TROUBLESHOOTING GUIDE

10

1.The power LED should turn RED when the correct voltage is applied to the Interface. It should turn GREEN when both power and a valid input signal is applied. If the power LED is absent when the unit is turned ON, return the VA6822 to the factory for repair.

2.Make sure the cables have the correct pin-out and the connection and quality of the cables is good.

3.Make sure that the source and display are scan-rate compatible. The projector should support an appropriate signal format (RGsB, RGBS or RGBHV). Connect the projector directly to a computer with a shorter cable to verify the compatibility of display and source.

4.If the desired output is in RGBS format, then the H&V Output dip-switch is in the OFF position and the Composite SYNC signal is taken from the HSYNC or CSYNC connector. If the display needs an RGBHV signal, then the H&V Output dip-switch should be in the ON position and the sync signal is taken from the HSYNC and VSYNC connectors.

5.If the desired output is RGsB, then the SYNC ON GREEN dip-switch should be ON.

6.If the image bends on top of the screen and RGBHV output is used, then turn on the H&V Output dip-switch.

7.Please make sure that the amplitude level of the input signal is as follows:

a)RED, GREEN, and BLUE channels are less than 1.2Volts

b)HSYNC & VSYNC are less than 5.0 volts

8.Please use only an ALTINEX supplied power cord suitable to the country of usage for proper operation of the VA6822.

9.If problems show up on the display after continuous usage at higher voltage, higher temperature, higher humidity, or at other extreme environmental conditions, please correct those extreme conditions.
