HI, anyone out there who has repaired these scopes or has a good idea of the problem area I should be looking to solve the problem that this scope now has?
I know the scope is old, but the last time I used it three years ago it was in perfect spec. I have now a need to use the scope and I find it has the following problem:
All functions of the scope work OK except for the scan.
The scan operates as normal except that it scans only to half way across the tube. The width and expander controls are OK but will not bring the trace to full tube face coverage.
I have a manual for the scope on the way to me so that I will not be completely in the dark, but it would be most helpful to have a good idea of where the problem lies! My guess at the moment is that the X scan drive voltage has gone down or low!
So if you can help please do, many thanks in advance, Brian
