This seems to work, at least the values that i could read on some
test-points were correct, unfortunately i do not have a service manual
or anything that would tell me what the correct voltages of other
test-points are (i could only test the ones where their supposed voltage
values is written on the board).

Sigh, i am absolutely ignorant about oscilloscopes and without a manual
to tell me exactly what to do i am lost

I wish i knew where those pins are, i do not really feel like to
short-circuit random pins. Sigh... anyone knows where i could find the
service manual of this oscilloscope without having to buy a copy?

Thank you for your answers,
