It really sounds like a Fermax technical job to me, it must be the video switching, if the audio and buzzer to the phones work when the front panel is calling and you can manually select video from the handset then it "has" to be a switching fault.

Fermax tech should be able to tell you how the signal to the phones is handled, I would assume the phone itself uses the same signal as the buzzer and simply turns on it's video display?

You don't say (or I didn't see) if this is a multi door install with a switcher as these can give trouble....

Give Fermax a rocket and get them to help you! B)
