Watch posting two posts for the same problem, and not putting the Full information in the second one, as you did on the first one.
As in this one.
Original question is why is the screen Pink.
An LCD screen cannot produce light,http://solutions.3m.com/wps/portal/3M/en_US/NA_Optical/Systems/BehindTheScenes/Optics101/
(Click on the monitor icon )
Therefore an LCD screen needs an additional light source.
A Backlight is the additional light source.
A Backlight can be a CCFL, (Or two of them), or a series of LED's.
(Light Emitting Diode)
A CCFL is a Cold Cathode Fluorescent Lamp. (Bulb)
Similar to Fluorescent lighting used in homes, and businesses, but on a MUCH smaller scale.
Average thickness of the bulb is 2mm. That is a little more than 1/16th of an Inch.
Average length is almost as long, as the LCD screen is in height.
LCD screens for the Aspire 5535 series of Notebook PC's, show either CCFL backlighting, or LED backlighting.
My Aspire 5535 uses LED backlighting.
A laptop using CCFL for backlighting uses a screen Inverter.
General rule for LED backlighting is that No screen Inverter is used.
In reality it depends on the laptop. When LED backlighting first came out, a screen Inverter was used. As time progressed no screen Inverter is used.
A screen Inverter is used to convert the power (Electricity), from the laptop; for the LCD screen, and Backlight.
You need to check if the problem is the graphics chipset, or Video Cable, or inside the Display Assembly.
(Inside the Display Assembly: Screen Inverter IF used / LCD screen)
The Switch Cover is the plastic cover above the Keyboard, and below the LCD screen. Has the Power On button, and status indicator LED lights in it.
Acer's term for Switch Cover is Middle Cover.
The Video Cable is LCD Cable.
The LCD screen is LCD Panel.
The Video Cable connects to the motherboard, in an area under the Middle Cover.
(To the right of the Left Hinge)
It then routes through the left Hinge, and up into the Display Assembly. (LCD Module)
From there a separate small cable. comes off the main Video Cable, and connects to the screen Inverter.
IF a screen Inverter is used.
The main portion of the Video Cable, then connects to the back of the LCD screen.
Just due to repeated normal opening, and closing of the laptop; the Video Cable may become pinched, and pulled on.
This can lead to loose connections at motherboard side, and/or screen Inverter, and/or LCD screen side.
A loose Video Cable connection can cause what you are seeing.
Also due to being pulled on the Video Cable may receive damage.
The procedure is to remove ALL power, remove the Middle Cover, and PHYSICALLY check to make sure the motherboard side connection of the Video Cable, is plugged in tightly.
Visual inspection alone will NOT do.
[Middle Cover is supposed to be just that. A Cover.
If it has the Power Button Board, and LED indicator lights attached to it, try to lay it aside when tightening the motherboard connection, of Video Cable.
This way you do not have to reattach it's wires, to check if motherboard connection was the problem ]
Once the motherboard side of the Video Cable is checked for tightness, the power can be reinstalled; and laptop turned on, and checked.
(AC adapter [ Charger ] and Battery)
Tightening motherboard connection of Video Cable does no good?
On to the LCD screen side, and screen Inverter. (IF used)
The plastic frame in front of the LCD screen is the Display Bezel.
Acer? LCD Bezel.
The Display Bezel also has the Hinge Covers attached to it.
I do not believe the Display Assembly (LCD Module) has to be removed, in order to remove the Display Bezel. (LCD Bezel)
There are 4 Philips head screws to remove from the Display Bezel.
These are under Screw Covers.
One in each corner;
Top Left, Top Right, Bottom Left, and Bottom Right.
The Screw Covers are made of synthetic rubber, or plastic.
They are gently pried up from the bottom edge of them.
I use a computer pick.
If you are careful you can reuse them. I LIGHTLY stick them to the Display Bezel for safekeeping.
(They like to stick to Everything! Your fingers, the computer pick, and passing satellites)
They have a type of rubber cement that holds them on. If needed you can apply a TINY dab of rubber cement with a toothpick.
Remove the 4 screws.
The Display Bezel has TABS going along the perimeter of it's inside edges.
