Channels disappeared

[IJWS15]

Carpet fitted in the lounge yesterday and since we were sofa-less moved the recorder into the conservatory.

Moved everything back yesterday afternoon and the tv in the conservatory (Logic) the tv in the lounge (Panasonic) and the recorder (Panasonic) have all lost channels. Tried retuning several times and sometimes the find nothing. E.g initially lost all bbc and last time the first channel was no 25!

We are on Freeview with a roof aerial and a multi output booster in the loft, none of this and none of the aerial cabling has changed.

The TV in the study that hasn’t been disturbed is still fine (was last night)

Now how do I restore everything

Try the recorder in a room that hasn't been disturbed. Is the aerial cable running round the edge of the carpet? has the fitter damaged it in some way?

double check the cables, just because they worked before does not mean they didn't get damaged when removed.

Made a new cable up for the conservatory which made no difference. Retuned the conservatory tv in the study (all channels I expected found including BBC), took it back to the conservatory and most of the channels can’t be found (including BBC) - shows no signal.

Hard wired from the amp to wall sockets and loose leads from there to the tv/recorder. One could be a cable but why would two go at the same time.

Thinking about replacing the amplifier.

.

Poorly constructed cables, damaged whilst unplugging them. Or connections behind the wall socket. Or just cheap plugs.

Signal in the lounge restored, conservatory still refuses to do anything. I did change the amp as it was installed before we bought the house 18 years ago, I don't think it made any difference.

Will have to get another lead, made a couple up last night and nothing, at one stage it was picking up the Rakutan channels but nothing else! Will have to get an new lead or some more cable and connectors.

This is starting to annoy me. Took the conservatoty tv to the study and retuned it. Took it back to the conservatory - nothing.

Nothing from 3 brand new leads.

Pulled some slack through on the feed to he socket and put a plug on it, connected to tv using a known good video to tv lead (f-m) - nothing. Straight into back of tv - nothing.

Swopped sockets on the amp - nothing, thinking it must be the fixed lead but b******** if I know why as that wasn’t disturbed until after the fault!

Try connecting the aerial directly to the conservatory TV, bypass the distribution amp. You'll need a joiner or similar. Sometimes too much signal can overload a TV tuner.

What sort of 'amplifier' do you have, if you know? Is it a mast head amplifier, ie a small white box in the lounge (or another room) that plugs into a power socket and the has a lead going into it and out of it, but crucially, sends power up the cable to another amplifier in the loft, which distributes the signal around the house...this is highly likely the set up.

If so, the white box is just a power supply for the box in the loft and does nothing to the signal. If the box in the loft is faulty then this will cause signal issues to one or more of it's outlets. Cheap to replace. Example on link.
