I've been observing a phenomenon that's puzzling me. I have an
analog TV connected to a DTV settop converter (Zenith DTT901). For
the most part, it works fine.
But every so often the program I'm watching blinks. Every few
seconds the picture blinks black. No corresponding breaks in the
audio.
It only does it on certain channels, at seemingly random times.
Switching to another channel gives an unblinking picture. So this
tends to rule out the converter box, even though it *could* be
blinking just on that one channel (but why?).
And if the station is putting out a blinking signal, you'd think the
station would notice this and correct it.
Anyone else seen this?
Sure your signal is not dropping out at the antenna?- Hide quoted

I would try another setup using a different antenna or convertor,
borrow or swap one with a a neighbor.



Bear in mind also, that digital TV reception is not *just* about
signal strength. The digital sat receivers here in the UK, have twin
on-screen signal meters in service test mode. One of these is for
signal strength, and the other is for signal "quality", which is a
measure of the determined bit-error count. I have on many occasions
seen misaligned dishes that give a good 70%+ signal strength
indication, but only a 50% quality reading. My terrestrial DTV signals
are a bit 'iffy' at some points on my distribution network. The signal
to the kitchen is one example. The LCD TV in there has a signal
strength meter which pops up for a few seconds whenever you change
channel. This seldom shows below 70%, but this set often suffers from
all sorts of odd problems, including pixellation, total freezes, and
an on screen message saying that no programme is available on that
channel, even though the meter showed a good signal level. I suspect a
cable drop issue and standing waves on the drop, but it only occurs on
some channels, and the TV is not used enough to warrant the hassle of
running down the cause of this 'problem'.

I have two different US DTV converters,and the signal meters only measure
signal strength,not "quality"(bit error rate?),and they are different in
their operation and response.

Mine drops out depending on where my upstairs neighbor is at the time. :-(

He should go on a diet!
