Our oscillograph InfiniiVision 4000X MSO-X 4154A was not used very long time .
Now the oscillograph is not starting: after pressing power-on key all LEDs on a control panel blink twice.
After that only one LED (near "Ref" button) is on.
The display keep black, fan work, oscillograph does not react to pressing any button.
How can I resolve this issue?
Whether it is possible to make something youself without addressing to Repair Service? The warranty already expired.
