So you PHYSICALLY checked the connection of the Video Cable, TO the motherboard, TO the screen Inverter, and TO the back of the LCD screen?

Visual inspection will NOT do. If either motherboard connector, or LCD screen connector is loose, the width of this letter -> I < you won't see it, and it will affect the video signal.

The Video Cable connects to the motherboard under the Middle Cover, above the F4 and F5 key on the Keyboard. (Left edge of F4 key over to middle of F5 key)

[Middle Cover is Acer speak for Switch Cover. The cover strip above the Keyboard, and below the LCD screen ]

Click on the view to enlarge. Top left side connects to the LCD screen. Rectangular Black connector with thick round cable, at the bottom, connects to the motherboard. Small cable coming off at the bottom, connects to the screen Inverter ]

From the motherboard connector the Video Cable routes up under the left Hinge, and into the Display Assembly. It then connects to the screen Inverter, and LCD screen.

From normal opening, and closing of the laptop, repeatedly, the Video Cable may become pinched.
This can lead to loose connections.

It can also lead to damage of the Video Cable.
If the sheath of the cable shows apparent signs of damage, the tiny wires inside may be damaged also.
Stretched/Broken

This means to ENSURE that the Video Cable is NOT the problem, a continuity test needs to be performed on all of the Video Cable's wires. (OHMS)
If an economical multimeter ($5 to $12) is not available, suggestion is to take it down to the nearest 'Mom and Pop' computer store, and have them check it. Labor charge should only be a few bucks.

Video Cable checks out it's on to the screen Inverter, for the diagnoses.

[NOTE*
This diagnoses is for an Acer Aspire 5100 Notebook PC. Uses a single (1) CCFL for a Backlight, and has a screen Inverter. Laptops that use LED's for a Backlight generally do not use a screen Inverter]

Did you test the screen Inverter, or replace it?

NOTE*
Takes a sensitive multimeter. Read fairly expensive.

Primer;

An LCD screen cannot produce light by itself,

http://solutions.3m.com/wps/portal/3M/en_US/NA_Optical/Systems/BehindTheScenes/Optics101/

Click on the monitor. Suggest start out with your audio turned down ]

It 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)
The Acer Aspire 5100 Notebook PC uses a single (1) CCFL.

A CCFL is a Cold Cathode Fluorescent Lamp.
Similar to Fluorescent lighting used in homes, and businesses, but on a MUCH smaller scale.

[Average thickness is 2mm. That is a little larger than 1/16th of an Inch.
Average length is almost as long, as the LCD screen is in height,

http://www.laptoprepair101.com/laptop/2007/12/09/replace-laptop-backlight-ccfl-lamp/ ]

A screen Inverter is used to convert the power (Electricity) from the laptop, for the LCD screen, and Backlight.

90 PERCENT OF THE TIME the fault is a bad screen Inverter.

Primer over.

If the screen Inverter is good, the LCD screen is bad.
Replace.

[The LCD screen, and the screen Inverter are a MATCHED unit.
When purchasing make sure you get the correct screen Inverter, or LCD screen ]

Hi, i have an Acer 5100 and the screen is really dark... can only just make out the screen. I have tried the fn key trick with no luck. I have replaced the inverter and also the screen.... again no joy....


The fault could be a faulty video cable or connector or CCFL lamp or inverter.
Try reseating the video cable/connector that connects to the motherboard first.
If this doesn't work then to determine if you have a LCD screen, inverter or video card problem, read this and follow these instructions.
Defective CCFL backlight, it may have the following symptom: Screen flashs on red/pink and off. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickering on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp.
Connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

Blue screen flickers and goes almost completely dark... when i plug into a different monitor, everything on that monitor is clear, so i know the compputer itself is fine. How do I check for a loose


most likely inverter issue, or somewhere in between inverter and LCD, illumination bets thing to do is to take aprt the LCD frame and disconnect and reconnect all wires leading from the inverter. If that doesn't work, the replace the LCD wires and or inverter.

LCD screen looks like bad TV reception


if the display returns to normal when you press the bezel at on end means there is a bad connection to the inverter behind the bezel itself or the inverter is ready to give up the ghost.
you can attempt to dismantlethe laptop and remone the lid or in some cases just unscrew the bezel and remove the plastic cover, the inverter is at the bottom of the display you can't miss it

hope this helps

Lcd disolay has liens through it and colors are off.


If tapping the screen (on sides or back of case - not the screen itself !) affects the display it is usually loose connections either at the motherboard or behind the display where ribbon cable connects. relatively easy repair for someone who can take apart a laptop but you need the repair manual because there is a sequence that needs to be followed.

Partially dark screen


this sounds like a loose connection of your LCD back-light called the display inverter. squeezing, with your hand, the outer edge of the frame (NOT SCREEN) on the side affected could conform this.
