So I have this tiny PG SD500.4 it's a relatively new class D amp with power issues.

When I try power it up the blue board led lights up as does the blue power led, then after a couple of seconds the amp begins to power off then on again, the cycle continues and as long as power and remote are applied.

I think the protection circuit is kicking in, the output and power supply transistors all appear ok with similar readings throughout.

Any thoughts on this one?
