5 Troubleshooting

Notes:

1. Before troubleshooting, setup the PC’s display as below.

• Resolution: 1280 x 768
• H-frequency: 61 kHz
• V-frequency: 75 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/D PBA
• 5V develop but no screen: Main PBA
• 5V does not develop: I/D PBA

4. If you push and hold the “ (Enter/Auto)” button for more than 5 seconds, the monitor automatically returns

to the factory preset.

5-1-1 No Power (GS15M*)

When Pin 4 of CN600 is 0V

does proper DC 13V, 5V

appear at Pin 1, 2 and 6, 7 of

CN600 separately?

Change IP Board.

Check Function Ass’y.

Yes

When Pin 3 of IC602 is DC 5V

does proper DC 3.3V appear at

Pin 4 of IC602?

Check IC602 and related circuit.

Yes

When Pin 4 of IC600 is DC 0.3V

does proper DC 3.3V appear at

Pin 5 and 6 of IC600?

Check IC600 and related circuit.

Yes

When Pin 2, 3 of IC601 is

DC 3.3V does proper DC 4.3V

appear at Pin 1 of IC601?

Check IC601 and related circuit.

Yes

When Pin 2, 3 of IC601 is

DC 4.3V does proper DC 2.5V

appear at Pin 4 of IC601?

Check IC601 and related circuit.

❇

* 0V means power on state.

When the monitor work well except DPMS and power switch off,
0V should be applied to number 4 of CN600.
