SERVICE MENU SETTINGS
-------------------------------------------------------------------
To enter service menu, just like in the previously
launched products, we press menu button of the
remote control and enter 9, 3, 0, 1 or 8, 5, 0, 0.
As the chassis improvement and development
works go on throughout the production, service
menu items may vary according to the software
version. The following explanations are service
menu settings of the current version.
System Configuration
This menu contains general settings of the sys-
tem. Press OK button on the remote control to
access this menu.
7
TV MODE tab contains "Factory" and "Cus-
tomer" options. It is used to perform factory
controls and settings more efficiently and faster.
On the TVs delivered to the customer, this setting
is absolutely selected as "Customer". Otherwise,
it will lead to customer complaints such as "TV
automatically turns on after power failures" or
"different functions operate from the remote
control".
7
HDCP VERIFY: It must be checked whether the
HDCP key is installed during factory controls.
HDCP key stands for “High Bandwidth Content
Protection Key”. This key is used to prevent
copying of data on digital sources such as DVD
or blue-ray. With HDCP, video data is transmit-
ted from the source to the receiver as encrypted.
Therefore, to watch HDCP encrypted DVDs or
blue-ray, HDCP key should have been loaded
on TV. On the products with HDCP installed,
SUCCESS message is included.
7
DEBUG MODE is the feature, which is used to
track software modifications made on TV during
R&D stage. This setting must be "Off" on TVs
delivered to the customer.
7
PLUG PLAY (Demo Mode): A navigation key is
pressed after having completed all settings and
checks in the factory. Later, "Please wait" mes-
sage appears; and when you see the message
"DONE", the device should be unplugged and
plugged again. With this process, television will
be set to its initial values before delivery. It will
be proper to set Plug&Play tab after service.
After pressing right key on the tab, the flash will
be installed with factory defaults. TV can be
shipped to the customer after this setting. Please
note that any warning is not displayed or you
do not have to exit the menu while Plug&Play is
getting activated. You should be careful not to
take the device into Plug&Play mode by mistake.
7
HOTEL tab should be set to "On" with the
products for which the Basic Hotel TV feature
is desired; and it should be set to "Off" in other
products. When the hotel model is "On", certain
features designed for the hotel use are activat-
ed; the user cannot change the channels set by
the service, for example, or the volume cannot
be increased more than a certain level.
7
CI KEY VERIFY indicates whether the CI Key
was installed. This menu cannot be changed.
This option should appear as "Pass" in the prod-
ucts with CI Plus feature. CI Key is the keyword
on the card which is inserted to decrypt the
broadcasting. This menu is a control indicator
and changes automatically. This keyword is
installed during TV production and it becomes a
kind of ID for your TV when watching encrypted
channels. GF-chassis products support CI+
feature. Launched in 2008, it is a new encryp-
tion standard developed with the collaboration
of consumer electronics and scrambled digital
broadcasting companies. It was possible to
copy the programs after decoding process;
however, now they cannot be copied because
IC that comes with CI Plus has a key. In this
system, broadcasting is initially decoded on CI
card. The broadcasting transmitted to the main
IC from the CI card is also encrypted and it is
decoded with CI Key, which is a factory setting
and different for each TV. Thus, there will be no
free encrypted broadcasting on the bare line
and encrypted broadcasting cannot be copied.
