  1. Dear colleague, receive a warm greeting. I am very grateful that you can share your experience in repairing this oscilloscope.

    I have one like it, and I’ve been researching a hard week to try to fix it (it turns on but shows a blank screen).

    I ask you a question colleague: If my problem is the same as yours, would this prevent the 100uF / 400V capacitor from charging?

    Thank you!
