I have a Mac Plus that was having some display issues so I replaced the analog sweep board. The issues that I were having are gone and the display seem to work perfectly except that the height is way out of whack. It's centered just fine vertically and it's the correct width, but its only about an inch tall. Everything is there, it's just compressed. I opened up the case and even with the height adjustment cranked all the way in the positive direction it's way too small. Is this a common problem and is it easily fixed?
