Testing
 
After finishing termination on both ends of the HDMI cable, 
use a Luxi HHT-200 HDMI continuity tester to test the 
cable and to make sure all pins are connected correctly. 
 
 
If some pins get crossed or shorted, cut off the end with 
problem and re-terminate it. 
 
Once pass the continuity test, connect the cable in the 
system to perform a signal test. If you see a normal 
picture on the screen and hear normal sound, the cable is 
good. 
 
 
Max cable length
The max cable length depends on many factors such as the signal data rate (resolution), source device 
signal quality, TV sensitivity and the compatibility between them. As a rule of thumb, this DIY ribbon 
wires typically should work for up to 12 m (40’) at 1080p signal rate. If the cable run is longer than 12 m 
(40’) or you do not get a picture after the continuity test, insert a Luxi EHD-111 HDMI Extender at the TV 
end in between the cable and the TV to extend the distance. The max distance with extender is up to 28 
m (93’) with 1080p signal. 
 
 
Troubleshooting
 
The Luxi DIY components are well designed and made. As long as the wires are inserted into the correct 
holes per the color coding on page 1, and drain wires are properly inserted to prevent sliding to the 
adjacent holes to create a potential short, and the wire slacks are reduced to minimum by sliding the wire 
holders as far as you can, the performance should be guaranteed by the design and better than the 
equivalent factory soldered HDMI cables. 
 
If the terminated wires passed the HDMI tester test, all the connections in the system are secure and the 
all devices are powered up, but there’s no picture or sound on the TV, try the simple steps below for 
troubleshooting: 
 
1) Lower the source device (Blu-ray player, cable STB etc.) resolution to one step lower, e.g. from
1080p to 1080i; if the picture or sound comes out on the TV, then most likely the problem you had 
before was bandwidth/cable length related. Insert the Luxi HDMI Extender between the cable 
and the TV to fix the problem.
