Hello! I have purchased Mini 0906 pro on AliExpress. All works great, but rear camera doesn't work. It has yellow strips along all video. I tried to reconnect it, change settings, update firmware. Aliexpress can only return me money back if I send all package back. But it's installed already and power cable is deep inside my car. It works and I don't want to change it. I need to do something with back camera only. Please advice!
