CUSTOMER SERVICE MENU
The Customer Service menu is provided in order to assist fault diagnosis when the customer reports a problem. The menu
can be invoked by the customer on request from the service technician or dealer during a telephone conversation. The
customer is then able to provide information regarding the current status of the set. The information gained can then help to
increase the number of problems that are solved on the first call out by the service engineer and also reduce the amount of
“No problem found” cases. The Customer Service Menu will be read only, preventing the customer from modifying the state
of the TV at this time.
