I was using my TekTronics 465B to repair another generic oscilloscope then accidentally I touched a contact point sticking out upwards from the generic scope’s board. I must have touched a very high voltage point because I did see a very small spark at the moment of contact, within a couple of minutes the waveform of my TekTronix slowly began to fade away. Now the screen is half illuminated, (diffusely illuminated) from the right side to the center and to the left side is a bit darker (sort of like a half moon effect). Only the intensity control seems to have any effect at all on the display, but it doesn’t do much other than make the screen just a tad brighter.
Does anyone have any idea at all what I must have ruined on this old trusted friend. I am so pissed I have hand this scope since 1989 and it had been working great since then till I messed it up.
Please help. Thank you very much for your help.
