Hello dear Phaeton municipality… I used the good weather today to connect my DVD player (headrest monitors) to the TV tuner. So in the headrests are monitors with intriguing DVD player and USB etc. Now I installed the Dietz 1230 and installed all kinds of cables. Unfortunately only AV1 is occupied with me on the TV tuner and then only a flickering picture arrives. The sound is great. But picture in black white and bad. Is there a setting in the menu where I use the n Change image mode or something? Greetings Stefan
