Hello everybody,
The above subject amplifier is going into cycle between on and protect. This one has micro controller i tried to ground IN1 to ground and the amplifier came on. Before this I have tested all the components for any shorts but I did not get any. After forcing it to come on the amplifier plays good with good sine wave on outputs. The IN1 pin is having 1.5v when it goes into protect. Any help is highly appreciated. I am attaching the images.

All the components in that area are very good. The problem was one of the vias in that area was rotten. After testing components i tried testing connections and that is how I found this. Thank you once again for your help which made me think that something should be only wrong in that area.
