Alesis Micron Screen flashes on and off then powers down

[xenomorph313]

Hello synth friends. As the forum thread implies, I am having a bit of a dilemma with my Alesis Micron as of late.
I'm using the 1.5 A power adaptor that shipped with it (always worked fine for me), but now for some reason i turn it on, and I'll be playing it...about 10 seconds later I'll hear a ("ZZzzzzzirup") sound then the LCD screen flickers a couple of times, powers off and the unit reboots. It just continues to do this until it becomes so annoying that its unplayable. Any thoughts as to a cause and a solution to this mystery would be greatly appreciated. Its too bad, as the DSP processing on it makes it one of my favorite instruments. Thanks guys!

Hi,
It sounds like a power issue, I would recommend to try another power supply.
Other than that, it could be a problem on the internal psu.
If you are brave and you have a multimeter, you should check for +/- 9V, 5V, 3.3V and 2.5V on the internal PSU.
The schematics can be easily found via a google search.

UPDATE: The Ablegrid 9V Adaptor did not make any difference in the Micron's behavior. It appeared to work fine for a few minutes, and then it started acting up like before. Must be something in the circuitry or a component on the board(fried capacitor maybe?) although I checked every capacitor with a flashlight and there was no charring present on the board anywhere. That being said, the Micron HAS fallen a couple of times (they are just not the right width for keyboard stands). When I run on my treadmill stuff falls. Oh well, maybe its time for a new toy. Peace out.


Yep that's what I'm hoping for. I've got an Ablegrid 9V 1.5 A power supply on order from Amazon which will be arriving this week. I noticed that the current power supply is bent a little bit at the plug and when I straighten it the power flickering issue doesn't occur as frequently or at all. I did the diagnostics test (OCTAVE - ) and (OCTAVE +) buttons held simultaneously while powering on. The "Z" encoder knob flutters between -4 and +12 on its own without touching it but I'm hoping this is linked to the fault in the power supply. We'll wait and see what happens and I will post the results when the new PSU comes. Thanks all!
