Folks, I've just received this wonderful piece of history. It seems to power up and boot, however, the LCD doesn't work well. Playing with both the LCD dials, I was able to get sort of a picture for a while, but with number of vertical bars, and the picture more or less disappeared.
I am going to open it sooner or later and see if there's something obviously wrong, but perhaps you have more experience with this kind of problems?

Thanks!
