laptop screen problem

Hi all

My laptop screen has stopped working. When its switched on, it does appear to light up, ( well the dark screen gets brighter!) and I can see a faint trapeziod image. When I waggle the screen upand down, I sometimes get broad vertical white lines, and occ a few thin coloured linesd as well. I have tried to remove the connector to the Mobo, and e=when its partially removed the screen sometimes goes very white, and sometimes I get lots of white vertical lines of varying thickness. Plugging the connector in again, screen goes darker. I have tried an external monitor, and that works fine, however, BIOS says the CMOS battery is low. Also the AC powwer supply has stopped working, so Im ruinning off battery,which is very low. Would a very low poer supply cause this. I am thinking more of the inverter or cable itself. Laptop is a satellite A10 Pro.

Thanks Guys.

 

i would get a new power adaptor

 

And what would that have to do with his LCD screen???? He already knows his power adapter isn't working.

 

Thanks Chaps. The screen did go wrong after the AC power supply stopped working, and I had been running on the battery for ages. The battery is now almost completely dead, and when connected to an external monitor, the CMOS battery is dieing as well. Could this cause the screen not to work, as I suspect the screen takes alot of power, but I am summising that it wont take as much for an external monitor, as that is externally powered, or is my thinking completely wrong
