Chapter 5: Troubleshooting

Front Panel Display Trouble Isolation

101

WARNING SHOCK HAZARD!

The backlight inverter assembly, which is mounted at the front corner of the oscilloscope near the flat-

panel display, operates at 1.65 kV at turn on. DO NOT handle this assembly while it is in operation. An

LED on the inverter board illuminates to indicate the presence of high voltage.

WARNING INJURY CAN RESULT!

Once the cover is removed, the fan blades are exposed both inside and outside the chassis. Disconnect

the power cable before working around the fans. Use extreme caution in working with the oscilloscope

when the cover is removed. If the procedure allows, replace the cover over the chassis (without screwing

it back in place) before turning the oscilloscope on. If the procedure requires you to have the cover off,

be careful not to contact these fan blades with any part of your body.

For information on how to replace the display parts, see "Replacing Assemblies," beginning on page 113.
