I have two units synced via midi cables and coaxial in and out.
I can see meter movement of tracks recorded on unit #2, but I see no meter movement of tracks recorded on unit #1. I also hear no output. I have the monitor outs (7 & 8) routed to a Mackie Big Knob's DAW Mix yet I see no meter signal on the Big Knob's input meter. This setup has worked before many times. It's been a while since I fired this up. I also notice both units show that the batteries need replacement. Is this the cause?

Any help will be appreciated, thanks.

Unlikely, but change the batteries anyway.

Lack of meter deflection/track playback can be a classic symptom of capacitor failure.

Crackling during playback can be an early warning of cap failure If youíre handy with a solder iron, you can do the recap yourself.

Thanks dkfackler,

I was able to get playback after doing a re-load of the current project. But yes, I have crackling during playback, so I believe I have the cap issue.

I don't think I could do the recap myself. I have other 2480's, so at this point, I'll likely use the best one.

I have three -3 cards in a unit with crackle, I'll likely move them to the best machine I have.

As you have two VS linked, check that "COAXIAL IN" is on in VS #1 ( Master VS )
under "UTILITY" --> "PROJECT PARAMETER".

If not "on" there will be "snap, crackle and pop" when you play or record ....

If you un-link your VS's and play them one by one and still have crackles,
then there's probably the capacitors


Cheers !

I went through all the internal settings (like coaxial in), several times, to make sure I had it correct.

Needing to reload a song to get playback can be symptomatic of failing caps as well. That was the case with one of mine. Recap fixed all.

Yes. Itís not difficult. IIRC, there are 48 100uf6v electrolytics to replace. I used 100uf16v radial lead caps; cutting the leads and bending to 90-deg to solder onto the original PCB pads. Do one at a time and go slowly. It took a couple hours. The main board does not have to come out. I had a list of which caps(by number) on the main board to replace. Itís in the 2480 Service Notes.

Does that mean there's other caps on the main board that don't need to be replaced ??
Or is 48 the total number of caps ?
( Asking for a friend )

Cheers !

IIRC, there are a few others(three 220uf, maybe others), but I replaced only the 100uf6v values, based on the experiences of other Planeteers.

A Tip: you will see a cap removal process in which pliers are used to twist the old caps from their solder pads. I donít recommend this as the PCB pads are fragile. Unsoldering, although much slower, is safer.

GEEZUS H. K.REIST!!!

I absolutely agree 1000%. ESPECIALLY being subjected to 20 (or so) years of use.

You might cough on these PCB's and risk snapping them accidentally.

Ok, THAT's actually a bit of an extreme statement; but you get my drift, correct???

I'm having the same problem but I'm not too sure if I myself would try to do this replacement. I may turn my 2480 into a paperweight, is there anyone that you may recommend to do the work? I'm willing to pay for the service. Thanks.

I imagine a local electronics repair shop could do this.

PM if you like the list of caps to swap. Each one has a unique number on the board.

Daniel, How did you unsolder the original caps? I can't find a way to do both sides at the same time. Did yo use solder braid?

Grip cap in long-nose pliers. Heat one terminal while gently tilting the cap away from the terminal youíre heating. When that joint comes free, repeat process on the other joint. You can clean the pads with solder braid, and use flux when soldering the new caps. Note the polarity.

I'm not able to DIY stuff myself, (bad eyes, fat, stumpy fingers), but I have the Roland VS-2480 Service Notes (first edition) (roland_vs-2480_[ET]) in pdf if it would come in handy for anybody.

Thanks Daniel. I have a spare non functioning Mother board that I'm going to use as polarity reference right beside me. Caps will be here Wednesday from Mouser. Did you set the caps flat or did you leave a little gap under them?

I used radial caps and bent the leads 90deg to make ďfeetĒ which were then soldered to the pads.

Yes, I went with radial also. How did you deal with the caps that sit under the effects cards? Very limited space.

I think there's some really bad advise being given in this thread and if you're thinking of doing a recap yourself, DON"T! I ordered both radial and SMD caps thinking I might be able to do it either way. Luckily I started by practicing on a salvaged MotherBoard I had. I tried de-soldering and the first six caps each also removed the copper pad. So I thought maybe too hot on the iron so I turned it down. Same thing. Next I took long nose pliers and tried the twist off method as demonstrated on You Tube. It worked for the first six caps but pulled a pad on the seventh. Now I'm afraid to even think about working on the original board and I'm sitting here with $60 of unusable new caps and a machine that's destined to be a doorstop.

I did recommend unsoldering rather than the twist-off method.

Sorry about your unfortunate experience.

Read my post. Unsoldering was the first thing I tried on six caps. Took a pad off of every one of them. I'm not unexperienced at soldering. I completely recapped a Marantz 2325 (All 13 boards) in 2017. Obviouly SMD caps are not the same technique and are much more fragile.
