Also it doesn't work. The low voltage power supplies looks OK, but nothing on the display, except the illumination. Even doesn't respond to the knobs, no startup beep.
Anyway. I wanted to quickly check my theory, that my original scope has probably a single failure on the processor board and no other problems.
So I gave a try. Swapped the processor boards.
The unit is working. At least it give sharp image, respond to the knobs/buttons. Didn't had time to check it further, but this is promising.
Here come the question:
Is it worth?
Worth to try to repair the other unit? Find missing knobs, print a new frame, glue the broken things, try to repair not just the processor board, but the other things could I face during the attempt.
I have some internal pressure to challenge myself, but ...
I don't know. We will see.
