no program position is stored, it can automatically enter into auto-search mode
after start-up.
6-3. EEPROM check function
When EEPROM is damaged, TV set can not work normally, because the bus
adjusting data and the result of setting options are stored in EEPROM. Therefore
CPU will automatically check EEPROM upon cold start-up. If the bus connected
with EEPROM is found making errors or the EEPROM is making errors initial
data will be called after start-up and forced blue background will turn up, with
flashing OSD displaying "EEPROM ERROR PLEASE CHECK" in big letters. In
this case, no operation can be done except turning off to check. If EEPROM is
partially damaged
6-4. User's remote control unit enabling "FACTORY" button function

troubles to maintenance after TV sets exit the factory. Therefore a function
equivalent to "PROD" function is specially designed in the software. Its operation
is as follows
First press "REVIEW" button
set and meanwhile press the "REVIEW" button again. The function of "PROD"
button is enabled then. Repeat the above steps can operate again.
6-5. EEPROM initialization function
During cold start-up, CPU will check automatically if new EEPROM is used (e.g.,
EEPROM is replaced in maintenance). If a new EEPROM is found CPU will
automatically read in initial data and store the data in the new EEPROM to ensure
normal operation.
6-6. Setting of factory flag and power logo
The factory flag consists of two lines, with 12 characters for each, which can be
used to set different content, on/off, style and size of characters, color, vertical
position and horizontal position. If factory flag is set and at least one line is set to
"ON", POWER LOGO will turn up after start-up if "POWER ON LOGO" is set to
"1". If at least one line is set to "ON", then factory flag OSD will appear when no
signal is received.
