This can be a problem from the lcd display too.because if you noticed on a peripherical device as the tv it doesnt show erors..and the ptint screen same..if it was the video card...these errors would contiinue to appear..so it usrelly is  a display problem..try to udjust the settings..if it will not work consult a specialized acer service..
bye

Have damaged screen extensa 4220, can i connect laptop to tv ? which cable do i need?


well u can connect it to a computer monitor or to TV by using this product

follow this link to see it and all the required cables are included in the product

http://sewelldirect.com/pc-to-tv.asp

but my advice is if u want to connect ur laptop to an old TV (Not flat and doesn't have a high resolution) don't connect to it and buy a new LCD screen to ur laptop , so just connect ur laptop to any TV which is flat or LCD and have a high reolution cause u may face a problem in colors and resolution

good luck

LCD Screen is normal on one half and blank on the other


Most likely. You can check the cable connection to the motherboard and check the cabel where it goes thru the hinge assy for wear, but what you describe is indicative of a hardware failure of the LCD

Also connect an external monitor, see if it shows full screen, if it does, and reseating the cable has no effect, check Ebay for a replacement LCD

How to get a new screen for the Acer Extensa 4220-2148 Notebook Laptop 1.83GHz 1GB DDR2 ?


Ebay is the best place to try but as your notebook might not be listed, do a google search for it then look at compatible screens i.e. yours might fit several other acers or a dell etc so take the details and check for those models on ebay.

My acer 9300 when switched on shows a blank screen (black with some faint white back ground) but the process of starting windows goes normally coz i can view this when connected to a monitor whats a miss ?...


If you see a very dim image or black screen or flicking image on the LCD screen it means you have a backlight problem.

Connect an external monitor to your laptop and power it up, 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.

Acer extensa 4220 wireless problem


I'm not sure if you tried hitting the appropriate key on your keyboard to initialize your wireless network. Check your manual to see which key it is, it is not automatic. Also, make sure you have a wireless card. Click on start>all programs>accessories>system tools>system it will give you a list of all your hardware, Look for 802.11b/g that is the wirless.
