Agree that the system is very finicky. It's annoying for us because we have almost zero control over it.

The reset you talk about isn't really a reset and it isn't an approved procedure (read: it doesn't really work). All we can do is put the system to sleep then wake it up again but it isn't a reboot. The cockpit can turn the system off via a switch but I'm not positive if this is a hard reboot. They could also cycle the breaker but that's never an approved procedure to 'fix' the entertainment system.

Maybe tv_man can chime in with some suggestions, and advise on what the three different 'reset' methods really do (sleep button at FA control panel, IFE button in 'pit and circuit breaker) and if they work to fix any problems experienced in flight or at the gate.

It's frustrating or us too because the only official solution is to apologize and tell the PAX to request a refund.
