Uno problems SNR after deep standby wakeup

[Mr.who]

Hi Team,
I have vu+ UNO with blackhole 2.0.7, when I wakeup the box from long deep standbay, i have not Signal on all channel (SNR 0% AGC 0%). and sometimes i see the channel frequency ("info serivce") on tuner status is diffrent of multiplexe.
I must reboot the box once or several times to have SNR.
please what is the cause of this incident ? and how resolved?
Thx,

To me, it resembles more of a problem with the antenna installations (LNB/Cable) than image.
Provided that the box is not a defect.

You probably have a picture on one polarization vertical ?? and the other does not.

Voltages.
12.5v to 14.5v gives vertical and 15.5 to 18v gives horizontal polarisation.

If you have a bad connection in the cable
then you'll hardly get horizontal.

Of course this is just my opinion
you have to test .

Thxs Matrix for your replay,
i have not picture on V and H
when i open info serivce to see the frequency channel on tuner status, its different of correct frequency of true channel.
I do search on the net, it's looks to "fixed rare PAT timeout problems after deep standby wakeup"

Anything is possible.

But , I've never had,
in any E2 receiver I nave not noticed something like that.

I use SAT list by @ Likra
Uploaded/FTP with dreamboxedit.

 

[Mr.who]

yes Anything is possible, but i would like know the true cause to resolve the incident.
for list SAT i tried predefined list and i tried manual scan but same incident

 

[Mr.who]

Matrix i find cli command or plugin to debug Tuner status, voltage or tuner activity or tuner log? other than /var/log/messages
its help me during the problem appears

 

[Matrix10]

I do not know anything like that ,

Maybe someone knows.

 

[paolino]

@Mr.who : Do you have Uno with Single tuner or Dual? How old is your box? You wrote "Long deep standby...". How long?
To know these things is important to solve your problems.

 

[Mr.who]

Hi paolino, my uno with single tuner, is moin a year old
"Long deep standby." +- 15 minute

Could be a power supply or tuner module. Try to reflash with original Vu+ image, if the problem persists, ask for warranty repair (two years warranty in UE).

 

[Mr.who]

@paolino another information, after the wake up from deep standby, the pid of startup channel ( PID Video, PID Audio, PID PCR, PID PMT..) are Empty NA..

 

[paolino]

As I told before, power supply or tuner module.
PS: I'm quite sure, that when you leave your box only in Standby (not deep), everything is OK. Could you confirm this?

 

[Mr.who]

Yes i confirm,
for exemple now I wakeup from deep standbay, startup channel is M6HD fréquency 12168 29700 V, but the tuner statut is 10600 29700 V
on the boot the tuner tune false frequency than startup channel

 

[Mr.who]

And now i do reboot the box from the remot, and all is OK
if its a power supply or tuner module, why after simple reboot all is OK?

 

[Mr.who]

@paoulino
I measured the voltage on LNB when i have the incident(after wakeup from deep standby), V and H = 0V
after simple reboot from remote, V=13,8v H=18,8v
why The box or tuner do not supply the LNB after the long deep stanbay?
its sofware bug or hard bug?
the lenth of coaxial cable can be cause?

 

[paolino]

Hardware problems. PSU (Power Supply Unit) is most probable cause of your problems.
Let your box only in standby (not deep) PSU will be still in temperature and capacitors too. I'll give to your PSU about 6 months of life.

 

[Mr.who]

I hope it will not Hardware problems PSU
Teams, Thanks for your support

 

[Mr.who]

@paolino i will done my box to warranty repair.
exactly what equipement is fault? PSU or Tuner device?
The V=13,8v H=18,8v are delivred by capacitors into PSU or capacitors into Tuner Device?
The PSU delivred 12V to HDD and box, USB without problem.
and when I resolve the incident with reboot i have log "dvb_demux_feed_del: feed not in list"
I need your experience.
Thanks,

Yesterday my tuner do no not power the LNB, voltage 0 even after several reboot.
Black Hole 2.0.8.1 its worked for SEVERAL days , but yesterday the SNR flaped and after some time don't have SNR and voltage.
its problem of tuner or PSU, how can I confirm this?
The tension 13V/18V is delivred by PSU or Tuner Device?
The PSU delivred 12V to HDD and box, USB without problem.
I have not another tuner for test.
warranty repair is expired, please help me to identifyi the cause.
I can't buy new tuner if I'm not sure that the tuner is the cause

Of course, not directly from the PSU
It is a signal with DiSEqC commands.
Bit patron at the top of the voltage.
