Hi guys

I have a Toshiba laptop.. about 3 years old.
Yesterday the screen started doing strange things.
The best way I could describe this is as below:

-- the bottom half of the monitor/screen goes very faint and has lots of white lines across it. Almost looks like what a printed piece of paper looks like, when a colour printer is running out of ink.
Its not completeley white, but has many white lines and makes the picture "fade" in that part of the screen.
Its sometimes varying degrees..i.e. not always that bad.

-- I have tried to take a screen shot of it, but it doesnt capture anything.

-- when I lightly tap the laptop, it seems to "respond" and either fix itself up or make it worse..

-- From tapping around the bottom of the laptop itself, i think the problem occurs when an area around the battery (that side anyway), is knocked or moved around. the problem is not in the screen itself.

-- I dont throw the computer around generally..it sits in one place, sometimes actualy on my lap. Hopefully i havent fried it??

-- this started two days ago and is an on and off problem... i.e. right now its fine.

-- its only the bottom half of the screen that seems to be affected, as when it happens the top looks normal and fine.


Thanks in advance! Ill try to answer any questions which may help diagnose this problem :)
