Martin Logan ESL X three strips don’t emit sound at all

[proaudit]

Hello,
I’m experiencing an issue with my 2022 Martin Logan ESL X speakers.
One of the speakers has started sounding more muffled, with weaker high frequencies. I ran the sound testing mode on the speakers and found that the lower part of the electrostatic panel in one of them isn’t emitting sound. By listening closely, I noticed that three or four of the lower strips on the panel aren’t working.
Over a day ago I powered off the speakers.
First, I vacuumed them and then moved the panel to the second speaker.
Nothing changed—three strips don’t emit sound at all. I marked them with my fingers in the photo.
Three of us listened and all confirmed that these exact three strips aren’t working.

What should I do in this situation? Thanks
