no signal

Post by anto@ »

good morning
for some weeks now I have been having problems with alt dvb
I only see 2 vertical and horizontal polarities low, the two polarities in the high band are not seen
using other players everything works regularly, possible causes of this block
thank you

I should have solved the problem

Please provide details about your configuration.

What DVB card model are you using?
Which module you are using - original dev_BdaDriver or dev_Bda2Driver from crazycat?
Do you have a motorized setup or using DiSEqC switch (eg. monoblock LNB)?

Thanks for the reply
the card I am using is the tbs 6925, in the photo you can see the files in the device folder
the problem that sometimes works well sometimes NO
today it works well, tomorrow I don't know
it happens sometimes while I'm watching a feed that the image freezes, with full screen, when I return to normal view the signal bar is empty, and the image screen turns white, if I turn off the program and I restart it everything works

window 10

For an issue with no signal - wait when this will happen again. When this will happen - if you are using original Dev_BdaDriver like on photo, please check file Dev_BdaDriver.cfg, open in Notepad. You will find there TbsFix22KHz option, if it is set to 1 - switch to 0 or if it is now set to 0 - switch to 1, save file and try.

Not sure if this will help, if not - set this option back as it was originally.

Are you using DiSEqC switch or motorized dish?

For second issue - empty signal bar = card has lost the lock, white screen is only because no incoming stream is present from card, so AltDVB has nothing to show. Why signal disappears? I don't know, you will have to check all possible reasons one by one.

When signal will disappear - are you doing something on PC, maybe some other app is interrputing stream?

For example you can try to try other DVB app for longer time to check if this will happen also on other DVB player - if yes, it will be not AltDVB issue.

Also as an alternative, to check if signal will be disappearing too, you can try to use Bda2Driver from crazycat: https://github.com/crazycat69/AltBDA2/r ... .2.3.3.zip

Maybe you are facing issues with 6925 electronics - some users had issues with 6925, where 6925 gradually lost an ability to lock some DVB-S2 8PSK signals, sample discussions:

https://www.tbsdtv.com/forum/viewtopic.php?f=25&t=9775

If this will happen, it is an hardware issue of 6925 card and cannot be fixed. So hopefully it's not this reason ;)

thanks for the information, the problem is with the driver, I have installed these and now it seems that everything works, if at startup I use the other driver the problem returns if I use the other one, also with the driver I had problems sometimes the signal disappears, I discovered why the signal disappears, on my system I use a diseqc switch, 2 lnb ku, 2 lnb C band, when the signal disappears I saw that the switching for the C band is activated by itself, therefore the channel that I'm looking at disappears, now I'm using the driver version 2.0.3.17 and it seems that everything works, hopefully it will work for a long time

thank you
