HI!
This 4 channel 2din radio has one of the outputs driving a cc voltage of 12v into the speaker coil burning it.
Replaced the Y7388 AMP IC and the same is happening.
I noted the 47k resistor when onboard has only 42k and a voltage appears higher than in the other channels.
My doubt is about the IC(U7) ZL3560 that looks it's driving the inputs of the amp, am i correct?
It's my first time with a problem like this and hope someone can give some help.
Regards
