The J Series Wiki
Here will be the information about Tizen OS and J series soon.
This is a misc. collection of currently known information. It will be organized better over time.
Be VERY careful once in the service menu. Do not try to navigate using LEFT and RIGHT because that changes values. Only navigate through menu items with UP and DOWN.

With TV powered off: [MUTE]    on American models and [INFO] [MENU] [MUTE] [POWER] on European models.

RS-232 Jack setting:
UART = no input/output
Debug = system logging output (MUCH more verbose when "Serial Log On/Off" set to ON, which requires a power cycle to take effect)
Logic = no input/output
FANET = no input/output
OTN Support Disable (Firmware Upgrades)
OTN support cannot be disabled in the service menu. It must be disabled by blocking access to the upgrade servers at the network level.
