Power Supply Trouble Isolation

WARNING SHOCK HAZARD!

Only trained service personnel who are aware of the hazards involved should perform the maintenance

Read the safety summary at the back of this book before proceeding. Failure to observe safety

precautions may result in electric shock

For information on how to replace assemblies, see "Replacing Assemblies," beginning on page 113.

These trouble isolation instructions help isolate the problem to the assembly level when the power system

is not operating. Because of advanced power system protection features, the problem may not be with

the supply itself and, therefore, you will need to use the LEDs located in the upper right hand corner of

the acquisition board to determine the fault. These LEDs can be seen by looking through the rear fan

slots in the upper right hand corner as viewed from the rear of the oscilloscope. After a shutdown occurs,

keep the power cord plugged in so the LEDs remain illuminated. Once you have noted the LED pattern,

you can unplug the instrument.

If the oscilloscope still will not power on after you have followed the required steps below, refer to the

Motherboard Verification section in this chapter for additional diagnosis suggestions.
