++Gear Down!++ Repair Thread (Page 5 of 14)

Hi! I'm so happy - she works again! I opened the bass station before, right after "the accident", but nothing changed. So after your regards I checked everything (+connections within) again, put every single knob on standard position like explained in the manual, reseted the sounds and so on - now everything works again! Yeah!

Sometimes I get very confused in fact of those "little" bugs, because I have no technical knowledge and fear the worst. Thanks!

I also have a 101 problem to tag on in case there are experts about.
When NOT in CV/Gate mode, the 101 will randomly turn the arpeggiator on and off. This sucks when playing a sequence, arpeggiating, or just plain not using CV. You know how when you are running it off batteries and they are getting low and that red light turns on.... it's like that.. sorta, but when it's actually plugged in to the wall. I am guessing this could be a power thing?

@rsprats: so the problem was probably in one of those contacts you checked. sometimes disconnecting a connector and then connecting again solves the problem.. those contacts oxidyze over time and by doing this, you scrape off the oxidation. good to hear its back in business!
your 101 sounds like the keyboard contacts need a little cleaning.

@honey peters: nope. cold solder contacts on the little board that holds the buttons. open it up, take the connectors of the small board off, and take it out of the synth. resolder the contacts, plug back in. i fixed one for Fre2k that had the very same problem..

@ben jbx: rotary encoders going bad are a nightmare. you need to have the exact same part, otherwise all kinds of weird things can happen. this problem is now starting to come up, as gear with those things is aging. my lexicon vortex has one bad encoder, and you can't just replace them with any other one that has the same dimensions.. there are hunderds of different ones, you can try to find the part number and searh places like digikey..

@rude, thanks for the advice. I emailed TC and they put me on to thier UK service centre so hopefully they can sell me a like-for-like replacement.

The faulty part i took out is an Alps controller with '4NN' stamped on the side, but no other info apart from the manufacturers name. I can't find anything in the Alps range that matches that part so maybe it's a special run or something. Here's hoping the service centre can hook me up.

Would that be Panic music? Cos if it is they are superb! Highly recomended..

@basscakes, who did you go to for the replacement parts? The UK service centre (it is Panic Music) are telling me TC won't ship parts to end users, and I need to send it to them for repair.

I don't really want to send it off to them, it's a lot of grief for a 2 minute soldering job.

are those rotary encoders? this is exactly the behaviour of a dirty encoder. making weird connections and giving strange bouncing values all over the place. you can try resoldering, but i'd first give them a good blowout with air, if that doesn't work use some contact spray.. (you may need something special for encoders, i don't remember).. for my lexicon, this has worked until now, though there is one preset, no 15, that's unusable because the machine starts to blink suddenly..

if that doesn't work try resoldering, if that doesn't work, replace..

plugged in the juno-6 after a spell of it not being used.  worked fine apart from the chorus.  buttons lit up but no chorus.  left synth on, went to shops, came back and the chorus is working but now one of the voices seems to have dropped out.   wtf?  I know the 106 has a common voice problem but does that apply for 6's or 60's as well?

nope. they don't have the parts that die in a 106.
this will be a different problem.
and probably a lot cheaper to fix.

time for a tech!
:-)

pff.. i had my mk1 syntecno teebee all opened because it was acting weird. its loosing its settings for the cv/gate and midi channels, and now it was even resetting its own filter settings. after a lot of testing, it turned out to be not the teebee itself, but the $^&*^$$## midi controller keyboard that has dirty controller pots, and is constantly sending out random controller data.
the teebee loosing its midi etc settings is a more serious problem, apparantly there's a ram in there with an internal battery thats empty and can't be replaced.. so i need to feed it a sysex file every time its switched on in order to work.

cleaned out the keyboard control pots, but its cheap plastic junk so well see how long it lasts. and the thing also refuses to send out midi via usb.. but if i plug a midi cable in, it works...

i'm no fan of novation stuff.. i had their midi controller here for a while (that new big one) and it was also very sloppy put together. this keyboard is an evolution, and it does the same with the silkscreening.. it all disappears. and something is wrong inside, youre supposed to be able to change the ''midi via usb'' function between ''yes and''no'' but it stays stuck in ''no''.. its also not recognized anywhere in my software, i can only use it as a midi keyboard via a midi soundcard.. cheap junk.
