I think the best thing you could do is to Get all the drivers http://support.acer-euro.com/drivers/notebook/as_5670.html ready. After that, reinstall a fresh copy of OS and install the drivers again.

Under the operating system you want click on "Drivers and utilities" so it expands, then click on "Orbicam 944", this will begin the download. You may notice a information bar pop up in Internet Explorer informing you that a file wants to be downloaded and asking you to accept

i know your problem. even if you change the inverter it will not work. the real problem of your notebook is vga memory or video memory. use hot air to resolder your memory. trust me!

You laptop can connect to any television or display device with S-video input through the S-video/TV-out (NTSC/PAL) port, located on the right side of the laptop (this is the round whitish port located between the two USB ports and the ventilation slots.
The computer has also an external display (VGA) port by which the laptop can be connected to a display device (e.g., external monitor, LCD projector).This is the port on the right side nearest the end of the computer.
