Mike,

I read what you state but,

It is a little surprising that corrosion/ oxidation should happen on 3 TV,s at the same instant.

It also does not explain why I have been receiving on PSB1 this evening but not channels on RSB2.
Or that
Yesterday there were no channels on PSB1 or PSB2 showing but first thing this morning I have all channels.
I will give your suggestion a try tomorrow after I have checked all channels.

Mike,
Just to update there were no channels on COM5 either last night. This morning we now have all channels on PSB2 which we didn't have last night but now no channels on PSB1.

This must surely be a transmitterpower issue and not aerial issue in the home.

Robin Mutch:

That clearly shows that there is a problem with your aerial system. It could well be in the part that is common to the feeds to you different TV sets, i.e. before any splitter or distribution unit.That is the area yoiu need to examine closely but do be careful if you need to access any external parts.

The fact that it affects some multiplexes but not others and varies shows it is almost certainly oxidation at a connection/joint that is causing the problem. Such faults are very frequency selective and is a well known problem in the trade.
