Usb-tuner DVB-T/T2 suddenly(random) blackscreen when zapping

[superglud]

Often when zapping the Usb DVB-T/T2 tuners suddenly stop working.
The tuners are still activated but i get only BlackScreen, and i have to reboot the box to get them working again.

Is there any way to get them working, without having to reboot ?.
( telnet: restart usb-tuners, restart usb-system, etc. etc. ? )

Tuner C: Vuplus DVB-S NIM(AVL6222) (DVB-S2) - slot B
Tuner D: Vuplus DVB-S NIM(AVL6222) (DVB-S2) - slot B

As they work for software the usb-tdt hangs, only the inmates do not have this problem.
If the channel you see has little signal, pixel passes what you say, even if you stopped watching DTT and you're on satellite, the tuner usb-tdt continues working and blocks the receiver.
Always leave in a channel with good signal and most importantly, if you can improve the signal/quality of the channels, perfect.
Remember that the signal/SNR and quality/AGC that the usb tuners dial is not valid, they all measure poorly.
I repeat all measure poorly or do not measure.
Only the interns work well.
Good luck, verified with 3 tuner usb-tdt doubles and 5 singles this problem.
By the way, having more than 4 tuner vU + DUO2 blind search does not work, it seems that, but it really does not work.
In Astra it takes 5 minutes, now it will take 1 hour and at the end it will say that it does not find anything, you remove the usb-tdt, restart and now perfect.

Verified with 3 x VU+DUO2.

Como trabajan por software se quedan colgados los usb-tdt, solo los internos no tienen este problema.
Si el canal que ven tiene poca señal, pixela pasa lo que comentas, incluso si dejaste de ver TDT y estas en satelite, el tuner usb-tdt continua trabajando y bloquea el receptor.
Deja siempre en un canal con buena señal y lo mas importante, si puedes mejorar la señal/calidad de los canales, perfecto.
Recuerda que las señal/SNR y calida/AGC que marcan los sintonizadores usb no es valida, todos miden mal.
Repito todos miden mal o no miden.
Solo los internos funcionan bien.
Suerte, verificado con 3 tuner usb-tdt dobles y 5 sencillos este problema.
Por cierto, al tener mas de 4 tuner el vU+DUO2 no funciona la busqueda ciega, parece que si, pero realmente no funciona.
En Astra tarda 5 minutos, ahora tardara 1 hora y al final dira que no encuentra nada, quitas los usb-tdt, reinicias y ahora perfecto.

Verificado con 3 x VU+DUO2.
En español para mi.

Thanks for the answer.

I think there is room for improvement anyway.


Is there any way to get the usb-tuners working again, without having to reboot ?
( telnet: restart usb-tuners, restart usb-system, etc. etc. ? )
