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 text -

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