4-1

4 Troubleshooting

Notes:

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

• Resolution: 1024 x 768
• H-frequency: 48 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: Audio PCB, SMPS PCB, Main PCB
• 12V develop but no screen: Main PCB
• 12V does not develop: Audio PCB, SMPS PCB

4. If you push and hold the “EXIT” button for more than 5 seconds, the monitor automatically turns back

to the factory preset.
