Sirs,
I have LG OLED 55" TV. Couple of months ago the on UHF 55 started pixelating and sometimes the channels disappeared completely. All other channels are OK and shows 100% for both strength and . Can you kindly investigate the problem and advise? Quality on UHF 55 channels fluctuating between 0 and 45%. The problem is serious for me as it involves BBC 4 and BBC news HD (106,107) which are my favorite.
Kind Regards

Milan Navara:

Your predicted of all multiplexes is excellent, including COM7 on . Check that your still looks intact and pointing in the correct direction - bearing 80 degrees for you - slightly N of due E (which is 90 degrees). The rods (or squashed Xs) should be horizontal. You could also do a comparison to neighbouring aerials.

Have you moved anything or introduced any new equipment? Make sure you do not have any HDMI leads close to poorly screened aerial or flyleads. HDMI has been know to cause especially to C55.

Check all aerial connections and swap any flyleads which can often go faulty with intermittent connections not necessarily affecting all multiplexes.

Since this started a couple of months ago, some other possibilities could be - any trees nearby on the line of sight which have come into leaf and/or grown taller, any close-by scaffolding or other building been erected or possibly a new mobile phone quite close by in the direction that your aerial is pointing.

I completely lost everything on CH55 a couple of weeks ago. It used to be a bit flaky now and again, but now I get nothing. All other are fine. It's as if it's been switched off. I'm in Holborn if that makes a difference.

Yes location can make a big difference to reliability of . Without a full postcode we can't say what your predicted reception would be.
Have you tried a manual retune on ?

Other than that, see my previous reply to Milan Navara, now at the bottom of p134.

I have so many issues with the TV in Whyteleafe South, I get no as I live in a flat and the management charge the leaseholders Circa 21,00 per year and yet the is so bad. Tonight I can't get any to work SD or HD or radio. Started at 9 pm. Can we not just get rid of the aerials and have all the TV come down the internet with less and better for the broadcaster and consumers of the service. TV aerials are so old hat today and cause too many issues. Let's fix TV signals - we can fly a man or woman to the moon, we can call from one end of the earth to another but we can't get decent tv signals across the country. Its a disgrace. CR3 area

Sam :

You should get very good there from the , virtually due North of you.
Have a look outside and check that the is still there, looks intact and pointing in the correct direction with its rods(or squashed Xs) horizontal.

Apart from checking all your own coax plugs and connections, if the aerial has been damaged by this recent bad weather or the situation does not improve then your really need to complain to the landlord. I assume that it is covered in the tenancy agreement!

I can't find any current fault reports, but then those for commercial multiplexes are almost impossible to find.
Is the problem still continuing?
