A friend of mine owns a Mitsubishi cs-1952R (or is it 1953R?)
TV which is connected to the local cable system.  Recently,
a station on the cable system has gone "blank."  No static,
just blank.  At least that's all I can tell.  What really
happens is that the TV, when trying to tune the channel, shuts
down the video and audio.  The power to the TV is still on,
but if channels are changed, there is still no audio or video.
Everything is restored to normal by turning the TV off for
longer than 5 seconds and then turning it back on (on a
different channel).  My question is, what is in the signal
at that channel that causes the TV to shutdown the audio and
video?  I can hear a relay or something in the TV switch
the cause this, so I assume it is some kind of protection
for the TV; which sounds like some unhealthy condition exists
on this channel.  I haven't been able to contact anyone with
any knowledge at the cable company yet.

Any info would be greatly appreciated.
