Long time no post...I still have my 2480 and still use it as a demo machine..anyway after years it has developed the cracking problem. On mine it is digital crackling and popping on the outputs..if I leave it on for 10 minutes it goes away. I am an electronics engineer, and based on experience, my gut says this is a capacitor failing somewhere...and it seems to be an issue as these machines really age now, based on looking around and seeing quite a few others reporting similar issues. I've never worked on a VS2480 before...but I'm going to have a go at fixing it at some point and will report back....if anyone finds anything out before me, please report here! I think this is an issue that is going to affect many if not all VS's over time..so it needs proper diagnosis.

Ok, I did some further tests on the VS2480. Mine is running OS version 2.504

I finally found out how to get to the test mode diagnostic screen (Press and hold Page + F1 buttons while powering up). I then ran the DSP Check and the results were not good. I got a code 111 on not just one, but ALL of them!!!! While I was at it, I also noticed the internal battery is NG (no good) and needs to be replaced. It is apparently a CR2032 battery and it is located just under one of the effects card slots on the main board. My fader #4 motor appears to be bad as well because it failed the fader test.

I was really hoping this crackling issue isn't a major hardware problem, but it very well could be from the looks of things. If so, that's a real bummer because this machine sounded so good when it was working properly, especially when I add effects from my three VS8F-2 cards. The sound I get from this unit as well as those cards definitely make it worth fixing (well, maybe). Question is, could the failing DSP chips be the culprit causing the crackling noise? And does that also mean my main board is shot and I need to get it replaced?

Than again, even if the main board is the problem and I get it replaced, there's no guarantee the replacement main board won't eventually fail at some point as well. On top of that, there are only so many VS2480 spare parts available and their supply will eventually become depleted. Is there a permanent fix to this problem or are these units all pretty-much reaching the end of the useful life?

my vs2480cd is now around 18 years old and has developed the no audio symptom when booted up it take 2 to 3 reboots for the audio to appear aso i have the crackling problem when its booted up this goes away once i have let the machine warm up and run it for around 1 hour do you think there is a finite life on these machines i have a spare HHD version which i use for live recording at gigs and no probs at all with it and its an older machine

Yes.

I have the crackling problem. Did you get to the bottom of it?

I was wondering if anyone got around to replacing capacitors during the quarantine over the last couple months? If so, did it address the crackling?

How about Roland support, did they offer any insight?

This seems to be a topic often asked about, but rarely reported back on. Did everyone else who experienced this issue simply abandon their machines and switch to a DAW (or some other Platform)? Surely, at least one person solved this mystery, lol....

I, too, have that same slight static in playback when the machine is cold. This has gotten progressively worse. Currently, the static remains for 30-40 mins and I often have to reload projects to get audio playback when the machine is cold. Once warmed up, the machine functions well, though with slight occasional crackling. I exported the tracks and the tracks are completely clean, the static is only on playback. No hard drive problems, battery is new, no effects on the tracks, and no digital equipment connected that might cause a clocking issue.
