1. Memory problem

If you hear a long beeping alarm sound when you start the computer, this may mean that there is a problem with the memory.

First, turn off the power of the industrial computer and unplug the memory stick.

Use an eraser to wipe the gold fingers of the memory stick to remove possible oxides or dirt.

Reinstall the memory stick into the slot and power it on again.

Observe whether the monitor displays. If the problem persists, you can try to replace the memory stick to another slot, or replace the memory stick of the same model for testing.

2. Keyboard indicator light and discrete graphics card problems

If you do not hear the alarm sound when booting, you can observe whether the keyboard indicator light is on. If the keyboard indicator light is on, it means that the industrial computer starts normally.

Check whether the display interface is connected correctly and make sure that the discrete graphics card is not inserted. Sometimes inserting a discrete graphics card will cause display problems.

If the keyboard indicator light is not on, it means that there may be a CPU problem.

Try to remove the CPU, use an eraser to clean the gold fingers, and reinstall the CPU for testing.

If the problem persists, you can consider replacing the CPU of the same model for further testing.

3. BIOS setting error or failure

Sometimes, incorrect BIOS setting or BIOS failure can also cause the monitor to have no output.

Turn off the power of the industrial computer and disconnect the power cord.

Open the case and find the CMOS battery on the motherboard.

Use appropriate tools to remove the CMOS battery and leave it for a while to fully discharge.

Reinsert the CMOS battery into the slot and install the case cover.

Reconnect the power cord and turn on the power.

Observe whether the monitor displays. If the problem persists, please contact the after-sales service center of SINSAMRT Industrial Computer for further technical support.
