LIRC is a daemon (/usr/sbin/lircd on my system) and /etc/init.d/lirc is the script to start this daemon.
If I restart LIRC I see the following in syslog (on my systemd system via journalctl -f):

Unfortunately I don't have journalctl, and I didn't afford to install it on Debian Wheezy.


Your line "[FAIL] Starting remote control..." means that LIRC has any problem.
Please try to find any other entries in any logfiles that may be related with this problem.
This failed start should be visible in syslog...

You've right. But curiously, I didnt find error :

grep lirc /var/log/syslog

nothing.

On my system the package from TBS installs in different directories than the original modules are.
This way I had a mixture of original modules and modules from TBS. After deleting the original "media" subdirs and reinstalling TBS stuff all was ok. But if it become necessary to restore the originals you need a backup...
Maybe your system has a different directory structure?

Yes, I think so. I see 2 path :
/lib/modules/3.2.0-4-amd64/kernel/drivers/media/
/lib/modules/3.2.0-4-amd64/kernel/drivers/staging/media/ 

(I am afraid that if I restore media from backup it erase news modules from TBS).Theses points (path and need/or don't need to restore backup) are not very clear for me.

Try this on your system...

Unfortunately I didn't find this file :-(

Your /etc/lirc/hardware.conf could be somewhat that /etc/sysconfig/lirc is on my system.


Yes, that's why I did'nt find /etc/sysconfig.


At this time, I think **the point** is to clarify is the configuration file :
path, name and content.

In case I can't find/fix this, do you think it could be interesting to try with a fresh install of  Debian Jessie **8.4.0** which kernel 3.16 ?

Thanks again for your support.
Best regards.

Karim
