This may not be a problem with the inverter , but a problem with the video card. Try hooking up another monitor to you laptop the see if the video card is putting out signal. If you get signal then you can try to fix the power supply for the screen. If you get no signal then you may have a video card failure and have to replace or repair it. There are many videos on you tube on laptop repairs, check these out and it will give you a better idea of the skills and tools necessary to take apart the laptop and perform the repairs. Hope this helps you with your problem.

White screen but plugin monitor works. is it the screen?


http://support.acer.com/acerpanam/notebook/0000/Acer/Aspire5100/Aspire5100sp2.shtml

http://www.laptopscreen.com/English/model/Acer/ASPIRE~5100/

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 ]

http://www.laptops-we-r.com/prestashop/aspire-5100-parts/109-acer-


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?

http://www.amazon.com/Acer-Aspire-5100-Inverter-PK070005U00/dp/B005F1N5O2

http://www.fonerbooks.com/test.htm

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 ]

Acer aspire laptop 3680 backlight turns off after it has been on for a good while leaving screen black.


The inverter is over heating or going bad. It is cheaper to replace the inverter than buy a new notebook.

here is the website for the part.

I would have a tech install the part.

My lcd screen on my acer aspire 3680 loks like a negative


You only replace the inverter board when there is no light coming from it. E.g. in a dark room you cannot see any light from the screen. But it sounds very mutch like a cable rather than the whole LCD try and get a cable first it will be LOTS cheaper.
Hope this helps

ACER 3680 2022 LCD SCREEN PROBLEMS


It may not be a problem with the lcd.

This is most likely a problem in the video card of the laptop.
but you can test it out, if you plugin a extra screen to the laptop to see if the white dots come to the other monitor aswell.

If you see white dots in both of the screens this means the video card is about to fail. and would need to be replaced.

If you don't see any white dots on the external screen then the problem is in the lcd.

You can call bestbuy they should give you another phone number to call for repairs / parts.

No light on screen of acer extensa 4620 4605 PC notebook


This is a problem I have experienced with my HP laptop as well. I found some info on this and was told that it was the inverter. I managed to fix this by finding the inverter and, unplugging both ends of it and plugging it back in. This fixed the problem and a week later its still working!

The inverter is usually located at the bottom of the screen. To access it you need to unscrew the screws around the screen. This will involve removing the plastic covers and simply unscrewing them.

Once you have removed the plastic cover from around the screen, you should see the inverter at the bottom. Re-seat the connectors, and see if this fixes it. If not, replace with inverter. The site below is an example of where you can buy one.

This may help you with the process

CHANGING INVERTER


Always make sure the power cable is unplugged and the battery is removed before stating. The inverter is usually always right beneath the screen on most notebooks. Peel off the rubber pads or plastic covers around your screen to reveal the screws. Once all the screws are out you should be able to pull the plastic bezel off the screen. Sometimes seems stuck so pull hard but not hard enough to break it. The inverter is the little board below the LCD, usually has a cable pluged in at both ends and a few little screws holding it in. Remove the screws, unplug the cables. Reverse the process and hopefully your backlight will come on.
