One of my Mojos has gone bad, can't get reply from Chord Customer service.
All three of my Mojos ran cool and played flawlessly. I replaced thousands of pounds worth of DACs with Mojos. Recently one of them would not stay on whilst charging and not playing. After a day I would find it with the white flashing light and completely flat, so the charger was timing out. I have tried 3 different chargers (Anker high power 10W per channel and even my iPad Pro 14W charger). If I get it back on by unplugging it and waiting then replugging the USB charging cable in it will start to charge up. I can get it fully charged but it will self discharge overnight whilst switched off. When playing it gets much hotter than the others. I have changed the cables, lengths of cables but everything works with two, nothing with the rogue. I contacted customer support some two or three weeks ago but had no response. Is there an easier way to get this RMAed.
This doesn't help you, but I've had something similar happen with my Mojo.
The first sign that something was up was when it got unusually hot (charging temperature hot) whilst playing (and not simultaneously charging). I noticed at the time that the battery light was solid white, as if it was charging.
Subsequent attempts to charge the Mojo were hit/miss, always using known good chargers and cables that had worked in the past (an HTC phone charger and an official Apple charger). Over the course of three successive overnight charges from red/amber, the next morning the battery light would be green (at best), amber or flashing white (the long charge time warning). The unplugging/replugging the charging cable trick worked for me as well, but I still couldn't get it back to blue.
Mine went back to Chord (I hope!) via my dealer about three weeks ago; haven't heard anything back from my dealer yet.
Out of interest, when did you purchase your faulty Mojo? I bought mine last November.
