Need help to diagnose - Is this the result of poor quality aerial?

[skyripper]

Mother-in-law's telly broke few months back. She bought a new LG. Hates it because it's complicated.
She only watches terrestrial telly.


Its recently been doing this on regular occasion and only fiddling with the aerial lead seems to cure it.
When it goes like this, the sound still comes thru, but is occasionally crackly.

Is it worth an aerial booster, or am I going to need to crawl about in the roof and see whats going on up there?
She's mid 70s, in poor health and 40 miles away. Which makes popping over there to try stuff a bit difficult.

Looks like digital breakup which is normally caused by bad signal.

Could be as simple as the aerial lead into the TV is old/damaged and was disrupted when the TV was swapped.


If you do need to replace the aerial (and to be fair if it's of unknown age, it may even predate digital transmissions and not be optimum anyway) - I thoroughly recommend a Log36 Loft Kit from Aerials and TV - https://www.aerialsandtv.com/product/aerial-kit-loft-mount

Also plenty of useful information on their webpage regarding aerial choice, and other topics.

I have something weirdly similar sometimes.

Brand new shiny Panasonic OLED, strong signal area, plugged aerial in and dodgy signal quality.

After much head scratching, trying different cables, and being convinced it was an issue with my aerial wall socket, turned out it was something from our Roku that was plugged in causing interference.

Moved the Roku away from the cable a bit and it cleared up, 100% signal on every channel now.

Was driving me crazy wondering what it was causing it.

So is there anything else plugged in or nearby that could be causing interference?

cheers all, I'll take the suggestions back to the MIL, but suspect in the next few days, there will be a 40 mile trip to install a modern aerial in the loft...
