MOST issue with one module dead?

How i can fing out which module is died?

 

[Botus]

not an expert,

diagnostics but may not behave as module dead,
swap modules out for known working element and see what happens,
or could try and link out elements with a fibre link thingy, but not sure what you could link out, TV or DAB, if you had those sperate modules but I think the rest is part of the system

I have taken off the amplifier and guess what? The fiber cable was loose and come off!!!
All working bow!!
Thank you all for your kind help
