be burned... the transformer is overheating..that's why you experience the monitor working for a couple of minutes and then it will shut off until the transformer cool down again and then it will be ready to work again...

2. You need to check the power supply section for possible loose connections and blown capacitors.. the ballast transformer has direct effect on power supply section.. when there is overheating transformer,,, the supply current from the power supply section becomes unstable.. and will not be able to supply the remaining good working ballast transformer.

In case you do not know, the ballast transformer generates high voltage for the backlight inverter to work..The backlight inverter is the light source that is responsible for the image display of your screen...If the ballast transformer is not working or if the backlight is busted then the only thing that you will see in your screen is black....

Please be advise that if you don't have the knowledge, the proper skills and the right tools to open the back cover of your monitor and replace its part...don't risk it...

Otherwise, bring your unit to a credible technician and avail of warranty if there is any.....


Much appreciated if you rate this help...thanks...

How to open dell monitor cover model E207WFPc


Remove the Stand, Remove the 4 Screws from behind the spot where the stand connects to, then take a flat ended object such as a butter knife or a sharp knife, and unclip the black face. then the screen comes right apart, this solution is also the same for the 20xx-30xx Dell WFP Models.

Laptop LCD goes black after a few seconds


Hello,

Yes, The pink tint is an indication that the backlight is failing. Now the backlight is basically dead, the best way to get back going is to do an Ebay search for your model laptop and get a new screen. Most screens can be purchased for around $50.00 - $70.00 and they are very easy to swap. Email me if you need more info.

Dell Ultrasharp 2407wfp Going dark?


I have seen this happen, and it gets to the point where the overheating will cause the backlight to entirely **** out, and then you've got a pretty nice paper weight. I would definately give Dell a call on this one to ensure it is under warranty. If this is the case they should easily be able to identify it as an issue with the backlight system and get you a replacement rather quickly.
If this part is not under warranty, well you can part-piece fix it, but it is a pain.

Screen blacking out.


Hi, I used to fix a monitor from Dell. There are 4 screws at the back of rear panel and no screw at front frame. If there is no visible screw, you have to look for "capped" screw holes (little covers that fit flush with the case to hide the screws). If you don't see these neither, this must be a tension fit case. So, face the screen up and look for "rectangular hole" on the side edge (usually at the bottom edge of the screen). This will be a challenge to open without breaking it. You'll need a very thin flat screw driver and wedge it into that narrow rectangular hole. You can use any prybar if you don't have screw driver. It is not too deep. You may stab something important inside and pry it. Once it starts to spread, start sliding it along the seem and you should feel the tension tabs start "popping" open. Continue to work your way around until it's off.

For the metal plate that shields the back of the screen, There are some screws you have to deal with. Those screws are at the power and screen connectors.



Thank you,
Tan

Monitor goes off and on


Yes your backlight is going bad! This is common with an LCD monitor! There are no guarantees with these new items! Sorry I hope that this helps! When a backlight goes bad it will generate enough light to display an image, but it will not hold that charge for very long, it varies based on the manufacturer who sells the Montior!
