I have a strange problem with my advent laptop.

I have just changed the LCD screen. The screen works fine until I switch the cooling fan on via the button next to the keyboard. The screen then becomes pulled and distorted once the fan is switched off the picture is fine again.

I have checked all the silver shielding and that seems to have gone back OK.

Anybody any ideas?
