Channel 5 dropping off tv in Kitchen

[foxhole]

Keep losing channel 5 on one tv, retune and it's found but only lasts a few hours before disappearing?
No other channel affected, still get channel 5+1 on affected tv, have three more tv's fed from same aerial [two from same splitter] and no problems.

Please remember this is a guess so could be wrong. My parents had the same problem and I realised that Channel 5 Multiplex for their area was Channel 68. So when neighbours Sky box was used this transmitted on same channel so they lost signal.

When I looked there were many other channels using the same Multiplex frequency but they did not watch those so did not know they had lost them.

So look at anything with a RF output. Video games, VCR, DVD likely something else transmitting on the same frequency.

In the days of analogue it was easy you could see the other signal so when you saw the bat and ball going across the screen it was easy to work out what it was. But digital can't see analogue and analogue can't see digital but they can still stop each other from working.

Move that TV to a different room where the TV is working OK. Connect the aerial and see if the fault occurs. If it does, the TV itself is faulty.
Otherwise report back here.
