My employer came to me with a little project. The office projector stopped working properly after someone touched the pins of the VGA video cable, and presumably released ESD energy into the projector. The picture’s colours were all tinted and washed out!
Note that the bottom monitor is displaying the same colour pattern
as the projector. Grey is completely missing!
He asked me if I’d like to take a look at it. My answer, as would be expected, was “of course!”
