SOP of Firmware Upgrade

ATV Firmware Upgrade - Com port

Using USB to D-Sub 15 cable

1. COM Port and baud rate (9600 bps).

2. Select Read to load the file to be programmed into TV.

3. Push the button of Connect to connect TV and indentify the type of flash memory in TV.

4. Push the Button of Run to start program firmware.

• Working method ◦ Unlike the USB upgrade (to be mentioned later) the whole code in flash memory

will be upgraded completely.

◦ This upgrade method can be done even the flash memory is blank.

ATV Firmware Upgrade - USB

Copy an available file (to be mentioned later) into USB memory disk.

2. Insert USB flash disk with an available file into TV USB port.

3. Reboot (AC Off/On) TV to update firmware automatically, during upgrading f/w a progress slider bar will be shown on display.

4. Once f/w upgrade is finished, a message of "Update Finished" will be shown on display.

5. Remove USB flash disk then turn AC Off/On to reboot TV, new f/w will be active.

Available file name

• In order to not upgrade firmware with incorrect code which is for other model, only the bin filename consistent with the current upgraded model is considered available, i.e. the model name located in first 8 characters of filename will be checked.

• The first found file with available file name will be applied for upgrade, so it is recommended to keep only one available file for one model is flash disk.

• For example 19AV703X_XXX_REV01.BIN. the model name 19AV703X (in blue) should match to current upgraded model and total length of file name should be 23 characters, characters in red is not cared.

Available file name, Continued

• Table 1. the file name of firmware for 703X series.

Model Name File Name of BIN Code

19AV703X 19AV703X_XXX_REVXX.BIN

22AV703X 22AV703X_XXX_REVXX.BIN

26AV703X 26AV703X_XXX_REVXX.BIN

32AV703X 32AV703X_XXX_REVXX.BIN

32LV703X 32LV703X_XXX_REVXX.BIN

37LV703X 37LV703X_XXX_REVXX.BIN

40LV703X 40LV703X_XXX_REVXX.BIN

Table 1. Firmware naming

• Internal Working Method

◦

There are two part of codes in flash memory one is boot code the other one is

application code.

◦ At power up stage Boot code is first running up, it will check if there is USB

flash memory found.

◦ If USB flash memory is not found then the program will run to application code

which is the one designed for whole system control such as OSD, remote control, display control etc.

• Internal Working Method, Continued

◦ If USB flash memory is found, boot code will check if any available file name

memory disk, if it is then the whole file with 2048K bytes (if it's a firmware) will be copied to DDR memory first.

◦ After copy is finished, program jump to DDR and copy the part of new

application into flash memory on board.

◦ Once upgrade is done, program will keep waiting for reboot.

• Internal Working Method, Continued

◦ As boot code will not check any of checksum, care should be taken to avoid any

of invalid file with file name as Table 1. in USB flash memory while running firmware upgrade process.

◦ As boot code and application code are running independently, after program runs

to application code the boot code is not able to be found by application code, so it is not possible to implement USB upgrade directly from application code.

◦ This upgrade method can be done only when boot code is exist in flash memory.

Handling the LCD Module

Safety Precaution

In the event that the screen is damaged or the liquid crystal (fluid) leaks, do not breathe in or drink this fluid. Also, never touch this fluid. Such actions could cause toxicity or skin irritation. If this fluid should enter the mouth, rinse the mouth thoroughly with water. If the fluid should contact the skin or clothing, wipe off with alcohol, etc., and rinse thoroughly with water. If the fluid should enter the eyes, immediately rinse the eyes thoroughly with running water.

Precautions for Handling the LCD Module

CAUTION: The metal edges of the LCD module are sharp, handle it with care.

The LCD module can easily be damaged during disassembly or reassembly; therefore, always observe the following precautions when handling the module.

1. When attaching the LCD module to the LCD cover, position it appropriately and fasten at the position where the display can be viewed most conveniently.

2. Carefully align the holes at all four corners of the LCD module with the corresponding holes in the LCD cover and fasten with screws. Do not strongly push on the module because any impact can adversely affect the performance. Also use caution when handling the polarized screen because it can easily be damaged.

3. If the panel surface becomes soiled, wipe with cotton or a soft cloth. If this does not remove the soiling, breathe on the surface and then wipe again. If the panel surface is extremely solied, use a CRT cleaner as a cleaner. Wipe off the panel surface by drop the cleaner on the cloth. Do not drop the cleaner on the panel.

Pay attention not to scratch the panel surface.

4. Leaving water or other fluids on the panel screen for an extended period of time can

result in discoloration or stripes. Immediately remove any type of fluid from the screen.

5. Glass is used in the panel, so do not drop or strike with hard objects. Such actions can damage the panel.

6. CMOS-LSI circuitry is used in the LCD module, so avoid damage due to static electricity. When handling the module, use a wrist ground or anchor ground.

7. Do not expose the LCD module to direct sunlight or strong ultraviolet rays for an extended period of time.

8. Do not store the LCD module below the temperature conditions described in the

specifications. Failure to do so could result in freezing of the liquid crystal due to cold air or loss of resilience or other damage.

9. Do not disassemble the LCD module. Such actions could result in improper operation.

10. When transporting the LCD module, do not use packing containing epoxy resin (amine) or silicon resin (alcohol or oxim). The gas generated by these materials can cause loss of polarity.
