3. PICTURE ADJUSTMENT

Four screens for Normal/Full, Theater wide 1, Theater Wide 2, Theater Wide 3 are provided for the adjustments. When making the adjustments, receive the U/VHF or CABLE broadcasting signal or the built-in pattern signal of the mi- croprocessor to make a synchronization with the frequency of the adjusting screen with the unit..

This adjustment program is prepared as the microprocessor function of the set and it is possible to adjust by the remote controller attached.

3-1. Outline of the Modification Process of the Storing Adjustment Data

Set the convergence adjustment screen.

The adjusted data is stored in the memory inside Q713 E2CPROM which is a non-volatile memory.

The RAM data inside Q701 is lost when the power turns off. So the initial operation status is set by the software com- mand from the microprocessor QA01 every time when the unit turns on.

The data adjusted manually through the screen by displaying the adjusting screen on the display is once written on RAM inside Q701. Adjust each adjusting point and store the modi- fied total data on RAM as correct one into Q713 E2PROM.

The adjustment is carried out for each screen mode, and its order is as follows; Normal/Full ® Theater Wide 1 ® the- ater Wide 2 ® Theater Wide 3. (When the adjustment value is saved after adjusting Normal/Full, the microprocessor cal- culates the adjustment values for Theater Wide 1, 2 and 3 based on the adjustment value of Normal/Full mode and sets the values for Theater Wide 1, 2 and 3 to the closed values to require minimum adjustment.)
