Hi folks,
I've had this pair of Aerius i's for a few years. A few months ago I noticed that the right speaker would often take several minutes before making any sound -- the woofer and the panel would both be silent and the red LED at the base would be off until it finally came online, and then sounded fine. Over time, I'd notice it would occasionally cut in and out momentarily while playing, sometimes with a bit of static.
For some reason I decided to wash the panel (in retrospect, not sure why I went this route instead of straight to the circuitry). Fortunately I didn't damage anything, but it didn't make a difference. When it makes sound, it sounds fine, but it takes longer to spin up and sometimes cuts in/out.
Yesterday I took off the back panel in hopes I'd see something obviously wrong, but everything looked great. The LED on the board itself does come on. I tried measuring the voltage across the points that bolserst pointed out in another thread, and it looked okay (~260VAC). Note that since I have an MLPS103 board and those instructions were from an MLPS102, I actually measured between the left side of D27 and the right side of D13, but I think that's okay based on how I understood the schematic.
I put the speaker back together and, again, no difference. Took forever to make any sound (at first I thought I broke it), but it eventually lit up. Not sure what to do next. I'd appreciate any help!

Just wanting to confirm, the woofer cuts out too not just the panel? If so, I don't think there is anything wrong with the PCboard.
The LED not coming on and woofer not playing are both indications of audio signal not getting to your speaker.
Have you tried swapping left and right speakers to see if the problem follows the speaker or stays with the amplifier channel?
From your description, it is more likely a problem with amplifier/electronics or cabling between them.
Hah! Well, don't I feel dumb. Just a loose connection on the back of the amp. The curse of being an engineer. Thanks for your help!
