Bad LCD shows inverted colours

I was recently asked by a gentleman in Llanberis to take a look at his laptop as the screen was displaying strange colours. Upon starting the machine it was found to have inverted colours – what should have been red came out as green and the whites came out as a pale blue. There was also some splotches of pink dotted around the screen.

If you have this problem, the first thing to check is that the graphics chip isn’t at fault (graphics problems are rarely fixable and often would cost more than a new laptop). You will need a computer monitor to plug into the vga socket(or dvi socket, both shown below).

With the monitor plugged in, start up your laptop. The laptop should use the monitor to display the image but if not you may need to press the function key (marked Fn, usually in blue) and either F8 or F4.

If the picture on the external monitor is showing the same strange colour scheme then unfortunately the graphics chip has gone bad and you should invest in a new laptop. If the picture is fine then the problem is with the lcd screen. Changing screens on laptops is difficult and time consuming but can be done as long as you have the right tools and a lot of patience.
