TVIP 412 Problems with old TVs (HDMI)

[Beny]

Hi

The 412 Devices sometimes have problems with old TVs.
The 412 starts, but no signal on HDMI. Testet with diferent TVs and different 412.
If i use the 412 on a new TV, there is no problem.

So what can i do? Do HDMI Auto-Bildrate helps if its "on"

Do you see at least bootlogo on the screen?
Can you provide some example TV model that does not work?
