6. Troubleshooting & Maintenance
1) When images of terminal unit output with ghost, such as the projector output with
ghost. Generally this is not a unit faulty, this may be caused by an incorrect setting
on the projector or a bad quality of cable. Please check the projector’s setting or try
another high quality connection cable.
2) When there is a color losing or no video signal output, please check the input and
output end connections of the cables.
3) When there is no output images:
Check if there is any signal at the input.
Check if there is any signal at the output.
We can check these by using an oscilloscope or a multimeter. If there is no signal
input/output, maybe the input/output cables broken or the connectors loosen,
please change for another cable.
If not the problem mentioned above, probably there is something broken inside
the unit, please send it to the dealer for repairing.
4) If the POWER indicator doesn’t work or no respond to any operation, please make
sure the power cord connection is good.
