Loudspeaker Antenna low volume

Hello,

I had a problem with Xperia D6633 loudspeaker. So I disassembled the phone and tested the speaker.

The speaker sound and level is fine, but as soon as I place the small plastic antenna part (the one that clips over the loudspeaker) the sound becomes very low.

Has anyone experienced that problem, and if so how did you solve it?

Thanks

Thank you for the reply.

The phone is already opened. And yes I checked the grill and cleaned it with a brush with alcohol. There something pressing on the speaker and muting the sound when fully assembled, but I can't find which part is pressing on the speaker.

Have you checked the speaker filters? I'm not exactly sure where they are located but I would assume at the bottom of the screen as you can see the grill from there. I would try 99% isopropyl alcohol brushing on the bottom filter without opening the phone up.
