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.

AG,
This is a problem with the LCD screen. You’ll need a new screen or use it as is. The problem is NOT related to the inverter. I’m sure 100%.

This entry was helpful. Would you take a few moments to look at the URL posted below.
It includes pics from my Acer Aspire 5100-301. It has now developed an annoying sporadic green or blue strip on the far right side of the screen.
Is this an inverter issue or just a simple screen replacement?

I hate my Acer. But I do need a little help, if you don’t mind! The backlight sometimes works, sometimes not. I’m guessing there is a poor connection. Hoping it’s not a solder situation. I have a 3680 Aspire, which has two additional hard plugs at the top of the bezel, in between the screen latches.
What should I be looking for? How do I get those additional plugs out? I’m not so concerned about scratching the surface, Just don’t want to kill the beast. I’m kind of desperate, as I teach my kids through cyber school, and my main system, an HP laptop has to go in for a motherboard recall. UGH!
Thank you SO MUCH for any help you can provide!

jon,
I’m not familiar with that model but taking apart the display panel is very similar for most laptops.
Not really. Just be gentle with the video cable connectors, do not touch the controller board (logic board) on the back of the LCD screen, be gentle with the inverter board. Other than that, it’s relatively easy to replace the screen.

is it relitavley easy to replace the screen on a 6920 g? and is there much you can break when you take the cover off?

ramalingam,
I will as soon as I get one for repair.
By the way, the display disassembly steps will be very similar for most laptops.
1. Remove rubbers seals found on the display bezel.
2. Remove screws found under the rubbers seals.
3. Remove the bezel and you are inside.