These Tabs snap into matching LATCHES on the Display Cover.
The Display Bezel is also flexible.
I cover the LCD screen for protection, with a piece of thick construction paper cut to just fit the inside edges, of the Display Bezel.
Then slightly lift the INSIDE edge, of the Middle, of the Right side of the Display Bezel.
Come to the middle/right of the Display Bezel, and inside/LCD screen side.
Lift the Display Bezel up a bit. Can;t slide a fingertip in?
Move over. You are at a Tab/Latch.
With a fingertip underneath, use the other hand, and slide a fingertip under also.
Slide down until you reach a Tab/Latch. It should pop open. SNAP!
Sounds like you are breaking something.
Keep moving down towards the Bottom. Keep popping the Tabs/Latches loose. Move towards the Left side.
Once the Display Bezel has popped most of the way loose, it should then come all the way off.
IF a screen Inverter is used, it should be mounted at the bottom of the LCD screen. It's a small green circuit board. One small cable will come from the Video Cable, and plug into it. (At the top is the Webcam, IF used)
The LCD screen itself is an assembly. It is composed of layers. You saw this in the 3M video.
The layers are held in the factory set alignment, by a metal Screen Frame. Looks like a picture frame.
There are two Brackets.One Bracket on each side of the LCD Screen Frame.
The LCD screen, and Brackets are removed as one unit.
HOWEVER, the LCD screen is NOT to be removed all the way. It is just tilted forward enough at the Top, to access the Video Cable connection on back of the LCD screen.
LCD screen connection checked, and this does no good, then remove the Video Cable.
The Video Cable needs to be checked for Continuity.
Every wire needs to be checked to see if electricity goes through.
If not this means there is a stretched/broken wire.
Check with a multimeter set to OHM's. (1K)
Check every wire. Also have an assistant gently wiggle the middle of the Video Cable. An intermittent reading on the multimeter indicates a broken wire.
No multimeter available? Suggest take the Video Cable down to the nearest small computer shop, and have the resident tech check it for Continuity. Should only be a few bucks.
The Video Cable connections, and condition; MUST be checked before going on. You MUST rule out the Video Cable as the problem, before proceeding.
Video Cable checks OK?
On to the screen Inverter IF USED.
To test a screen Inverter requires a Sensitive multimeter.
Read fairly expensive,http://www.fonerbooks.com/test.htm
Due to this, and the ease of accessing to replace, plus the usually low cost; the screen Inverter is just replaced.
Video Cable connections checked for tightness, Video Cable condition checked, screen Inverter replaced, and problem still exists; problem is the LCD screen.
If NO screen Inverter is used, problem is LCD screen.
This is a link to THE Service Manual, (Free),http://www.tim.id.au/blog/tims-laptop-service-manuals/#toc-acer
Go to the 'paragraph' that starts with Aspire 1200. (1200 in Blue)
Drop down to the 7th line. Begins with 5310G in Blue.
Scroll across, and click on the blue -> 5535
This is a PDF file. The computer you are using now has Adobe Reader on it, which uses PDF files.
After you click on the file name (5535) it may take up to 30 seconds, before the first page comes up.
There is also a way to save a copy to the computer you are using now. This way you can copy it off to a CD disk, and have it for safekeeping.
You can also delete it from the computer you downloaded it on, and save harddrive space. (AFTER checking to make sure your copy is good)
If you do not know how, and wish to; post back in a Comment.
The page numbers of the Adobe Reader, and the page numbers of the Service Manual; do NOT match.
When I refer to a page number it is for the Adobe Reader.
The Adobe Reader page number box is at the Top. It is to the Right of the Down Arrow.
You can use the Down Arrow to go page by page, to the page you want; or you can do this if you know the page you want,
1) Put your mouse cursor in the Adobe Reader page number box, at Top. Left-click once.
(Everything in page number box is now highlighted in Blue)
2) Type the page number.
3) Press the Enter key.

This LCD screen replacement pictorial guide is NOT for an Aspire 5535. It is for an Aspire 5745G.
Procedures are CLOSE. Thought a pictorial guide may help.
