To access the Factory Menu, press and hold the MENU key until the User Menu display disappears, then press 9876, and then ENTER.
To access the Factory Menu, press and hold the MENU key until the User Menu display disappears, then press 9876, and then ENTER.
The black bar near the top of the screen indicates the part
number of the software in the TV set. To the lower right is a number indicating
that the module has been tested. The date on the black bar near the bottom left
of the screen indicates the date the module went through the factory.
When the Factory Menu appears, it displays the fourth Factory
Menu item: VERT POS. Use the SELECT UP/DOWN keys to toggle through all of the
adjustments. Uses ADJUST to make a change to the selected item.
00 FACT MENU: Use SELECT UP
and DOWN Keys to select item 00, the Factory Mode. The Factory uses this item
when the module is being tested. It has two positions: 0 and 1. In the field,
this item should always be left off (Zero is off).
When this item is off, only the first seven items in the Factory Menu can be accessed. They appear one at a time near the middle left of the screen. When this item is set to 1, 59 menu items are available. In the Factory Menu, only the selected menu item is displayed, near the top of the screen, as shown in the figure.

Lamp error detection
Function
This LCD color TV set incorporates a lamp error detection feature that automatically turns off the power for safety under abnormal lamp or lamp circuit conditions. If by any chance anything is wrong with the lamp or lamp circuit or if the lamp error detection feature is activated for some reason, the following will result.
* The power is interrupted in about 6 seconds after it is turned on. (The power LED on the front of the TV set turns red from green and keeps blinking in red: ON for 250 ms and OFF for 1 sec.).
* If the above phenomenon 1) occurs 5 times consecutively, it becomes impossible to turn on the power. (The power LED remained red).

Measures
Checking with lamp error detection OFF
Enter the adjustment process mode, referring to 1. Entering and exiting the adjustment process mode. If there is a problem with the lamp or lamp circuit, the lamp will go out. (The power LED is green.) Then, you can check the operation to see if the lamp and lamp circuit are in trouble.
Resetting the lamp error count
After the lamp and lamp circuit are found out of trouble, reset the lamp error count. If a lamp error is detected five consecutive times, the power cannot be turned on. Using the cursor (UP/DOWN) key, move to the cursor to [LAMP ERROR RESET], Line 8 on adjustment process mode service page 2/33. With the cursor (LEFT/RIGHT) keys, select the [LAMP ERROR RESET] value. Finally press the cursor (ENTER) keys to reset the value to “0”.

Operation procedure
The initial input position is the digit at the left end.
For the numeric keys to of R/C, key input is accepted. Input of the other keys is prohibited.
Change “-” to “*” by inputting the numeric key at the input position, and shift the input position rightward one digit.
When three digits are completely input, the Pass Word is judged.
c Check the Pass Word by inputting three digits.
If the Pass Word is[0] [2] [7] , it shifts to the PUBLIC Mode setting screen.
In another case, the screen is erased, and it operates in the ordinary mode.

Exiting the Public Mode screen
There are two following ways to exit the Public Mode setting screen.
1 Turn off the power.
2 Select “Execution” in the PUBLIC_Mode to execute it. Activate the restart under the set content. Here, the START input SOURCE setting is excluded since this item is referred to only when the power is turned on.
3. Set value of the Public Mode
Each set value in the PUBLIC Mode is initialized when the factory setting is applied. (The setting of the PUBLIC MODE Flag in the process adjustment mode screen is not changed.)

Each set value in the PUBLIC Mode is initialized when the factory setting is applied. (The setting of the PUBLIC MODE Flag in the process adjustment mode screen is not changed.)
Basic operation in the Public Mode
> Volume +/- or Cursor L/R:
Change or execution of the set value.
> Channel Up/Dn or Cursor Up /Dn: Movement to the selected item.
> Decision (ENTER): Execution
(Used by the items “Execution” and “RESET”.
> PUBLIC Mode R/C: Ordinary
operation mode: It enters the PUBLIC Mode.
PUBLIC MODE Flag is set to “ON”.
> PUBLIC Mode: It exits the PUBLIC Mode. PUBLIC MODE Flag does not
change. Any set item in PUBLIC Mode is
not initialized.
Operation after “RESET”
Select “RESET” in the PUBLIC Mode, and it operates as follows when it is executed (refer to the basic operation).
The set contents in the PUBLIC mode are initialized.
It does not exit the PUBLIC mode.

Upgrading the software
> Turn off the AC power (Unplug the AC power cord).
> Insert the upgrading USB flash memory for upgrade into the service slot.
> While holding down the power button, plug in the AC power cord of the main unit to turn on the power.
> Upgrade begins automatically. After the set starts, the upgrade screen appears.
> Turn off the AC power (Unplug the AC power cord).
> Insert the upgrading USB flash memory for upgrade into the service slot.
> While holding down the power button, plug in the AC power cord of the main unit to turn on the power.
> Upgrade begins automatically. After the set starts, the upgrade screen appears.
If any of the procedures fails, the following upgrade failure
screen shows up. For the failing procedure, the “NG” marking turns red. NOTE: In such case, try to upgrade the
software again. If it still fails, the hardware may be in trouble.
> When all the procedures are complete, the following upgrade
success screen shows up. The new software version can be confirmed on screen. The version number appears when each item has been successfully upgraded.
Finally the main version number appears on screen.
> Turn off the AC power (Unplug the AC power cord). Take out the
upgrading USB flash memory.
Now the software has been upgraded.
NOTE: Then get the set started and call the process adjustment screen 1/32 to check the main software version.
CAUTION
1 Do not take out and put in the USB flash memory during formatting.
2 It takes about one minute to the rewriting completion.
Confirm the upgrade status on the screen becomes 100%.
