A message has appeared saying ‘antennae has short circuited’. The picture is still very clear but the sound is now muffled and fuzzy. I have taken out the cable going into the antennae slot and restarted the machine but noise is still there. Is there anything I can do without buying a new machine!
I have done this – but still the sound is fuzzy. Anything else I can do?
Welcome to the Forum
Check to see that the connection between the Humax and TV has not been disturbed, ie the Scart/HDMI leads are fully inserted.
Have done what you suggested – still the same. Even tried watching a previous recording from the hard drive – also voice fuzziness! Anything else I could do or do I have to buy a new unit – don’t really want to!
It could well be the TV. How is the sound using the TV’s tuner or a different digi box?
Humax model is PVR-9150T and it is just over 2 years old.
The TV is working fine – no fuzziness in picture or sound. Only when the box is turned on does the sound fuzziness happens. Picture is not affected.
Turn down the volume on the TV. Turn up the pvr volume using the pvr remote control to full. Now turn up the TV volume to a reasonable level. How is it now ?
Have just tried your suggestion – still no change – fuzzy sound even louder. I guess this means that I need to get a new box or get it fixed which ever is cheaper!!!!
Now try the reverse turn down the pvr volume to say 25% and adjust the TV volume again. Trying to ascertain if the problem is either
a) too loud and overloading the TV audio amp input stage
or
b) too quiet and requiring the TV volume to be way too loud (last test proved this not to be the case).
Still got a few possibilities in mind but one step at a time.
Have turned the pvr volume down to 25% and tv volume up. The fuzziness is still there but the fuzziness is still there but a little bit better – you can actually hear the voices but not clearly.
Have you any other kit you can connect by scart to rule out the TV. If you have use the same scart socket and see if the sound is clear.
Hi Graham
I saw your reply to the original post about turning OFF the antenna power.
My Father has a 9300T which works perfectly I believe (no sound issue) but he DOES reguarly get the ‘antenna short’ message on screen when box is first switched on.
I have asked him to switch the power off as you suggest and in a few days we will know if this has resolved it.
Now if this was a Satellite box I could understand a voltage being ghosted to the antenna cable to power the LNB, but these are Freeview boxes. Do you know why there is an antenna power option and why does it default to on? Is it simply for an aerial amplifier?
Thanks

Afaik it doesn’t default to on. The option is there merely to provide DC power to an aerial with a built in amplifier or a seperate amplifier. It merely outputs a DC voltage which in the absence of an amplifier merely adds a DC offset to the rf signal (removed by the tuner or a isolated wallplate). Simple aerials with a loop (folded) bipole are a short circuit to DC anyway. Welcome to the forum from me
In this case he may have a errant whisker of screen in a badly fitted Belling Lee touching the core conductor. So in a way it’s maybe found an intermittent fault.
Dad probably thinks the option somehow increases the signal in someway. A pretty common mishaprension.
