B-12. Double check focus performance the letters must be clear, legible and uniform, if not, repeat stape 2.3.2.1 to
obtain best focus performance.
B-13. Mi sconvergence alignment
B-14. Select crosshatch pattern and then input individually input R+B and R+G signals then measure and make sure
miscongence within Center = 0. 2 mm(max.)
Zone A = 0.3 mm(max.)
Zone B = 0.4 mm(max.)
, if not, readjust 4 P and 6P on the deflection yoke to get misconvergnce within specification. Preset modes alignment
B-15. Disconnect P103 before automatic alignment or connect P103 before manual
alignment.
B-16. Turn off monitor power and plug in P103 then turn on power again to get into factory mode.
B-17. Adjust H-size/ H-phase/V-size/V-center/ pincushion/trapezoid control s.... etc., to get geometric distortion within
specification as shown in engineering specification.
B-18. If raster center can't be adjust to get properly, P801 may sometime be necessary to reconnect in reverse direction
and then repeat step 2, 3, 4, 3 to get geometric distortion within specification.
B-19. X-ray protection test
B-20. Short P502 for 1 second at least to verify X-ray protection circuit is working properly.
B-21. Burn-in mode and power saving check
B-22. Turn off power, disconnect I/O cable and plug in P103 then turn on the power again to get into burn-in mode.
B-23. Turn off the monitor power and unplug P103 then disconnect H or V sync, turn on the power again to get into
suspend mode (power LED should indicating amber color), disconnect both H and V sync to get into off mode (power
LED should indicating amber color)
