Hello,
I Have a problem about my multimedia radio in my car,
According to the motherboard scheme,
I replaced two corrupted components:
1) Q26 - to enable to "Acc +3V3" to work
2) D6 - to enable to POWER_+B to to turn on the chip
Currently I'm blocking on understanding why the MCU doesn't turn up to "1" of "POWER_ON_CTL" pin,
In Addition I did some test check and tried to do it manually by connect to ground of emmiter of Q4,
This test enabled the "POWER 12V" and more
Anyone can help please ?
Thanks,
