In this guide I will remove the LCD screen and FL inverter board from an Acer Aspire 3620. The guide will work for other Acer Aspire models. If it works for your, please mention the model number in the comments below.
You’ll find my first disassembly guide for the same Acer Aspire 3620 in the previous post where I explained how to remove the motherboard and clean the cooling module.
Let’s start taking it apart.
Step 1.
You’ll find four rubber plugs in four corners of the LCD screen bezel. Remove these plugs with a sharp object and glue them somewhere on the bezel so they don’t get lost. Remove four screws hidden under the rubber plugs.
Step 2.
Start separating the screen bezel with your fingers. I found it’s easier to separate the bezel if you start from the top.
Continue separating the bezel. Be careful with the display latch, it has to stay attached to the screen cover.
Finally, remove the LCD screen bezel.
Step 3.
You’ll find the screen inverter board also known as FL inverter mounted below the LCD screen. Remove two screws securing the inverter board.
Step 4.
In order to remove the inverter board, you’ll have to unplug two cables.
The black cable on the left side is connected to the motherboard. It supplyis power to the inverter board from the motherboard.
The cable one the righ side is connected to the backlight lamp inside the LCD screen.
Now you can replace the inverter board with a new one if needed.
I’m not going to remove the LCD screen because I’m taking it apart just for this guide.
Step 5.
Remove two screws securing the LCD screen brackets to the hinges.
Now you can separate the LCD screen assembly from the cover and access the back side of the screen.
In order to remove the LCD screen assembly you’ll have to unplug the video cable first.
After the video cable is unplugged, you can remove the LCD screen assembly (screen and mounting brackets).
If you are replacing the screen with a new one, you’ll have to transfer mounting brackets to the new screen. You can find a new screen for your Acer Asprie 3620 (and any other Acer laptop) here.

I just replaced rear cover on my Acer 3620 because hinges had broken cover, now I have no back lighting. I never removed screen or inverter (connectors were never disconnected) I just laid them both on the keyboard while i worked. Any idea of what I have done.

nelixs,
I search on ebay and it looks like they sell same screen for the following models: ACER ASPIRE 5050 3050 3600 3620 3680.
It means you can use Aspire 3620 LCD screen without replacing the cable.

So that you’re not wasting you’re money: make sure that you have 6V of power to the screen before you replace it. That will let you know if you actually need a new screen or a new whatever else. Obviously if the screen is cracked to shit like mine is because I threw it against the wall, then you need a new screen! Hope it helps.

Your directions are great! Thanks for helping us diyers. Your guide can also apply to an Acer Aspire 6935. The difference is the lower bezal where it attaches to by the hinges. It was a real pain and very tricky.

Did you replace the original screen because it was cracked?
“Yes I replaced a cracked screen.”
Did you get backlight on the cracked screen?
“I did the very first time I took it apart, but when I put it back together no light on the cracked screen. So when I put the new one in I thought it would be fine, but no backlight.”
Check the video cable connections. Maybe your new screen is not plugged correctly.
“I checked and rechecked the connections. I don’t think that is it, unless I am not clicking them in properly. But like I said, I am getting picture, just seems to be no backlight.”
I also took the inverter out while the screen was on and nothing changed. I didn’t lose any picture. It was like it didn’t even matter that I took the inverter out. Super weird! Any ideas on why I can see Windows, icons, wallpaper, etc. but why the backlight doesn’t seem to be working?!? Thanks.

Dallas,
Did you get any image on the cracked screen?
If yes, what happens if you connect the cracked screen back to the laptop. Does it still show image?
If the new screen shows no image but the original one does, it’s possible your new screen is defective. Just a guess.
