encounter with the LS-10d. If you encounter an issue not described here, please contact

connected to the LS-10d 
incorrectly or not at all. 

• The LS-10d is not plugged 

in or the AC outlet is not 
active. 

• Verify the HDMI cable 

connection from the DHD 
Controller to the LS-10d. 
Do not use a DVI cable 
for this connection. 

• Ensure that the LS-10d is 

plugged in and that the AC 
outlet is active.
