Preparation
WARNING. Before doing this or any other procedure in this manual, read the
Safety Summary found at the beginning of this manual. Also, to prevent possible
injury to service personnel or damage to the oscilloscope components, read
Installation in Section 2, and Preventing ESD in this section.
This subsection contains the following items:
H The preparatory information you need to properly do the procedures that
follow.
H List of tools required to remove and disassemble all modules.
H Procedures for removal and reinstallation of the electrical and mechanical
modules.
H A disassembly procedure for removal of all the major modules from the
oscilloscope at one time and for reassembly of those modules into the
oscilloscope.
WARNING. Before doing any procedure in this subsection, disconnect the power
cord from the line voltage source. Failure to do so could cause serious injury or
death.
NOTE.ReadEquipment Required for a list of the tools needed to remove and
install modules in this oscilloscope. See Table 1, page 5.
Read the cleaning procedure before disassembling the oscilloscope for cleaning.
Equipment Required. Most modules in the TDS5000 Digital Oscilloscope can be
removed with a screwdriver handle mounted with a size T-15, TorxR screwdriver tip. Use this tool whenever a procedure step instructs you to remove or install
a screw unless a different size screwdriver is specified in that step. All equipment required to remove and reinstall each module is listed in the first step of its
procedure.

Trim Removal
1. Orient the oscilloscope: Set the oscilloscope on the work surface with its
rear facing you.
2. Remove the line cord: Pull the line cord away from the AC power connector.
3. Remove the front panel trim:
a. To prevent the power button from falling out of the front panel trim,
place a piece of tape over the button.
b. Remove the three T-15 Torxdrive screws that secure the front panel trim
to the oscilloscope. See Figure 1, on page 8.
c. Grasp the trim ring by its top edge and pull toward you to detach the
three plastic snaps. (Alternatively, you can use a flat-bladed solder aid or
other small prying tool to help you detach the snaps.)
d. Grasp the trim ring by its side edges and slide it back and forth to release
the snap in the middle of the trim ring. The snap is at the bottom “T” of
the front panel above the channel 1 and 2 BNCs.
