We have Shaw Blue Curve TV.

We have 2 televisions.

One has the PVR and it works without any problems.

The other TV one has a small box.  Lately we are having a problem with this TV, it keeps cutting out  (both video and audio) for a few seconds and then coming back on.  This is very annoying and makes it difficult watching TV.

First I thought  that TV was the problem, but we happened to have another TV around, so I hooked it up, but no joy- the problem is still there.

Anyone have any ideas?

Thanks,
