InactiveMy Samsung telly loses TV signal when my Humax 5000T is powered on – switching off the 5000T restores the TV signal. If there was no signal with the PVR switched off then I’d understand, though I have eco-mode switched off in the 5000’s settings.
Can anyone explain why this is happening? My 5000T was purchased with the latest firmware already installed.

ParticipantTurn off CEC control on the TV. If that doesn’t fix move the 5000T to a different HDMI port on the TV.

InactiveMaybe once the Humax is on there is interference from the HDMI cable into the TV’s aerial cable. Try moving them as far apart as you can.

Did that and it seems to have made a difference. Time to replace the HDMI cable I think.

HDMI cable replaced and moved as far away from aerial lead as possible, but it’s still an issue although now it’s intermittent when the Humax is powered on.
Could my FVP-5000 be faulty? Surely it shouldn’t be generating so much interference that it affects the TV signal?

HDMI cables generate RF in the UHF band, it’s nothing to do with the box. If you have cheap poorly screened coax interconnects it can knock out terrestrial TV. Make your own coax interconnects using double screened satellite grade cable.
I use screw on f connectors and belling lee converters as needed.

Thanks for that, very useful.
So I should use double-screened co-ax between my aerial point and the Humax, and from the Humax to the TV?

Yes it can avoid interference from HDMI interconnects which radiate radio frequency interference in the same band (uhf) as terrestrial TV as described above. However I would use a splitter to give the TV and Humax box a seperate feed. That way you can turn on power saving in sby mode.

InactiveTraditional “brown TV coax with copper braid” is virtually useless for Freeview signals. Analogue TV signals were very tolerant to interference – remember those pictures which were more snow than picture?? – but digital is much more sensitive.
Traditional TV coax is useless because the braid is so open it lets all sorts of interference through.
Use satellite grade coax with a braid AND a solid metal foil sheath.

The coax cables from the TV aerial point to the Humax and from there to the TV are just flexible TV signal cables, don’t know how well they’re shielded. Are you suggesting I use solid core coax instead of the one’s I just mentioned?

WF100 is available in a range of colours including brown.
The key is solid copper centre core, foam dialectric, copper foil over foam dialectric and copper braid foil.

No he is suggesting you use satellite grade cables. Not all satellite cabling is the best choice. Avoid steel copper plated conductor and aluminium foil like RG6. Webro WF100 is the best in the 100 grade though PF100 will be fine for indoor cabling. See the above post.
Avoid using the cable with air spaced dialectric outdoors because it makes an excellent water pipe into your connected kit.

note the foil under the braided screen.

Use this stuff.

InactiveJohnH77 – 22 hours ago » Traditional “brown TV coax with copper braid” is virtually useless for Freeview signals…
I guess in some circumstances that is true. However, back in analogue days my house was cabled with brown co-ax to every room for TV and VHF. The signal is fed thru an amp/distributor. I rarely use Freeview since I have Freesat but on 4 TVs my Freeview signal is excellent. I don’t doubt I could probably improve it with WF100 (which I have cabled satellite in) but in my case your assertion does not hold up.
