TPA3100D2 popping

Hi everybody, new here.

I'm repairing an LCD TV and I found this amp IC in this TV.

If I'm using an RCA cable and plug it in an another amplifier the pop is not heard.

So this is why I'm thinking that the pop it has to come from this IC.

Anybody would know what can cause this pop?

Somebody could help me out with this issue?

I would apreciate it.
