To check if the computer’s HDMI is malfunctioning or not, follow the troubleshooting 
procedures below as instructed. 

Procedure 1:  External HDMI Monitor Check 

Procedure 2:  Connector and Cable Check 

Procedure 3:  Replacement Check 

The HDMI port is connected to system board. If HDMI malfunctions, its connection is 

defective and system board may be faulty. 

Check 1 

Make sure HDMI cable is firmly connected to the connector CN15/CN17 (system 
board). If the problem still occurs, perform Procedure 2. 

 

Connect an external monitor to the computer’s HDMI port, and then boot the computer.  The 
computer automatically detects the external monitor.  

If the external monitor works correctly, the internal LCD may be faulty. Go to Procedure 3. 

If the external monitor appears to have the same problem as the internal monitor, system 
board may be faulty. Go to Procedure 2.
