Can you help me fix it. The screen now acts like Windows acts if you put in the wrong resolution setting...lines flashing up and down in black and white with no content visible. Tried holding on down for 20 secs. Didn't work. Duh....I've only been fussing with computers since my first Vic 12 k. So I'm not out of computers my basement is full of them.
