Aeon i panel problem

[jyrisoo]

after moving one speakers panel is not working (blue led is off too), but bass speaker is ok. My shop is one summer break (to check reparation etc), but I would to know if there any chance to fix it? Thank you

This may seem obvious, but have you checked that the power cord is plugged in correctly to the speaker and that there is power to it? If that doesn't fix it, then you may want to call Martin Logan, as they have great customer service.

Double check the connector between the panel and the cabinet. The connection may have loosened up during your move. I know this type of problem has been reported a couple of times in the past with other ML models.

As the cone and basses are ok, the problem is panel related. I would appreciate some instructions how to do the connector control. I read couple of threads of changing of panels, but found no details about connector check.

Hola...the blue cable is soldered direct to the front panel, the black is soldered at the back panel and the red is at the aluminum foil right in the center, bended to the diaphragm. A bad solder joint could be your problem too. Check all solder joints...if you have one loose, you will need an aid of an 80 watt soldering pencil Happy listening,
Roberto.

ok, first steps - i opened the case behind and after removing all the white staff all wires looked ok and well connected. Those 3 wires (red, blue and black) are going first to small black box, which in turn opens from other side - eg directly behind of the panel, where it is actually very tricky to open. I am proceeding with small mirror, but feeling not sure. Any other steps?

this gave no result, will have to wait end of the holiday season and get a shops evaluation for reparation. But does smbd no how much the new panel could cost?

Hola...first of all, there is a High Voltage present there...be careful!!! The three cables of the panel go to the High voltage power supply. I think you have the problem here. You need the aid of a high voltage probe. If you do not have this tool, you must take it to a high qualified tech. or talk to the service department at ML. They will guide you to trouble shoot you problem easy.
