GENERALALIGNMENT INSTRUCTION
The Main PCB of Monitor Modification:
1. Input voltage is 6.8V-16V, input signal is test circuit BY5418.
2. Adjust VRB1 to get test point: 15720Hz..
3. Adjust VRB2 to get horizontal phase shift.
4. Adjust VR1 to get good performance.
5. Adjust S201. S202 to get good Tint.
The main PCB of DVD Modification:
1. Adjust the brightness to the brightest byVR, adjust video pattern’s color to white, test the screen
Brightness is 200±102 LUX.
With luminometer You can adjust R250 to get this standard.
