I am about to purchase a old 8590 SA, which is quite cheap because of this issue. This unit can display spectrum of calibration signal and all the other characters on screen, but the screen is full of snow and there are few vertical lines. It looks like the CRT draws grids the wrong way. Is it the setting problem or there are something wrong inside.
