Just got one and I cant get the OS to update.
I know the port is ok, I can recieve midi notes fine. I've been trying to get MIDI-OX to send the update. The MIDI interface is indicating that it's sending but the Virus doesnt react at all.
After days of troubleshooting, I've come to the conclusion that my issue is likely the (well known) electrolytic capacitor burnout. The screen has a very mild backlight flicker when I send the OS. Judging by people who have advanced forms of the disease, if I dont get it fixed, one day soon old red won't even turn on anymore.
Unfortunately, I always used to get stoned before 10th grade electronics lab, and now find circut boards really intimidating. A guy over in Castle Hill is about to feed his wallet off my insecurity.
I know this is an old thread, I was wondering if the guy in castle hill fixed the problem and how much did it cost you?
Interestingly I found out that electrolytic caps can be self healing: Just turning on the unit and leaving it on for a while might actually rejuvenate the capacitors. Try a few times, leaving it "on" for 20 minutes each time. Capacitors are a very common point of failure and a good repair shop should be relatively cheap. One that specializes in music gear or has seen a Virus B before shouldn't end up charging a fortune.
