4 Troubleshooting

4-1 No Power

When Pin 4 of CN600 is 0V

does proper DC 5V, 14V

appear at Pin 6, 7 of

CN600 separately?

Change IP Board.

Check Function Ass'y.

Yes

When Pin 1 of IC601 is DC 5V

does proper DC 3.3V appear at

Pin 3 of IC603?

Check IC601 and related circuit.

Yes

When Pin3 of IC602 is DC 5V

does proper DC1.8V appear at

Pin2 of IC602?

Check IC602 and related circuit.

Notes: 1. Before troubleshooting, setup the PC 's display as below.

• Resolution: 1440 x 900

• H-frequency: 45 kHz

• V-frequency: 60 Hz

2. If no picture appears, make sure the power cord is correctly connected.

3. Check the following circuits.

• No raster appears: Function PBA, Main PBA, I/P PBA

• 5V develop but no screen: Main PBA

• 5V does not develop: I/P PBA

4. If you push and hold the " (Enter/Source)" button for more than 5 seconds, the monitor

automatically returns to the factory preset.
