My 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.
Turn off CEC control on the TV. If that doesn't fix move the 5000T to a different HDMI port on the TV.
Maybe 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.
Same for me turn on box, switches on TV automatically no signal. Turn off then on again work's perfectly. Hisense tv

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.

Traditional "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.
