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.

    Hi, Tibor,

    Most likely, the cause of the pop is mismatched inputs on the inputs of our amplifier.

    Hi Don,

     

    Thank you for the fast response, but I'm not an expert and I don't really understand what that means? Some input capacitor can be bad?

    Hi, Tibor,

    Sorry, I lost track of this thread. Did you get your TV fixed?

    I have just purchased some 2.1 PC speaker system and using the audio out jack and disabled the speaker from the menu. The TV it's sold.
