I used to repair monitor from Dell. There are 4 screws for rear panel and no screw for 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). 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. The lamps should be located horizontally along the screen edge top and bottom. you might not see the whole lamps after opening the screen's back cover but you can pull it out from the lamp case. It has 2 electric wires connected to the end of the lamps.

Your problem may not be a lamp issue at all..it might be a power board problem.

Why won't it turn on?


While it is on, shine a bright flashlight on an angle across the surface away from you. Can you see any faint images on the screen. If yes, then possibly the back lit lamp / board needs to be replaced.

How to replace the lamp in a Mini Maglite


The Mini Maglite is a durable, compact flashlight. If your Mini Maglite stopped working, check or replace its two AA batteries first, and if that doesn't fix it, you'll probably need to replace the lamp. You can order replacement lamps in packs of two online, or you may be able to find them locally in a hardware store.

To replace the lamp in a Mini Maglite:

1. Unscrew the bottom of the flashlight. (Hold the flashlight with the head facing down so that the batteries don't fall out.)
2. Remove the batteries.
3. Unscrew the flashlight head from the barrel.
4. The lamp is mounted into the flashlight on two prongs; gently pull up on the lamp to remove it.
5. Install the new lamp by lining the prongs up with the two holes and slowly inserting it fully.
6. Screw the flashlight head back on.
7. Reinsert the batteries.
8. Screw the base back on.

When you've finished, turn the flashlight on (by turning the lens cover or the head counter-clockwise) to verify that the new lamp works. If the light doesn't come on, take the flashlight apart again and check to make sure the lamp is installed correctly and fully. Since the lamps come in packs of two, if you can't get the first lamp to work, try the second lamp in the pack. If that lamp doesn't work either, check your batteries and make sure the lens cover and head are both screwed on all the way.

Hi. I have a InFocus dp2000x. It has no lamp. I try with a flashlight in the lamp chamber (the flashlight is battery operated) When I turn on the projector with a vga or video input, the power led start...


Hi,
Projectors are designed to be used with a lamp and will turn off when there isn't one present. You would have to purchase a new lamp to use the projector.

Pc works fine but has black screen. if you hold a flashlight up to it you can see the screen a little.


If this is the case, then the only problem with your computer is the backlight on the monitor. You can have the backlight replaced. If you are not technically skilled, I would highly recommend that you take it to an authorized service center to do the repair.

Thank you for using FixYa.

My ibm a21m turns on with the little light as well but nothing happens the screen is blank the hard drive powers up still nothing need help please


You may have a faulty inverter or defective CCFL lamp. A faulty CCFL lamp may have the following symptom: Screen flashes on and off or displays reddish pink hue. Picture stays on in red and slowly be come normal. Picture flickering and/or with dim display or appear black. Picture flickers on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replace the CCFL lamp.
To determine if the video card or the LCD is faulty, connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight or a faulty inverter that supplies high voltage to the CCFL lamp. Usually the CCFL lamp fails before the inverter.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

If you see a very dim image or black screen or flicking image on the LCD screen it means you have a backlight problem.

Connect an external monitor to your laptop and power it up, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight.

Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.

Monitor wont turn on, green power light on


Hi you can inspect that what's wrong with your monitors. After you turned it on and the screen went black, you have to check that if you can see the image on the screen or not by shining a flashlight into the screen, not directly but find the best angle to the screen and take a look very closely. If you can see the icons or any image, there will be a minor problem. This is because of the lamps inside screen. Some of them were broken and it is very easy to replace. If you cannot see anything on the screen, there'll be some problems with inverter board. If you have soldering tool and want to fix it by yourself, check the caps first. It may cause this problem. Some caps might show leaking or burn spot on the board because of too high temp. If you don't have soldering tool, you better go get a technician to do so. Hope this help!! If anything I can help you with, feel free to let me know.
Thank you,
