5. COMPLETE MACHINE GENERAL ADJUSTMENT
5-1 Go to factory mode according to 4-4-2 before warm up line.
5-2 Focus Adjustment.
5-1-1 Receive monoscope pattern.
5-1-2 Set TV to work in dynamic status.
5-1-3 Adjust the focus knob of FBT to get the clearest picture.
5-3 Screen Voltage Adjustment.
5-3-1 Go to factory mode "MENU 2" status according to 4-4-2.
5-3-2 Select "V-KILL" by pressing "CH+" or "PROG+" and "CH-" or "PROG-" keys..
5-3-3 Press and hold on the "VOL+" key all the time, Adjust the screen knob of FBT to get a horizontal
faintness beam line. Then release "VOL+" key.
5-4 White Balance Adjustment (Applied in factory only)
5-4-1 Set the TV set to AV mode. Receive black white pattern (Color Temperature test pattern).
