I was listening to music on my stereo and suddenly all sound died. It still works with headphones, but speakers remain silent.
I found datasheed:

and discovered that most voltages near power stage on page 69 are incorrect and 17V supply is actually at 19V. Should I replace both AN7591 parts? I also wrote down some other suspicious measures from this page - pic related. Please help me, I have no idea how these things work.
