Five Steps of Regular Troubleshooting Routine
1 Power: Please make sure all devices are powered on. (source, extender,
display devices)
2 Indicator: Please make sure LED indicators of transmitter and receiver are
normal according to user manual.
3 Devices: Please make sure picture can be shown normally when connecting
source to display devices directly.
4 Cable: Plug in and out HDMI/CatX cable or try another HDMI/CatX cable.
Cat 5e/6/6a/7 cable is recommended, do not use Cat 5 cable.
Please make sure CatX cable is less than 230ft for 1080P, 130ft for 4K
resolution.
Please make sure the two connectors of one CatX cable are same
standard (EIA/TIA 568B).
5 Compatibility: Please test other source and display devices to determine
whether it is a compatibility issue. There may be potential incompatibility
between source devices and 4KEX70-L(like Roku 4, Amazon Fire TV and
Cisco cable box). For more compatible extenders, we recommend 4KEX70-R
(Amazon ASIN: B01M3QVXS0).
