Chapter 4: Troubleshooting

To check the LEDs

If you see a failure with the on/off switch backlight LED, replace the ON/OFF board. If the LED

will still not illuminate, replace the motherboard and see if this fixes the problem. If the LED

still does not work, the last option is to check the on/off cable connecting the ON/OFF board

to the motherboard.

If any of the other LEDs are not working on the front panel, the first step is to trouble shoot the

acquisition assemblies to make sure they are working. If they are working then replace the

keyboard assembly and see if the LEDs will illuminate. If the LEDs will not illuminate, the last

step is to reload the oscilloscope software.

When reassembling the oscilloscope all boards that were replaced, but turned out not to be

causing the problem should be reinstalled in the oscilloscope.
