Please unplug between the source and the HDBaseT Tx unit, that will force a hotplug reset of the DTV box.
We unplugged between the source and the TX unit. This did not cause the extender to relink (i.e the "Link" light on the unit did not turn on and the image did not come up on the TV.)
Only power cycling the TX unit seems to (temporarily) solve the issue, so far.
