Roland JV-880 No Audio

Hello,
New to me Roland JV-880, no audio from main outputs or headphones, factory reset > passes all tests except no audio output. Tested outputs on multiple input sources. Rare both main and headphone having issue same time, isn't it?

Any ideas, advice?

Noticed a couple of other threads online explaning same situation but are one posters with no reply to those offering support.

Thank You

Will try. Sent message to seller asking how they tested. It feels like I am missing something since all outputs are not responding. The Synth looks great too.

Will report back.

Thanks

MIDI problem? Does the MIDI LED above the power button flash?

Do the factory demos play?

Quote:
• Playing the ROM demos

There are 3 ROM demos in the JV-880. To access them:

1) Press UTILITY.
2) Rotate the DATA dial to ROM Play.
3) CURSOR to the bottom line of the display.
4) Rotate the DATA dial to select the desired song.
5) Press UTILITY to exit.

Could be as simple as having the MIDI channel wrong. Did you check that? Does the MIDI LED light when you send it notes?

As rockmanrock said, try the factory demos. If those play, it's probably a midi setup issue. Also, pushing the volume knob should preview the current patch.

The midi light does come on. Tried the volume knob also to preview programs and demo.

Here is a video I just uploaded. Still working on it.

Got some audio signal out of the Roland JV-880 but it isn't pretty.

returning it. did seller test before despatch? where did you get it?

I had a similar experience with no right side output from phones or main outs, ended up being a ribbon cable was all. May have became loose in transit.

Return process initiated. Change of midi setting seemed to increase issues.

The unit looks beautiful. Sent message to seller 3 times since yesterday with no reply. Wild guess that they did a screen test and not audio.

There is no education in this thread. Remove if needed.

Thanks

The ribbon on the middle of the board is connected well. With battery out had ram error. Battery back in, no error and same issue. Reset, same issue.

Will mail back tomorrow. Will try any other ideas until shipped and cancel return.

ship it out and get a cheap JV1080.
easier format, easier to program.

or get an e-mu.

Plan was 4 synths.

JV-880

Anyone agree or disagree with this statement.

" it depends if you want to own a true 'classic' digital synthesizer or are just fishing for a ROMpler with biggest ROM-for-the-buck. If former is the case get JD990, if latter - save up for used XV3080 or 5050, or better yet Fantom XR, and jump over JV1080/2080 line alltogether." -clusterchord 2001

The JV-880 made the list because it is just really cheap.

Really wished the 2080 sounded like the 1080, like the features more. Other than quality, do you think the 1080 could cover the sounds the 880 can and more.

Do like what I see and hear about the 1080. Will look into the, "jump over" statement made in 2001.

Still replacing battery. It seems dead now on the 880.

Thanks

i'd be surprised if the battery's the problem. some way of checking the
jack connections?

i had a JV-880 long ago. quite liked the filtering. but i let it go, had a much
easier e-mu with its filters; not quite as clear, but wdf...

20 yrs later, a mate locally say here got this, do you want it, 100eu.
jv1080. yeah sure, why not. 2U, shorter chassis, much easier programming,
and as far as i'm concerned, the same sort of thing, with better fx.

but by no means essential. looks da bomb, that LCD, lovely unit.
nice-ish sound. pretty horrible to program really, with not enough user
patches (same as 880). i don't really like that roland design ethos at that
point - but i know my way round it, and it can do some nice stuff. not going
to lose sleep over it though. i would rather have that than the 880. the fx
can help spatialise it better. needs more user patch memory.
i do not know if the 880 has a more robust sound; not really that bothered.

Battery did not help. Thanks for 1080 advice. Never looked into before.

The connector you'd want to check is the one on the left side of the board that connects to the volume control and headphone jack. There's a connector on volume control side too. Reseat both of them.

I'd go for either a JV1080 or XV5080. The XV3080 is more or less a rehash of the JV2080. The JV880 has some different qualities that make it noticeably different from the others, but I'd skip it if you're not looking for that sound specifically.

Hello,
Forgot to attach a rack ear when packing for return. Could not resist taking it apart. Removed screen to get to headphone housing. Checked all connections seemed fine. Put a bit of pressure on the wires. Straitened bent capacitors, some were leaning, some were bent and making contact with neighbors. Put back together.
Went to different power source other than power conditioner. After the mute period was over... "I have sound!"

Then I racked it and same problem. The slightest pressure on the top of the case near the expansion access shorts it. Out.
Going to give it it's proper space she needs and keep it. Thank you for all Suggestions. Helped me stay motivated.

Will keep an eye on that ribbon and pressure from above. Let me know if there is really good deal on expansions.

Audios.

Cool story bro...

I would also look at the JV-1010. They can be found for around $100. It has all the sounds from the 1080 and 2080 in half rack form

you might have a cracked solder joint somewhere on the audio ribbon connector
or just the ribbon itself might need replacing.
all depends where that pressure is affecting the case and pcb.

i have a Kawai K1rII with multiple outs in beautiful condition that has just never
played back the waveforms correctly. have no idea what's going on with it.

Been a while.

Inspected the JV-880 again and yes, tapping on the top cuts noise off and on. Found that just the lightest tap on the psu bracket, which is secured just under the cover, cuts the sound in and out, pop, crackle pop pop.

The tapping is so light. More like; touching and https://youtu.be/8GymGszRFN8

The only thing I can think of is shorting out.

Anyone want to give me advice on swapping out the 2 prong cable for three?

Thanks, Happy Halloween!
