Just wanted to say thanks for the detailed instructions. I was able to dis-assemble and install the new screen in about 10 minutes.

Thanks for this page. Just did a replacement on a D620. My advice to others after taking a lot of time and being petrified of screwing up my new screen:

Take your time.
Follow the pictures.
Find a safe place for the three sets of screws and rubber fastener caps (still looking for one of the screws, alas).
Remember that the mounting brackets on the sides fit UNDER the screen.
Don’t do this under the influence…
Donate (I did), even a small amount if this saved you a big fix-it bill.
Screen obtained from on ebay store laptopservicecenter. Great price, shipped right away, product looks good, new and so-far-so-good.

L T,

My back-light doesn’t come on…
You can see it boot, see the text FAINTLY and when my background pops up you can see that cause it bright green, but its all FAINT is it the actual back-light or the inverter i need to replace?

You cannot tell without testing the laptop with another known good inverter board or backlight lamp. Either one can cause this problem.
If you have to guess, try replacing the inverter board first.

OK I’m wondering if I have a inverter problem.

Hi, I have a bit of a strange problem: My LCD (D620) almost always doesn’t work; so I have it hooked up to an external monitor. However, every so often, when the laptop shifts slightly, the LCD (again, the one removed in this tutorial) flickers on briefly- for at most 10 seconds, usually 1 second or less. I removed the LCD as per your instructions, but I can’t see any unusual crimps/bad connections. (and putting it back in did not clear it up.) Do you have any suggestions?
Note: I have been unable to reliably reproduce the conditions under which the LCD flickers on.

Mip,

I see other posts regarding a ccfl lamp being the cause of the “dark screen”. This post does not mention anything about a lamp, only an inverter. I dropped mine today and the machine is working and displays but with no backlight. Do you think this is an inverter or a bulb?

If the backlight stopped working after you dropped the laptop, most likely you damaged the lamp.
Also, it’s possible that one of the cables got disconnected from the inverter board and connecting them back fix the problem, but it’s not very likely.

Richard Metzger,

Really appreciated your instructions on the removal of the LCD Screen on a Dell 620 laptop.
I am attempting to replace the inverter board (only) on my 620 but am not familiar on just how to do it for fear of messing things up. I followed your instructions and photos and proceeded with the sequence down to where I now see the inverter board but do not know how to remove it properly.

Take a look at this guide for a Dell Inspiron 6000 laptop.

I’m explaining how to remove the inverter board at the end of the guide. I think it could be similar to your laptop.

Hello:
Really appreciated your instructions on the removal of the LCD Screen on a Dell 620 laptop.
I am attempting to replace the inverter board (only) on my 620 but am not familiar on just how to do it for fear of messing things up. I followed your instructions and photos and proceeded with the sequence down to where I now see the inverter board but do not know how to remove it properly. There are wire connections on both ends and I cannot determine how to release them from their sockets.You state “Even though it looks like the inverter board is a part of the LCD screen, it is possible to remove the inverter board and replace it separately”. As stated, I am afraid to start pulling on the connectors to try to remove it so would like to know if you could furnish me with detailed instructions
and /or pictures on how to go about it properly. Sincere thanks: Richard

1xtra,

This procedure is similar for a Dell Latitude D830 ?

This procedure is similar for most Dell laptops.
