Alternative method (1):
1. Go to SAM.
2. Select NVM Editor.
3. Select ADR (address) to 1 (dec).
4. Change the VAL (value) to 170 (dec).
5. Store the value.
6. Do a hard reset to make sure new default values took
place.
Alternative method (2):
It is also possible to upload the default values to the NVM with
ComPair in case the SW is changed, the NVM is replaced with
a new (empty) one, or when the NVM content is corrupted.
After replacing an EEPROM (or with a defective/no EEPROM),
default settings should be used to enable the set to start-up and
allow the Service Default Mode and Service Alignment Mode to
be accessed.
5.7.3 Start-up/Shut-down Flowcharts
Important note for DVB sets:
• When you put a DVB set into Stand-by mode with an RC,
the set will go to "Semi Stand-by" mode for 5 minutes. This,
to facilitate "Off the Air download" (OAD). If there is no
activity within these 5 minutes, the set will switch to Stand-
by mode. In "Semi Stand-by" mode, the LCD backlight and
Audio Amplifier are turned "off" but other circuits still work
as normal. The customer might think the set is in Stand-by.
However, in real Stand-by mode, only the uP and the NVM
are alive and all other circuits are switched "off".
• If you press the mains switch at the local key board in a
DVB set, the set will switch to Stand-by mode.
On the next pages you will find start-up and shut-down
flowcharts, which might be helpful during fault finding.
Please note that some events are only related to PDP sets,
and therefore not applicable to this LCD chassis.
