W211 TV TUNER NEED HELP
I just install tv tuner.

Now i have problem.
No picture on comand display only sound from tv channel 
I checked AUX in tv tuner and its working fine. I change 2 antenna amplifiers with tv support.

Also i found that on RIGHT amplifier have only 2 wires but also have space for one. Also on rear window i found place were it's wire can be soldered
Maybe this is problem ?

Thanks to ALL
