GENERAL ALIGNMENT INSTRUCTION

The Main PCB of Monitor Modification:

1. Input voltage is 6.8V-16V, input signal is test circuit BY 5418.

2. Adjust VRT5 to get test point: 15720Hz..

3. Adjust VRT4 to get horizontal phase shift.

4. Adjust VRT1 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 by VR, adjust video pattern’s color to white, test the screen

Brightness is 200±102 LUX.

With luminometer You can adjust R69 to get this standard.
