Smart tv buffering. All others ok on splitter

[just pumps]

The TV might be getting too much signal. With digital signals, this can create what looks like the same issue as low signal strength/quality. What happens is that when the signal is too strong it overloads the tuner and it looks like the Quality measure goes down. The fix for this would be to use an attenuator to reduce the signal power going to the TV

Thinking this may apply to my problem so would you please have a link to an attenuator that you`ve used before and would it matter where it is fitted?

Right. Problems again.

signal very poor and bit error 2000 showing

I checked the cable and there looks like a short.

did you sort out the short in the cable
Did you use a multimeter on the connections?

yeah I disconnected the cable from the booster end and the socket end and tested for a short and it was clear.
Put it back together and it was working fine but then today it started the poor signal again.

Toolstation has branches throughout the UK. They sell the PROception 1~20dB variable attenuator. Being adjustable means you can dial in the appropriate level of signal reduction.

Its just a fiver too, so not expensive.

You'll notice from the picture if you follow the website link that it has the screw-on satellite-type F connectors. That might phase some folks because its not a standard aerial-type connector, but depending on where you'll fit it, this could work out to your advantage.


For any point in your system, be it before the aerial distribution system, or before a TV recorder, or just simply before the final connection to a TV, you can cut the coax and fit F plugs really quite easily. The attenuator then fits in line.


If you prefer, a quick Google search should result on finding versions with standard female and male TV coax connections.


Where to fit:
If it's only a problem with one TV then apply the signal reduction just be the aerial socket on the set.


For issues affecting several TVs, apply the attenuator on the aerial feed before it goes in to any aerial distribution amp.


Some TV recorders boost the strength of the aerial signal from the RF loop-through. The recorder might be fine but the TV overloaded if the strength was already close to maximum before adding the recorder. In theatres case either fit it between the recorder and TV, or before the recorder.


All of this presumes that you have standard sized RG6/WF100 aerial coax at roughly 6.5mm diameter. Where you're using one of those TV aerial cable extension kits sold by supermarkets, DIY sheds, Argos etc then I would ditch that first and replace with good coax before experimenting with attenuation.

Nice one Lucid, I`ll return with an update but might be a while as I sent the TV back to be checked out under warranty.

Digital signals have very abrupt cut-off points. Where the signal is marginal for some reason, then it only takes a very minor change to make or break the TV picture.

You've done the troubleshooting and ruled out a fault with the amplified splitter and the continuity of the coax cable itself (excluding the plug ends). What remains then is either related to your reception locally, or it's damage to the cable such as crushing of a kink, or the fitting of the plug ends themselves, or a TV fault.

Swap the TV for a known good one to see if that's the same. Buy a long length of coax and feed the TV from a know good socket. Try making the plug ends again.

Other than that, there's not really much more we can do based on the info you have supplied so far. Its time then to get a local aerial guy in to sort the issue.
