OSCILLOSCPE TESLA BM566A PROBLEM
« on: April 16, 2017, 10:44:20 am »
HI
I have an old Tesla BM566A oscilloscope.
it works some years without any problem. yesterday I tried to see a signal but it shows nothing! even zero line.
I'm sure that display is working because when I push "beam finder" button it works correctly.
I opened the case cover and in first I found no problem like capacitors crack.
anyone can guide me how to fix the problem?

thanks for your replay.
schematics is not useful at this time because I have no idea which unit cause the problem.
