Hotel Mode, Service Modes
5.1.1
Hotel Mode
Before the service modes can be activated, the set needs to
beswitched into normal consumer mode (MTV-Mode) first. Use
an iTV setup remote control (type: RC2753/01, 12nc: 3139 228
88782) to key in the code ‘024995’ directly followed by the
MENU button. The text messages “TV Is Now In MTV Mode”
and “Please Do A Cold Start !” appears on the screen.
Disconnect the set for a few seconds from the mains supply,
reconnect the set to the mains supply again. The set is now in
the normal consumer mode (MTV-Mode).
After repair, place the set into hotel mode (iTV-Mode) again.
Key-in the same code on the remote control as described
above. The text message “TV Is Now In ITV Mode” appears.
A cold start must be performed as described above. The set is
now in the hotel mode (iTV-Mode) again.
5.1.2
Service Modes
Only when the set is in normal consumer mode (MTV Mode),
all service modes can be accessed. Refer to the main chassis
manual for further explanation of the service modes.
5.2
Error Codes
The error code buffer contains all errors detected since the last
time the buffer was erased. The buffer is written from left to
right. When an error occurs that is not yet in the error code
buffer, it is displayed at the left side and all other errors shift one
position to the right.
