Hello. I have a 2011 Prius 3, with 500.000km. My Display don't work. When i press the ignition button, the Dashboard display is dark and no beep sound appears. (lights on, doors open). My 12V Battery is new. When its over 20°C, the display works, on cold days, it is completely dark. Sometimes, when i have drive over 50km and the car is warm, the display start up and the Prius logo appears. What i have checked: -12V Battery -solder joints on the display -everything re-soldered -Pin 1 and 3 on the big connector have 12V (have someone a current circuit plan?) -the capacitors dont have voltage applied -I have a Laboratory power supply. I put on pin 1 and 3 voltage, but nothing happened Can someone help me?
Any moisture ever get in there? All connections are tight? The dimmer is not all the way down? Any codes that could be read?
