The following adjustment procedures are accessed thru a service menu. To access the service menu, turn the receiver on, press the menu button and hold it down
while pressing the power button. While holding down the menu button, release the power button and press the volume + button. The screen will display a one
line menu, on the left the parameter P0, and on the right the value of that parameter V0. Release buttons. Adjustments are made by selecting the proper param-
eter and changing the value of that parameter. To change the parameter number use channel up and down buttons. To adjust the current value of that parameter
use volume + and - buttons. To access and change any of the adjustments, the proper parameter pass number must be entered. This information is listed at the
beginning of the alignment. When these parameters are modified, the T-Chip and the corresponding EEPROM are updated. All service adjustments are bus
controlled, except focus and screen.
NOTE: In order to adjust the RF AGC, audio or video levels, tuner, PIP, or stereo circuits, the ChipperCheck hardware and software must be used. This can be
purchased from Thomson Electronics. Before making any changes to any of the values, record the On Set values.
