Caution: +B voltage has close relation to high voltage. To
prevent X-ray radiation, set +B voltage to the rated voltage.
Make sure that the supply voltage is within the range of the
rated value.
- Connect a digital voltmeter to the +B voltage output terminal of the TV set. Power on the TV and set the brightness and sub - brightness to minimum.
- Regulate voltage adjustment components on the power PCB to make the voltmeter read 115±1V.
DESIGN/SERVICE MODE
Caution: The user service mode adjustment can be changed
only when service personnel adjust the whole set data during servicing. As the control
data have dramatic effects on functions and performance of the TV, service
personnel should not tell user how to enter the SERVICE mode to avoid improper
data settings.- Set the volume to 0. Then press and hold the MUTE button on the remote control, and press the MENU button on the TV to enter the SERVICE mode. (In this case, the S mode cannot be stored in the EEPROM.
- To exit from the S mode, turn off the TV set. )
- After entering the S mode, Red “S” is displayed on the upper center of the screen and MENU1 is default.
- Use the POS+/ -buttons to highlight an adjustment and the VOL+/- buttons to adjust it. The adjusted data are immediately output and stored in the EEPROM.
