Adjustment procedure
(1) Start adjustment at the center of the screen.
(2) Continue adjustment at next closest position.
(3) Adjust center area first, and ending with edge sections.
(4) Press the INPUT button to perform interpolation operation.
This process will take about 1 second and no picture will be seen at this time.
(5) After interpolation, check convergence again and repeat (1)-(5) if necessary.
(6) When convergence is acceptable, press D to write data to ROM memory. ROM WRITE? is displayed to alarm
system that ROM will be overwritten with new data. Press the D button again to write displayed data to ROM.
(7) DATA WRITE TO ROM will take approximately 4 seconds and no picture will be displayed.
(8) Green dots will be displayed when operation is complete.
(9) Press MUTE or any button (A,B,D MENU INPUT and AV Mode) to return to convergence pattern, then confirm
again convergence is acceptable.
(10) Press INPUT for 3 seconds more, convergence adjustment mode will be returned to C01 of service mode.
Notes: (1) Display only green for easier adjustment and match to jig screen. Press "ENTER", THEN PRESS 100/
ENT. (Use green to set raster position and correct for distortions.)
(2) Perform interpolation and data write to ROM after green adjustment. Once green has been confirmed to
match jig screen, the jig screen can be removed. Do not readjust the green color after jig screen has
been removed. This is now your reference color.
(3) Display green and red only and match red to green.
(4) Display all colors and match blue to green and red.
Touch-up red color if necessary.
(5) Existing DATA in ROM can be read by pressing the C button 2 times. This data can be used after
replacing a component (CRT, DY, etc.) Where complete convergence adjustment is not necessary be
careful not to overwrite this data.
DO NOT write cleared RAM data into ROM or a complete convergence adjustment will be necessary.
Remember to try with Existing data before starting convergence adjustment to minimize adjustment
time.
(6) Access for (3x3) mode. With the TV set off (AC Line off) Short circuit the located S6501 using a wire,
and then press the power button (AC line on before press). This operation will clear.
Note : All stored convergence data settings.
