Help, I can't export channel list to usb. (A series)

Post by kikoseis »

I have a tv le46a956.
I've never managed to export the channel list. I tried with (vol-) + (10 seconds pressing enter). I never get anything. I enter to service menu and I've reset the TV. I have re-tune again.
It does not work.

I install pached firmware from : http://developbyte.com/samsung-tv-firmware/


I tried with (vol-) + (10 seconds pressing enter) again.
I do not see the export window.
nothing happens.

I'm a bit desperate.

Would be nice if we could get to export the list.

The management of channel list in our samsung TV is very bad.

I have 90 radio and TV channels and sort them whenever retunes is hell.

Can you help me?

Thanks

Thanks naabo. I've already checked that, at the time, but does not work.
The problem is that the series A are not equal to the series B.
Does anyone have new solutions?

I also have a LE46A956 and I don't like manual sorting of channels as well.
Binary format of digital channels storage is somewhat different than in B series.
And despite I analyzed parts of television firmware I believe there is no channel export/import function.

Year ago I wrote a little testing program: converter from binary storage of DTV channels to text file and back.
It can export digi channels from /mtd_chmap/map-2
Problem is how to import changed channel list back to TV. exeDSP application keeps in memory
copy of the list and reverts any changes to file at TV shutdown.

Finaly I decided that manual sorting of channels is boring but much faster than making an application
for importing channel list. If somebody willing to continue...

Hi tom.
Can you upload here, in this thread, your files (sources and binaries)?

(for people, who come here can see them, and provide ideas)

Let's see if we are lucky and between all get some way to fix this.

Grab channelmap.c from https://217-115-245-101.adsl.avonet.cz/samygo/
channelmap.sh4 is compiled for sh4-linux. Use gcc to compile PC version.
Take it as abandonware, I'm not going to support it.
And if you develop something usable from the source, please place it to samygo svn.

Mmm...
Can you list the running processes ("ps" command on linux)?

probably be able to load the channel list file in memory by
by an appropriate process restart.


# kill -1 pid. (Restart process)

# kill -9 pid . kill process
( pid = process id)


or other way that could be investigated is:

/etc/init.d/<daemon_name> stop
/etc/init.d/<daemon_name> start
