Having problems with your Acer Aspire 3690-2196 Notebook ?

The screen on my acer aspire 3000 is a white almost houndstooth pattern. I tried this screen on a different acer 3000 and it worked just fine. I get a good display when I plug in a monitor. I've tried different screens and different flex cables and it's the same white pattern.


Answers :

Ok, I have reviewed your problem and have the fallowing for you to aces.
\015\012First, you said you tried this screen on a different acer 3000 and it worked just fine and that you I get a good display when using a external monitor.
\015\012So, that means the LCD is good if you have used it on other units and your problem is at your output connection point from the laptop to the LCD. Must be the connection point at the motherboard end.
\015\012If you look carefully at the underside of the LCD connection point, you may find your problem.
\015\012Please be aware, their is NO WAY I or anyone else can tell you what micro cap, diode or resistor is bad or needs to be changed, This you will need to diagnose yourself.
\015\012Good luck in your repair.
\015\012P.S. doesn't sound too hard, you have video at the external port, a known working signal and power to the LCD.
\015\012If you have a scope, trace it out.

Hi there Tom,

If you were able to hook up a monitor to your Acer laptop and gave you a good display, then the video card is properly working. The LCD of your laptop is the one that has a problem. If it is not a solid white and doesn't cover the entire screen but only portions of it, try pressing the sides of your laptop's monitor or LCD. This is most probably be caused of a loose connection between the LCD itself and the board. Personally, when I got a similar problem like yours, a workaround I did was to use a scotch tape in all corners of my monitor to firmly attach all sides of it. Then try restarting again.

If the above suggestion did not work, please let me know.
