ervice Mode (C

Purpose
When a customer is having problems with his TV-set, he can
call his dealer or the Customer Helpdesk. The service
technician can then ask the customer to activate the CSM, in
order to identify the status of the set. Now, the service
technician can judge the severity of the complaint. In many
cases, he can advise the customer how to solve the problem,
or he can decide if it is necessary to visit the customer
The CSM is a read only mode; therefore, modifications in this
mode are not possible
When CSM is activated:
•
A test pattern will be displayed during 3 s. This test pattern
is generated by the MT822x video processor. So if this test
pattern is shown, it could be determined that the back end
video chain (MT822x, LVDS, and display) of the SSB is
working.
•
The LAYER 1 error is displayed via the blinking front LED.
Only the latest error is displayed. See also section 5.4 Error
Codes.
How to Activate CSM
Key in the code “123654” via the standard RC transmitter.
Note
: Activation of the CSM is only possible if there is no (user)
menu on the screen!
How to Navigate
By means of the “Arrow up/down” button on the RC-transmitter,
one can navigate through the menus.

this way, it is not necessary for the customer to look at the

initialized after corruption, this model type has to be re-
written to NVM. ComPair will foresee in a possibility to do
this.
•
