And you started it every time ? Did you wait enough?

I restarted it after every reboot. As mentioned before, I changed both sleep times in the script to 1. I waited much more than one second.

I don't know exactly what happens when the TV "hangs". It stops responding to the remote control and telnet/ssh, but the TV works normally otherwise. When the normal watchdog is enabled, the TV reboots. Maybe the script is unable to detect this state.

Yeah that's probably it For "my" crashes it works

How is the normal watchdog implemented? I suppose it can be found somewhere in the source code. Is the script based on the normal watchdog?

NO

This works in C series? I usually power off my tv with reboot command in one Telnet session. It ever works even if i get segmentation fault. For example when i try patch not designed for C series. Maybe the reboot command works with other series too
