InactiveHello
I have the above Humax PVR and would like to know about something please!
I am getting a message on Screen ” The Terrestial Antenna is Short Circuited” now i cannot get rid of the massage .
I had reset the Box and by error had turned On the Antenna Power Option, now i cannot get to reverse that option to the Off .
When i try and do it all that now happens is that the Message gets sort of Highlighted ?
I have tried to switch off the Box, unplug it, pull out the Antenna, do all kinds of things but when re connecting and switching on again, the message appears again.
I have now taken the Box completely off which has taken that message away, so am sitting with no PVR.
Any Help will be most greatly received
Many Thanks for your time and for reading
Cheers

ModeratorHi and welcome to our Forum

We don’t have that unit in UK so cannot attempt to replicate your problem.
Have you tried another factory reset as this should default the antenna power option to off.

ParticipantIf Barries advice does not work. Connect to your aerial using an isolated wall plate. These have a series DC blocking capacitor.

InactiveThank you i have a wall plate already so that one is out!
As you dont have that Model on the site i am now stuck!
As for a Factory reset, i was looking at trying that but where on Earth do i do that, i cannot see anywhere that one can do a Factory reset??
Cheers

InactiveI have just come across this i wonder if it will work ?
Please go Menu-Settings-Power Management and see if Automatic Power Down is On. If it’s ‘On’ and HDR-7500T is left with no control for 3 hours, it is set to turn off itself to save energy.
So as my Set has been off now for overnight i will have to try it again and see
Thanks again

According to the user manual:
Menu
Settings
Installation
Factory Default
Default password is 0000 (4 zeros)
If similar to UK units you will lose recording schedule if you have one so make a note.

You do not need a wallplate. Just connect one in the coax feed from the box rf out out the the aerial which is clearly loop dipole device which is a short circuit to DC power. It’s not to radio frequency frequencies.

InactiveWhen i choose Installation after Settings all that happens is shown in last Picture, it just makes the Message have a white border and nothing else happens ????
Gosh this is so frustrating!
Done the above and still the same !

ModeratorIf you cannot enter 4 zeros at installation page you are stuck.
You could try uploading software to see if the will force a reset to system installation:
https://au.humaxdigital.com/support/?product_id=2688&curr_page=sw_release
Failing that contact Humax Australia support:
https://au.humaxdigital.com/contact-us/
Thay may have a default file you can upload to unit.

InactiveImprobable suggestion, but you could try starting a new installation with nothing plugged into the aerial socket on the box to see what happens then.

InactiveWell somethimg strange happened now!
I was just sitting and looking at the Box and on the Front Right hand side there are 4 small Buttons, Volume Plus and Vol Minus, then there is a -P1 and a +P1 now tapping one of the Buttons, suddenly the TV came alive , a Picute was showing, the message was there for a very short time and then it vanished!!! Very very Weird!
Anyway now could reset the Box again as there were many channels that i could not get and showed up as Weak Signals, so Re Scanned the Box and now Wallah! All seems to be back to normal! Holding Thumbs that it will now all be AOK!
Thank you s much though for all the suggestions, this is all so weird!!!!! Cheers Back to watching TV again! LOL
