Tek 2465 Horizontal Sweep Issue

(1/5) > >>

kellymcdonald78:
I'm not sure if what I'm seeing is the hybrid chip failure or not, but for the life of me I can't seem to get a horizontal sweep (entirely possible this is user error). Everything else seems to work, I get a dot on screen, display works fine, I can adjust manually horizontally and vertically and the cursors (both T and V) work. I haven't used this scope in a decade and wanted to rule anything obvious out before I start tearing it apart. I followed the manual details to get a baseline, but no scan

Thanks

Welcome to the forum.

Check it is not set to XY mode.

I don't think so. I've got the Sec/Div switch set to 100ms locked

Can you post a clear photo of the front of the scope as this happens?  We should be able to spot any user errors that way.

Here you go. I also ran the self test and it comes back clean
