In fact if you made the Box wiring -> HDMI Cable> Case Ligawo -> SCART -> Tele
If you turn on the TV box then you have nothing in the end on your TV.
We must therefore disconnect the HDMI cable box ligawo
Turn on your TV, put it on the SCART channel
Turn your box until you see orange box on TV
Then you can connect the HDMI cable to the box and you have the ligawo Orange TV on your TV.
The reverse manipulation is done to stop.
The least: It lacks a off button on this box.
The product meets my expectations even though I am obliged to manipulation for it to work.
