Page 2 of 22 E5071C-31A

For E5071C Opt 240 to 485 – Up to 8.5 GHz range

Situation:

For E5071C (serial prefix of MY461, MY462 and MY463), due to the part discontinuance by LCD
display manufacturer, the E5070-60112 LCD-Touch Panel Assembly (with LCD Display with CCFL
backlight) is no longer supplied.

The replacing part would be an LCD Touch Panel Display Assembly with LED backlight. In ensuring
hardware compatibilities, there would be a list of associated parts required to be replaced whenever the
LCD T/P assembly (LCD Display with CCFL backlight) is defective.

Solution/Action (For E5071C Opt 240 to 485 – Up to 8.5 GHz range)

LCD Removal
Refer to E5071C Service Guide (Chapter 6- Replacement Procedure  LCD Replacement) for the
step-by-step procedure.

Front Panel Keyboard Removal
Refer to E5071C Service Guide (Chapter 6- Replacement Procedure  Front Panel Keyboard
Replacement) for the detailed procedure.

Probe Power and Power Switch Board Removal
Refer to E5071C Service Guide (Chapter 6  Probe Power and Power Switch Board Replacement
(A56) for detailed instructions.

Note: Kindly take note to keep the original parts as some of the assemblies are reusable and
replacement is not necessary.

Page 3 of 22 E5071C-31A

For defective LCD T/P Assembly E5070-60112

In summary, whenever LCD T/P E5070-60112 is identified defective, replace the following parts
altogether as they are mutually dependent:

1. LCD T/P assembly (with LED backlight display),

2. Inverter

3. Front Panel (label, panel sub, shield)

4. Cable assemblies,

5. Screws etc.

In this case, apart from replacing the LCD T/P assembly with the replacement part, the inverter is
required to be replaced in ensuring the compatibility with the new LCD T/P assembly (with LED
backlight). Front panel needs to be replaced as the dimension and the new LCD T/P assembly screw
size and location differs on the new LCD T/P display assembly (with LED backlight). Refer to table 1­1 for details.

For other failures (other than LCD T/P assembly E5070-60112)

If the defective part does not include LCD Touch Panel Assembly, proceed to replace the individual
defective parts directly as usual. For instances, if the inverter 0950-4420 is found to be defective,
replace the inverter alone will be sufficient. Similar applies to Touch Panel controller. Those parts are
continuously supported and supplied until further notice. Refer to service guide for detailed
instructions.
