My Midihub has started to have intermittent issues powering on. Sometimes when I turn it on using the on/off switch nothing happens for a few seconds, then the LEDs run through the startup display after which the unit powers on and works normally. Sometimes it can take as long as 10 seconds to come to life, and sometimes it does not power on at all until I’ve turned the switch off and back on again. I’ve changed the USB cable which provides power and tried plugging into different USB ports on different computers, but the issue persists. The firmware is v1.15 and I purchased my Midihub directly from Blokas.
Perhaps it’s just the switch. Can you squirt some rubbing alcohol in there (without usb power) and flick the switch several times. Or real contact spray or WD40? You might need to open it up to get good acces, HTH.
Indeed, the problem is probably the power switch. We’ve heard some compressed air blown into it could help as well.
However, if nothing does help, you may send the unit back to us so we can replace the switch for you, or you may arrange the repairs to be carried out locally.
Thanks guys. A combination of compressed air and WD40 seems to have helped - at least it seems ok for now, anyway. If it helps anyone, I opened up the case before doing anything and had a close look. I know that doing this invalidates the warranty, but I bought the unit a few years ago and any warranty had long since expired. Also, I’d previously thought the screws holding the case together were proprietary ones, but on closer inspection (eyesight not what it once was) discovered that they’re just Allen screws, so was able to open the case. There was nothing obviously wrong that I could see, so I blew compressed air at the switch with it in both positions, then sprayed a tiny amount of WD40 onto a cotton bud, and after applying it moved the switch repeatedly between the on and off positions. Cleaned everything up, put the case back together, and as I say, it’s now responding instantly when I turn it on.
I would not recommend WD40 for contact cleaner. Compressed air or maybe isopropyl alcohol. I would start with just plain compressed air. You can search for “electronics contact cleaner” for other ideas, but anything that is oil based such as WD40 would not be recommended for electronic contacts.
