    Default 2x TVs HD Channels. Same room, same aerial, different results.

    Before I start, both of these TVs have DVB-T2 tuners and are both 4K Ultra HD.

    Bought a Samsung UE70RU7020KXXX on black Friday. Delivered yesterday. Have a Panasonic TX58DX750B delivered 2 years ago.

    Happy with both especially the Panny. Just thought I'd treat myself to a larger screen, as you do.

    The Panasonic works flawlessly and although I've had HD channels work on the Sammy, they keep vanishing without explanation.

    Check this video out and if anyone has any ideas before I officially send it back, I'd love to avoid doing so.

    Aerial is new and was professionally installed and gives 94% quality, 100% Signal and 0 BER.

    Sammy of the Left, Panny on the Right.

    Going through a booster?
    Im not sure but if you dont have a booster or splitter without a resistor or coil the tv's inbuilt booster will cause problems with other tv sets.

    Grab one of these onjly a couple of pound

    No booster involved, not needed as I'm in the same town as the Freeview transmitter (Sudbury - [Only registered and activated users can see links. ]).

    Only setup both at the same time to show the difference. Happens with a direct feed to the TV too. Panasonic finds all the Freeview HD channels, the Samsung doesn't.

    I'm quite confident this is a fault with the TV because it has found them a couple of times, then loses them within an hour.

    In which case yes if it’s losing the channels I would say send it back.
    have you called them up?

    samsung can remote to the tv and see any issues.

    I tried to call them, but was left hanging for about an hour. Will try again tomorrow, but Very have agreed to collect it if Samsung can't do anything, their Web Live Chat is pretty rubbish to be honest.

    Just tried to convince me it weren't faulty and was my aerial even though I explained my Panny doesn't have a problem.

    I'll see if Samsung can entertain me tomorrow.

    Do a Google search and see if anyone else with same TV is having same issue
    More ammo to throw at them when you call them

    You could have too much signal which is flooding the tuner on the samsung and not the panasonic, you could try an attenuator which come in various -db ratings starting at -3 going up to -18

    I took the opportunity to fiddle with this today. After messing about with few different actuators, I'm pleased to confirm, my TV is working great now.

    Thanks guys for suggesting lowering the signal, seems it's done the trick.

    Who knew there was such a thing as having to strong a signal!? Wow.

    I might try that myself. My samsung tv sometimes drops the HD channels. I assumed it was because I'm on a communal aerial that was too weak. Could be just the opposite!

    one strand of braid around the centre core may suffice IE short it slightly
