Can I repair this Alesis Micron synthesizer? (Part 2)
video upload by Floyd Steinberg
"Two weeks ago, I posted a video showing my thought process on finding the flaw in a used Alesis #Micron #synthesizer and an attempt at starting a #electronicsrepair. Here's a follow up and a conclusion to that story. No table of contents this time, you well need to watch the whole thing or not at all. ;-) There's a conclusion at 08:54, though, if you're in a hurry."

"The hard case is a heavy duty Calzone case. The foam on the back and one side has been removed, but the CZ still fits snug and leaves a little room for cables and whatnot."

"Cosmetically it's in excellent shape, just some scratches and dings here and there but nothing major. I believe it's missing a little bit of wood trim looking at other pictures. Powers on just fine, all of the membrane inputs seem to work but...
The battery inside has died and needs to be replaced but my technician is booked out months. I have the battery on hand you just need to solder it in a very simple job if you have a soldering iron. This is also preventing the patches from being loaded which I can supply as a wave file if you don't have a back up of your own."
