How do I fix a bad monitor?

Strong Bad has owned several computers and while each is superior to the last, they remain horribly dated in contrast to current technology. His first computer, the "Tandy 400", featured the classic "green-and-black" monochrome monitor and displayed little to no graphics. It eventually exploded in Strong Bad's face, at which point he "borrowed" $900 from Strong Sad to fix it, even though he could get a better one for $15 at a garage sale (according to Strong Sad). He managed to duct tape the computer back together, but after it malfunctioned and deleted an e-mail from a girl who seemed to be genuinely interested in him, the Tandy was unceremoniously dumped a few weeks later. It was bought by The King of Town, who complained that this was the last time he would buy a used computer from Bubs. The ghost of this computer at one point came back to haunt him.
