Hi! I have acquired an older LeCroy oscilloscope from someone. It used to work, but now when I plug it in, the screen is orange (normally letters and lines and things are orange, but now the whole length of the screen is). It doesn't take up the entire screen, but I cannot see any menus where they should have been either. Does anyone have any thoughts on this? It still prints out waveforms on paper, just the display is being a jerk. I haven't been able to find much online. Thanks in advance!
