lost contact in joystick again

KrzysiekK · Post by **KrzysiekK** » Sun Jun 29, 2008 8:28 am

I've been playing with joystick for a while and suddenly noticed that pitchbend message isn't transmitted anymore. Seems like I need to open the cover again and solder the X cable... I wonder how to protect it from loosing the contact.

Best regards,
Krzysiek

It seems than when you are attaching the cover back some of the wires get caught somewhere in the range of X or Y axis movement. (Usually in Y axis' range)

Try to tape them somewhere on the plastic chassis in order not to be in this vertical movement's range but be careful. You must ensure that the cable will have enough length untaped so as to move freely otherwise the joystick will not go up/down to its limits or the wire will be cut. If you do not have tape try to tie them up using those white plastic components that are already in the instrument to tie up cables together (I can not find the exact word in English-perhaps they are called clasps-press studs, fasteners...whatever).

Cheers

Thanks, the problem occured after some more demanding joystick movements

But I doubt I tore it off; it is rather because of thousand moves and the wire simply lost connection. So probably same fault as before, I am going to check it today.

You must ensure that the cable will have enough length untaped so as to move freely otherwise the joystick will not go up/down to its limits or the wire will be cut.

There is enough space and the wires are long, no worries here. I will use thermal pipe covering both the plug and the wires as well as isolation tape, to spread the tenson when the thing is being moved.

edit: I gave it an another day, so today maybe

That's even better!

May this be the last time you open the cover...

Cheers

Thanks korg_nikos

I fixed it today.

Same brown wire:

OK, it doesn't look good... even worser, I hoped there will be a better way to fix it but all in all I don't complain and I hope this solution is enough:

Best regards,

KrzysiekK,

if you continue this way, soon you'll be able to service our Korgs. Or you'll force Korg to release Special Korg Triton Extreme Build-Like-Tank.

Speaking of which, I would require your skill - my numeric field keys, usually 4 and Enter, work with some difficulties. Every other key require the slightest pressure, just easy finger touch to respond, but 4 works only if I press it on the button's left side and Enter behave strangely, sometimes it works perfectly, but sometimes I have to press it few times to get a respond. I don't think there is some problem with connections or something like that - place I use to gig in every weekend was fairly dusty and my board was covered with dust each time I finished the play. So i suppose some of the dust got into space gaps around those buttons. I tried vacuum cleaner, didn't help much. What should I do? Is there any spray or something, not aggressive to contacts and electronics, which could eliminate the dust?

shrike, please do not exaggerate

I think these kind of parts are rarely being cleaned, they are cheap and I belive it not hard to replace them in TEX (although some buttons are hard to press to take effect to me as well, I didn't checked how things look inside, but it doesn't look that bad according to the video - there is a user who posted link somewhere on korgforums to the video regarding his Triton Pro repair). This is what I did with my Yamaha switch when it required much pressure to take effect, and I can confirm what You say - when You try to press the switch in different area, it is sometimes working better, sometimes it doesn't; working very well/light after replacing. If You still want to clean it, then look around for a special kind of spray, as there are many of them for different kinds of contacts. I made a phone call and was adviced to choose among products called "AG Kontakt", which might be native here, in Poland, but anyway here's a link for one for specs: http://www.nowyelektronik.pl/searchskle ... s&nr=20188 sorry I have no time for translation (@ work currently and I am just in a hurry

Thank you KrzysiekK, no need for translation, I got the picture and I understand your language a little, will try to find something similar in my place. I really don't want to dismantle my Extreme, suppose I'll do fine with this kind of spray.

So if you get this spray and suppose that you have some buttons that they don't respond as they should and you don't want to dismantle the board, where are you going to spray?

Are you gonna do it in the gaps between the button and the plastic cover?

My jog wheel on both the Ext and the Studio misbehave. Anyone have problems with that??

Yes, it definitely requires to be opened; actually I am affraid these microswitches have to be dismantled as well, not good news and I don't like this kind of thing either

but this is probably the reason why people do not recommend cleaning these things but replacing instead. Maybe that is not simply a dust during gigging? Or maybe I misunderstood shrike - the problem may be not with contacts but with dust around button (in such case the spray won't help, it is for contacts only)... I don't know but - according to the switch construction - it shouldn't be the case.

Best regards,
Krzysiek

Yes. Actually I do think there is problem just with a little bit of dust that got between buttons and casing, causing buttons not to respond evenly where ever I press them. But if you guys think it may not do trick to apply some spray that would eat the dust, I will get it to someone to clean it for me. I have no intention to dismantle my Extreme on my own.

I did dismantle my extreme yesterday because I had the same problem. When I used my joystick in the x- direction, the pitch bend occurred correctly only when done very fast. If the pitch bend was done slowly, it stayed on the same note untill lets say -50% and thats ofcourse not wishfull when playing a synthlead solo.

So I decided to take a look but I didn't find any bad contacts and I used some contact spray for the potentiometer but since the design of this component is closed, I don't think that was the problem. Are there other components that can be broken or should I replace the potentiometer?

Grtz, Wilbur

My joystick is kinda loose and bends to -X and thereby bending the pitch of the note that i play. This happens when i play it slowly.

If i open it up, will i be able to tighten the joystick (once opened) cos it seems its just loose. Please let me know. Based on the above pic, it doesn't seem possible.

thanks
