Oscilloscope Hitachi V212 Repair
« on: October 23, 2024, 05:35:17 pm »
Hi, i was using the oscilloscope without problems until a whining noise started and after a few seconds the screen stopped showing any signal. I opened the oscilloscope and saw that the diode D1012 was physically cut but after replacing it with a 2CL70 diode it didn't fix the issue.

Any tips about what could be the issue and what i can test?

See the attached service manual page 69

Hi

Have you checked F1001 a 0.25A fuse?
