I have a Roland JV-1080 that I bought around 2008 or 2009. I did consider buying a JV-880 which is the module version of the JV-80 but I went for the JV-1080 because it has more sounds and it was used on countless recordings throughout the mid 90s well into the mid 2000s. Part of the reason I prefer modules versions of Roland PCM synthesizers is because of the problems with the glue on the key weights as well as space being a bit of a concern but as always you did a really god job at restoring this one. These Roland JV synthesizers are still usable in modern productions and I don't think they sound outdated at all, you should record some more song covers using the Roland JV-80 in the future.
friend I have a jv 80 similar to that but I still don't know if it's in good condition since I bought it without a power cable and you can't test it... do you know where I can get that cable... to see if it lights up or not and where are you Are you located to take it for maintenance and repair?
Great, looks like new and sounds great. Roland instruments last forever … besides the well known „red glue“ issue… Hm, my Hohner E3 could need a clean of some upper key contacts, too. But I worry about „opening“ the keyboard itself, since it does not lay down flat, but is flapping around in the breeze in some wierd angle. I don‘t know if some parts will fall out.
What a great find! Did you end up removing the red glue? If not it will drip into the PCB below eventual and destroy it. I’ve repaired a few JD-800s which also had this issue.
You should have put all the keys in a bucket with liquid sink unblocker, let it stay for 8-12 hours, wash and dry the keys and the weights and then glue the weights on the keys with 2-component glue. As long as you leave the red glue under the weights, it will be a time bomb again

All keys have to be removed and cleaned with a solution of caustic soda and water. Often the weights keep on their places , so I sealed them with locktite
Greetings organfairy. Thanks for uploading the video. FYI - the capacitor on these expansion cards are notorious for exploding. I've had this happen to me and as a result replaced the caps for all the expansions I own. A link to a video here to explain: ua-cam.com/video/Ficulw9OyxQ/v-deo.html
Just cleaning off the bit of red glue is only going to be a temporary solution. Maybe you are already aware of the "red glue of death" that has plagued many of the Roland synths produced back in the 90's that have weighted keys. The "red glue" is an epoxy Roland used that over time started to soften and leak. Stored incorrectly this glue could damage other key components of the synth but most times it only impacted the keys themselves. I just recently overhauled my JV-1000 and cleaned all the keys and now it plays flawlessly. Take a look at this link here on youtube. ua-cam.com/video/LrKK6sNMLsU/v-deo.html
Unfortunately you are right: They have started falling off my keys. My solution is simple: I just remove them completely when the start falling off as I am not used to weighted keys anyway (I am an organplayer).
@@organfairy Understood. Whatever works for you. The thing you should be aware of is that sometimes the weight don't drop out completely, especially the black keys. Prior to my thorough removal of the glue, I went to play the synth one day and I was unable to depress some keys thinking they were stuck with glue but it turned out that some of the weights came loose but were lodged under the key preventing me from pressing down on the key. Fortunately, I noticed this when I flipped the synth over otherwise I probably would have broken several keys.

Congrats on an incredible score! With the techno card!
The first piece of music reminds me a bit of "The Oh Of Pleasure" by Ray Lynch.
What a nice fix you did here repairing the broken key !
Great music too !
Is the back up battery of the Roland still ok ?
Great music too 👍
Yes, there was 3V on it.

I didn't know about the "red glue issue". Are there any ways to cure it or do I need to clean it all off?
I have a Roland JV80 which has problems ando I want to know if You can help me

I know. But the thing is: I am an organ player, so I prefer keys with a light touch. My plan is simply to remove the weights when they fall out.

We have a Roland Rhodes VK-1000 it has a problem with most of the buttons and they look very similar to these, are they cleanable and or repairable?
They are very hard to clean because the individual switches are a closed plastic construction. It's probably best to replace them.
@@organfairy okay thank you!
Lucky! I would have too

Caustic soda? That seems like a quite drastic solution.
