The LCD TV will occasionally lose its video display (while projector however works fine).
Solution:Basically, the tv has to stay off when you power cycle the webcam controller as below.
The webcam controller is located under the tv, on what looks like the webcam/speaker bar, on the left side of it.
Pull the cover off it and you'll see the box. To power cycle it, yank the power cord and count to 30 and insert the power cord back. However - TV has to stay off until the Ethernet link is up. If on the TV you see the blue message about initializing and acquiring ip, you'll need to turn off tv and power cycle again.
After successful power cycle with TV off, turn on tv and it should work fine.
