Low signal quality ee tv pro box

[Ianhutson08]

Hi,

We are experiencing low signal quality on the tv pro box (both boxes we have been sent) and our previous bt pro box too. Signal strength is good, around 90 to 100 percent but quality is poor at around 20 percent (max 30 percent) 

The odd thing is that a bt engineer left me with a bt 4k uhd box and with the same cables and set up it shows 100 percent quality on every channel. I have tried an old youview box which also shows 100 percent quality. 

Pulling my hair out as to why the pro box would be giving such poor quality vs the non pro box. 

Thanks

Ian

You are running the Box Pro in Aerial Mode?

Good Strength but poor quality can be a sign of signal overload, as if the aerial were SHOUTING; if you have, and can try, a variable attenuator in the aerial chain, this may fix it.

However, given that the other boxes are OK, I might suspect a faulty Box Pro. Give it a Factory Reset, and if that doesn’t fix it, ask EETV to check it out remotely from possible replacement.

Hi Midnight_Voice

Thanks for the reply. Yes, it's in aerial mode 

I had purchased a attenuator and reduced the signal strength down from 100 to around 85 but the quality is still very low but only on the pro boxes. No problem with the non pro ones.

I have also tried a few resets and nothing changes unfortunately, it's consistently low quality. 

I would suspect a faulty box, however,  we have had 3 (one older bt one) and two new EE ones and they are all the same.

Indeed, as you describe,

Mystifying….

But you are comparing apples with apples? The issue happens when you swap a Pro box onto the exact aerial cable that is fine with an earlier box, rather than using two different aerial cables/routings, and just assuming that you don’t have a setup where some aerial cables are good, and others aren’t?

If you haven’t tried physically swapping a Box Pro with one of the earlier boxes while keeping all the wiring the same, try that now and report back.

@Midnight_Voice 

Yeah, all the same cables and set up, just moving them from one box to the other. 

I would keep the older box but that does not support netflix with adverts 😅

@Ianhutson08 

Puzzling then.

I can  vouch for my Box Pro and Mini working pretty much identically to my DTR-T2100 and DTR-T4000 in this respect; I will sleep on it, and see if anything occurs to me.

Should we be considering possible electrical interference  causes ?

[Midnight_Voice]

@zulu17 

Indeed yes, if you think that a Box Pro in a certain location might be vulnerable to interference that an earlier YouView box might not be,

We know that the older boxes don’t like plasma TVs and LCD lamps; perhaps the newer boxes have a new bête noire?

The little man who lives in my head and works tirelessly on problems while I sleep asks what happens if you loop through from the aerial outputs of these boxes to the associated TV set(s); is the onward signal similarly affected? As it’s not just a passive loopthrough; some amplification of the input aerial signal is involved.

@Midnight_Voice 

Only looking at possible causes as seemingly the more probable causes get discounted.
As the problem experienced with several EETV  Pro /BT TV Pro boxes an individual box issue seems unlikely.

Maybe the cable setup , perhaps different screening tolerances  .

The box pro with its 4 tuners as opposed to the Older Humax  boxes dual tuners is one clear difference between the boxes that do and do not experience the problem here.

One thing I would try is turn off TV and any other nearby  TV devices and setup a recording  Then see if the quality of the recording when replayed back is good or impacted quality.

[Ianhutson08]

Thanks for the ideas, I have run through them all to no avail. Tried different cables, tried recording with everything turned off. Issue still remains. Channels that are showing 100 quality on the older box are unwatchable on both box pro boxes. 

Unless I am incredibly unlucky and have two bad boxes it must be something different with the tuners on the pro not liking my setup. Bizarre.
