CUSTOMER SERVICE MODE (CSM)
1. The Customer Service Mode (CSM) is used to retrieve data on the TV operation settings and stored error
codes.
2. To enter the Customer Service Mode, press and hold the Mute button on the remote control and any key
on the local keyboard (except "Power") for more than 4 seconds. When the set is in Customer Service
Mode, the text "CSM" is displayed in the top right corner of the screen.
3. To use this system, the customer is instructed to enter CSM and read off the display that appears. This
information is useful to gain insights into failures before traveling to the customer's home.
4. This information can also be used to avoid nuisance trips to the home when the problem is an operational
error (example: Closed Caption is on or set is in Hospitality Mode).
5. When entering CSM, all disruptive functions are turned off, and service unfriendly modes are ignored.
While CSM is active, no changes can be made in settings or functions. When CSM is exited, the TV
returns to all prior operational settings.
6. To exit CSM, press any key (on the remote control or local keyboard) except "Channel Up" or "Channel
Down."
To exit CSM and return the set to normal operation mode, press any key on the local keyboard or the
remote control except Channel Up, Channel Down, or Power.
To exit CSM and turn the set off, press the Power button on either the TV set or the remote control.
7. A sample CSM display is shown below.
