Hi guys!

Please help my TV to prevent a flight out of the window. It tells me "Weak or No Signal" for certain TV stations.

This is how the problem is created:
I'm watching TV via dvb-s. If I do a rescan for a specific transponder (new TV station came out), some channels seize to work. I do not see any connection between those different channels.
If I click on Self Diagnosis --> Signal Information, no frequency is shown. I would have to rescan all those transponders whose channels don't work on my TV. This is really annoying.

Do you have any idea, why my TV does that?

When writing back the channel list I had before everything works fine until I repeat the rescan of the transponder I need to rescan.

Best regards
Matthias

Hi everybody,

I just wanna ask you whether anybody has a clue how to fix this issue above.

best regards

remove "weak signal" popup? You need to do cosmetic "removal" of unwanted popup, right?

Hi,

thx for your reply.

Well, the popup itself does not represent a problem.
For some reason my channel list gets screwed up, since there is no frequency (Self Diagnosis --> Signal Information) for the channels that show the mentioned popup.

Can be you have hardware problems? Eg. tuner capacitors or so. I don`t think this is software related.

Well, to be honest: I don't think that this is a hardware issue. It must be a software issue.
If copying back my original channel list everything is fine.

But for some reason, when scanning for new channels, the channel list is being messed up: It obviously looses the frequency for some channels. Rescanning the affected transponders fixes the problem. BTW the existing and not working channels are not overwritten.
In any case this is really annoying

Okey, (i can`t believe i advice that for you), then maybe firmware downgrade/upgrade? Also reformatting mtd_rwarea could do the trick (via exlink or trough telnet console).

Thx for the hint!

How do I reformat mtd_rwarea via telnet?
What happens to all the original files there when formatting it??

nothing critical should happen

on B series /mtd_rwarea is /dev/stl0/14, but you need to check (mount | grep "mtd_rwarea")
Then
1. unmount 2. format (yes, bml !) 3. format to stl 4. mount (not necessary, but to check) 5. reboot tv, scan for channels.

Hi juuso,

thank you very much for the code!

When trying to execute "partition.erase /dev/bml0/14" it tells me that there was no such file or Directory.

The Folder dev/bm10 exists in any case.
