Is there a schematic reasonably close to this amp. It is in protect mode and finding it tough to figure out.

This supply has multiple problems. The 5v supply (pin 14) isn't at 5v. It could be that pin 14 is being dragged down or the 5v regulator in the IC has failed.
If you pull pin 14 from the circuit to check voltage on it, you have to also pull pin 13 and connect them together before you apply power.

I goes to a transistor. Most of the transistors don't measure correctly in circuit or out. I thought the datasheet says something about a biasing resistor built in, not sure if that is causing the messed up readings.
I will look into that part of it right away. I was just going to bypass the circuit and apply +12 to pin 12.
