    Sounds like bad or leaky capacitors. When the caps on the power board on my 42" tv failed, the TV would take time to power up, and the colder it was, the longer it took. I had a large Zenith console TV doing the same thing.

    Interesting.. Maybe I'll open it up and look for any capacitors that look bad. 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.

    There's probably several thousand of those LCD panels sitting new in box stuffed in the back of some warehouse in Taiwan or Japan. The other day I

    My brother and I are both synthheads. I don't have a Juno-G, but he does, and I asked him last night about his. Apparently the LCD issues with those units stem from a factory defect with the original LCDs used, which was addressed by Roland later by offering free repairs. The updated LCDs were available for a while, but stocks have long been depleted. He told me that his was still original, and he managed to make the LCD work "well enough" to be usable, but I don't know the details.

    It's unfortunate, because other than the LCD in mine, mine still seems to be working okay otherwise. 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.

    If you see any bulged or leaking, replace it's brothers and sisters of the
    same type. The little smt cans with not bulge, but they will leak a fidhy smelling compund which would eat away at traces and pins. Use a little
    vinegar to neutralize it ebfore re-soldering the cans.

    I don't have any experience with newer Roland synths, except for my JD-Xi (which is a tiny powerhouse!). I do have an old Alpha Juno 1, though. Clunky interface, but nice sounds. A few years ago, I started looking at the Behringer DeepMind 12 as a way to get vintage Juno 60 sounds without the hassle (and expense!) of an aging 80s synth, but even though it begin as a Juno 60 clone, during the design process it evolved into so much more. I had one in my studio within a month. I'm a fan.

    Have ye any other synths? I'd like to hear about others' collections!

    The only other is a Zynthian (open-source kit-based synthesizer that runs on a Raspberry Pi) that I just recently got (the Zynthian kit just arrived this past Monday):

    Oh, and I also bought a used Roland MT-32 (version 2) from eBay a couple years ago.

    Whenever I think of old synths, I don't think of DX7's or Rolands. I thnk of those cheesy little Casio portables. Here's an example https://www.youtube.com/watch?v=DM-v3cvX8M4

    I looked that up, and it looks pretty neat. I might have to scavenge one of my Pis from its current home and try it out. The Oberheim OB-X emulation sounds quite enticing.

    I used to have something similar when I was a kid. It might have even been a Casio :)

    2002-2003 was the prime plague years, but some companies kept using whatever stock they had left for the next 3 or 4 years.

    yeah that's money. they wont dump their stock and rebuy anything unless they absolutely have to. and at my old employer the workers were real shady. when making repairs they would scavenge in the recycling area instead of pulling new parts.
