Question about Dell Latitude D620 Notebook

1 Answer

Changeable parts for the screen

Hi! I have a broken dell latitude d620. The backlight has gone in the screen and I want to change it. I need to find a screen inverter and it have been very hard to find one for this model. Inverters cannot be bought, only together with the screens. I wonder which models are compatible with my screen inverter. I mean computer models. Or is there screens for other computer models which can be used for my dell.

Go online to Screen Tec and visit their web site. You can find a referral for inverters. Inverters are sold without screens on a regular basis. If you are still having a problem check out www.oceansidecomputers.com/laptops.htm

Dell d620 sCREEN GOES BLACK AFTER WINDOWS SCREEN COMES UP. None of the normal Fn keystrokes help. i never make it to the login screen. Help?


If your laptop appears to boot up and the hard disk LED flashes, then the problem is probably a back light fault. This can be a faulty inverter or a faulty CCFL lamp. Please click on this link and follow my instructions to identify the fault and possible fix :- http://www.fixya.com/support/r3598095-faulty_laptop_lcd_screen

Where can i find the process to change a D410 inverter


If the screen on your laptop is dimming or not working at all, the fault may lie in the Dell Latitude D410 Inverter --the device that powers the screen's backlight. Replacing an Dell Latitude D410 LCD inverter will require some finesse, but you do not need a technical background. If you are comfortable with opening up your laptop, then this is a do-it-yourself project.
1. Unplug your laptop and remove the battery pack.
2. Locate the rubber screw covers around your laptop screen. There are typically four, but some models may have more.
3. Remove the screw covers. Take care not to lose any. They pop off and, if you are not careful, could go flying.
4. Place your fingers between the front bezel (the plastic piece around the LCD screen) and the screen. Gently work your way around the screen to remove the front bezel and expose the screen assembly.
5. Remove the inverter from the screen assembly. It is held on by tape in most models. In some models the Dell Latitude D410 Inverter may be right at the bottom of the screen assembly, below the actual LCD. Other models have the Dell Latitude D410 LCD inverter behind the screen. To disassemble the screen, you will need to either unscrew the screen from its metal holder, or just lift the screen out to expose the inverter.
6. Disconnect the wires leading from the Dell Latitude D410 Inverter. One wire goes to the backlight, while the other goes to the video card.
7. Look on the back of the Dell Latitude D410 LCD inverter for a model number or serial number. Having this exact number will make it easier to order a replacement.
8. Connect the video wire and the backlight wire into the new inverter and affix it using the tape that held the original in place. If you do not have that tape anymore, or it has lost its adhesiveness, you can buy more from computer parts retailers.
9. Put the screen back in place if you need to, and snap the front bezel back on.
10. Screw the front bezel screws back in, and place the screw covers back in place.

The backlight won't turn on but occasionally will flicker.


Suggest you replace the Inverter. A Backlight goes out all at once.
90% of the time the Inverter is the hardware part at fault.

[ An LCD screen cannot produce enough light by itself.
A Backlight is used to supply the needed extra lighting.
A Backlight is a CCFL.
Cold Cathode Fluorescent Lamp.
Similar to Fluorescent lighting used in homes, and businesses, but on a much smaller scale

An Inverter is used to required power for the LCD screen, and the Backlight.
Boosts power up for the LCD screen, brings it down for the Backlight.

Dell Support > Latitude D600 Notebook PC > Service Manual

http://support.dell.com/support/edocs/systems/latd600/en/sm/index.htm

Replacing an Inverter is a simple job. Replacing a Backlight is not.
The Backlight is located within the LCD screen assembly.

The metal frame of the LCD screen assembly is removed along the edge where the Backlight is located, to access replacing the Backlight.

In the above list for Service Manual, click on > Display Assembly and Display Latch.

This information shows you where the Inverter is located on a Dell Latitude D620 Notebook PC.
The Latitude D620 is part of the Latitude D600 series of Notebook PC's.

http://www.insidemylaptop.com/remove-replace-lcd-screen-dell-latitude-d620-laptop/

Just one place from a quick search, that sells Inverters for a Latitude D600 series Notebook PC,

http://www.parts-people.com/index.php?action=item&id=2895

MATCH the part number listed that they have, to the part number on your Inverter.
You have to have THE correct Inverter.

the batteries eventually wear out and quit taking a charge. You can run the system without a battery with no ill effects. replacements are about $100 for a new battery

I dropped my laptop, it works but the backlight doesn't. Ive got a dell Latitude D620 how can i repair it at home


Below is a link that gives you an illustrated view of the disassembly of your laptop. It be that the wire from the video cable has popped out of the inverter. When you remove the bezel from the lcd panel, check the plug connections on the inverter before changing the inverter out.

Dell Latitude D620, Black Screen/Power On


It is the backlight! That laptop uses a fluorescent lamp. It is bad.
If you look carefully at the screen, you will see the Windows desktop (or whatebver you are running). It just needs to be lit up.... from the back. Tel them to replace the LCd screen or replace the lamp.

Hope this helps!

Dell Latitude D620 no display on main screen!!


Hi,
If you have already replaced the LCD inverter cable and still the problem is there . You also told that the display is working fine when connected to the external monitor. This mean the Video controller on the motherboard is fine. This lead us to the conclusion that you would have replace the whole LCD assembly and not the inverter cable alone.


Thanks for using fixya

Dell Latitude d620 display problem


Sounds like your computer has just bit the dust, do your self a favor and purchase a new one. This time buy an XP, it might be a little bit more, but you get what you pay for.

Dell Latitude D620 Gray Screen


I don't know about that particular laptop but it sounds like a loose connection between mainboard and screen plus a bad inverter (regulates and supplies voltage to the actual screen from the main power source). Laptops typically have the inverter hidden somewhere in the frame that surrounds the actual lcd screen. Sometimes this regulator is part of a small circuit board, sometimes it is not (I suppose it might be part of the actual lcd in some cases, but i've never seen that). I would investigate things further in that direction and just hope your lcd itself isnt bad.

Blank Laptop Screen


Either the LCD inverter or the LCD or, at the very least, the backlight in the LCD, is faulty. You will need to replace either your LCD inverter or the screen itself.
