signal problem dvb-T2 with V7 PRO

[frarosso]

Hi,

I bought a V7 pro, loaded the new firmware but I got reception problems with dvb-T2 channels both before and after.
First, with the automatic search I found less channels than with a v7 plus (I already got) and several channels have a bad signal. Besides I cannot switch to ON the Antenna POWER setting. When I try to switch it ON I get a popup message "Antenna shortcut - OK" than the Antenna POWER setting return automatically OFF. It could be the problem of bad signal. I have also some snapshot in attach. Do you know someone I can contact to solve this problem?
Regards

You can send me a private message directly,
1. Check if the antenna you are using is short-circuited, it will prompt
2. Does the DVB-T2 antenna have power?
3. You need to turn off the 5V antenna power supply, the load is too large, and the output voltage exceeds 5V

Hi,

I have also a gt media v7 plus and the settings are identical.
If I remove the antenna cable from v7 pro and put in v7 plus all works fine, I can switch the antenna power setting to ON,receive more channels and all channels are of good quality.
So there are two chance
1- it is a software problem
2- it is an hardware problem

I don't have a powered antenna, I put in the cable from the wall. As I said g7 plus works fine

Maybe the problem is due to the cable... I will check it furtherly.
Anyway I saw that when the automatic scanning dvb-t2 Italy, the frequesncy 522000 is not scanned. Instead I see 000000

And why do You turn on the "antenna power" if you have it working without an amplifier? Set up the antenna, You may have poor reception. (GTMedia_V7PRO_Release_20200903)

My V7Pro is due today and I will test it on this asap.

I posted on the antenna power check function a while ago.

Have you tried working with the option antenna power check "OFF"?
