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
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 parameter 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 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.

Press menu button for collapsed raster service line. Disconnect the
antenna. Preset the red, green, and blue drive values to 32. Adjust
screen control for a service line that is just visible. Adjust red,
green, and blue drives to obtain a white raster. Check the low light
to high light gray scale tracking. Repeat the procedure, if neces-
sary, to obtain the best performance.
