| Hameg HM407 oscilloscope display problem |
| (1/1) |
| gboutique:
My hameg HM407 analog-digital oscilloscope is having a display problem on the screen. All display is shifted 3mm down. I have searched the service diagrams, and can't find the trimmer that will allow me to correct this problem. Can someone help me or guide me? |
| Andy Watson:
It could be a trick of the camera or lighting, but is that the top of the tube that I can see? Looks like the tube has physically moved down. |
| gboutique:
no, no trick... the tube is fine, fixed and aligned. the problem is the whole frame display is now shown deviated a few millimeters downwards. |
