Hi,
yes, both constant 12v and ignition 12v are connected. It didn't work one day in the car where it did work the day before.
After that I tried on the workbench with a 13.8v power supply but it just stays on standby.
It is not only the display which is not turning on, it's the whole radio.
Maybe the current is first supplying the display, via the flex, and than the tuner itself, so it already blocks at the
display not getting power?!
There are no eletrolytics in there, only SMD. It's not a very old radio, it has navi, BT, DVD etc
I just found a brandname, it's a Meos MC701B, year 2008... never heard of it though.
