• Roland Juno-G LCD failure and replacement

    From Nightfox@VERT/DIGDIST to All on Mon May 9 10:51:24 2022
    I have a Roland Juno-G synthesizer, which I've had for a number of yaers now. I like playing music with it every so often, but in the last few months, I've noticed its LCD display seems to be starting to fail. I've heard LCD failure is a common problem with this model synthesizer. I turned on my Juno-G a few months ago and the LCD was pretty much blank; I tried it again a copule weeks later and it was fine, so it seems it might be an intermittent issue for now (though I suspect its LCD will probably fully fail at some point).ããI've contacted a couple of repair shops, including an authorized Roland repair shop in my area, who have said replacements are hard to come by (as it's an old synthesizer now), and it seems there may be little chance of being able to get it repaired.ããThe LCD is an important component on this synthesizer, since it provides information on what sound you're playing, what mode you're in, etc.. It seems my best option might be to buy a new synthesizer. :/ I also have one of Roland's SRX-07 sound expansion boards in it, so I'd hope to find something with a similar sound set and capabilities.ããI'm curious if anyone has experience with Roland synths? I've heard the Roland Juno DS has similar sounds, and Roland now offers SRX sound downloads from their web site. Also it looks like the Juno DS is at about the same price point as the Juno-G was, so perhaps it's aimed at the same target market.ããNightfoxãã---ã þ Synchronet þ Digital Distortion: digitaldistortionbbs.comã

I had turned my synthesizer on once and the LCD wasn't showing anything, but a couple weeks later I turned it on and the LCD was working fine. That made me wonder if there may be an intermittent connection failure or something, rather than the LCD itself failing. But then, I suppose the connection failure could be in the LCD and replacing the LCD could fix it.ããEven if there are a bunch of those LCDs stored in a warehouse somewhere, they seem hard to find online to buy..ããNightfoxãã---ã þ Synchronet þ Digital Distortion: digitaldistortionbbs.comã

I bought mine used in 2011, but I think they started making this model around 2006-2008. I seem to remember hearing stories of particularly bad capacitors around that time.ããNightfoxãã---ã þ Synchronet þ Digital Distortion: digitaldistortionbbs.comã

If it really is pretty much impossible to fix, I've considered buying a newer Roland, perhaps a Juno DS. Maybe I can find a deal on a used one.ããNightfoxãã---ã þ Synchronet þ Digital Distortion: digitaldistortionbbs.comã

The little smt cans with not bulge, but they will leak a fidhyãsmelling compund which would eat away at traces and pins. Use a littleãvinegar to neutralize it ebfore re-soldering the cans.ãã---ã þ Synchronet þ The Cave BBS - Since 1992 - cavebbs.homeip.netã
