5.4.6 Content and Usage of the One-Zip Software File
Below you find a content explanation of the One-Zip file, and
instructions on how and when to use it. Only files that are
relevant for Service are mentioned here.
• EDID_clustername.zip: Contains the EDID content of the
different EDID NVMs.
• FUS_clustername_version.zip: Contains the file
downloaded which is needed to upgrade the TV main
software and the software download application.
• NVM_clustername_version.zip: Default NVM content.
5.4.7 How to Copy NVM Data to/from USB
When copying data to and from a USB memory stick, the folder
"repair" is used. When inserting an empty USB memory stick,
and downloading data to the stick, the TV will create this folder.
When sending data from a USB memory stick to a TV, the
intended data must be available in the "repair" folder.
Note that when copying EDID data to the TV, all necessary
EDID files must be in this folder.
Service mode overview for your reference.
Table 5-3 Service mode overview
Service Modes Description
SAM Service alignment mode
Factory Mode Used for extended alignments
CSM 3-page compact CSM pages. There will be CSM dump to
USB-stick upon entering CSM-mode
USB SW upgradeable SW-upgrading of flash memories MT5596LGIJ can be
done via USB. The main SW can be upgraded via the ZIP
file downloaded.
NVM-Editor in SAM NVM-editor will function as in the past: Address and Value
field is a decimal value via digit entry
Service Data New Service data in SAM for CTN, Prod. no., 12NC
programming with virtual keyboard
USB copy/paste in Channel list, NVM data, Readable info, EDID
SAM
UART logging There will be printout available in UART. No specifications
of the printout, per MTK provision/definition.
Blind SAM RC sequence "062598" + "Menu" +
"Panel code"
Clear Buffer RC sequence "062599" + "OK" or via SAM
5.5 Error Codes
5.5.1 Introduction
Error codes are required to indicate failures in the TV set. In
principle a unique error code is available for every:
• Activated (SW) protection.
2
• Failing I C device.
2
• General I C error.
The last five errors, stored in the NVM, are shown in the
Service menu's. This is called the error buffer.
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.
An error will be added to the buffer if this error differs from any
error in the buffer. The last found error is displayed on the left.
An error with a designated error code never leads to a
deadlock situation. It must always be diagnosable (e.g. error
buffer via OSD or blinking LED).
In case a failure identified by an error code automatically
results in other error codes (cause and effect), only the error
code of the MAIN failure is displayed.
5.5.2 How to Read the Error Buffer
You can read the error buffer in three ways:
• On screen via the SAM/CSM (if you have a picture).
Service Modes, Error Codes, and Fault Finding
Example:
– ERROR: 000 000 000 000 000: No errors detected
– ERROR: 013 000 000 000 000: Error code 13 is the
last and only detected error
– ERROR: 034 013 000 000 000: Error code 13 was
detected first and error code 34 is the last detected
(newest) error
• Via the blinking LED procedure (when you have no
picture). See paragraph
5.5.3 Error codes
In this chassis only "layer 2" error codes are available and point
to problems on the SSB. They are triggered by LED blinking
when CSM is activated. Only the following layer 2 errors are
defined:
