I have a Triton Pro and the touch screen is getting a little sluggish/unresponsive. I have found a replacement touchscreen for around $250 but that's a lot for a part that I'm not even sure is the root cause of the problem. Was hoping to connect with another owner who has seen the same problem and fixed it. thanks!

replacement touch screens can be had for £60

if its just the touch screen sounds like your paying for a new lcd screen and touch screen combo which cost the $250

have you tried to recalibrate it first as some times thats all thats needed

also make sure there are no dinks as if there is the screen keep jumping to where the pressure is

i always found there was a bit of lag between the touch and the actual movement of the screen

my trinity is the same and i get the occasional line flicker on

I think you're right - I think it's the whole enchilada. I was doing a little homework and there seems to be some 3rd-party touch screens but they're not OEM parts - seems like they need some surgery in order to install properly. I was hoping to avoid that if possible.

There are no dings or scratches on the display. I am the original owner - the synth has never left my studio. It's about 10 years old I guess. Has seen modest/moderate use here but nothing like you'd expect from a touring piece of equipment being used very often. Not like that at all. I couldn't estimate the number of man hours on the screen but I would guess pretty low. Most clients are happy to just hunt through the stock sounds using the buttons and dials and not the touch screen. I've probably used the touch screen more than my clients. I remember it being very responsive when I first got it. Now it takes a second or two for the thing to register a finger poke. Forget trying to drag the scroll bar - hardly works at all now.

Which brings us to recalibration. I don't see that procedure covered in the user manual. Can you explain the procedure (if it's not too much trouble)?

Thanks!

Umm - I found something in the Parameter Book that discussed touch screen calibration. You touch at the upper left and bottom right and then hit Done. That's it. Is that what you're talking about? Didn't seem to make a difference though.

Forgive my ignorance if I’m wrong, but many times there is a battery behind it all, and if your battery is drained of power, it could be the problem. Is there a battery in this one?

I'm 99% sure there's no battery inside the Triton. It's the 1% that scares me lol

But I'm confident there is no such battery backup. If there was a battery, and it went south, I would have thought it would have manifested itself as a problem long ago. I've owned this thing for over ten years as a studio-only instrument. It's never been moved out of my studio for any reason. Since there doesn't seem to be a magic bullet solution, I'll just leave things as-is for now and see how the wind blows. If it gets worse to the point it doesn't work at all.... I'll bite the bullet and buy the $250 replacement option and hope that fixed the problem for another 10 years or so. It's a fine keyboard in like new condition and worth the effort to keep it running.

Arrghhh ...
What´s up w/ the interwebs and PlanetZ ?

Ask 1st,- then do a search yourself ?

https://www.google.de/#q=Korg+TRiton+Pro+battery

There´s ALWAYS a battery in every hardware keyboard instrument which offers preset memory and this battery comes rarely as a rechargeble one (like in a Sycologic MIDI matrix switcher p.ex.).

Bud

I even buy back up batteries.
Don't want to get stuck again, but that was back when Casette Tapes had the factory presets and were as slow as Samples over MIDI......arrgghhhh.

they use a cmos battery

here is the service manual

the battery deals with the calender and time and other parts

if the battery is low it could be that the calender and clock are not correct

and maybe why its slow but only changing the battery will tell you this

if its still slow after the battery change then there is a fault else where

Thanks for sharing the service manual - that's very helpful but I don't see any reference anywhere to a battery in any of the drawings or parts list (unless it's not specifically identified as a battery). There are a number of Triton models perhaps the original "Pro" model didn't have one? I'm not aware my model has a clock or calendar feature. I don't see it on any of the usual user screens.

Regarding the video links - also helpful but apparently the standard "Pro" model doesn't have a battery in the same location (if at all). I removed the cover on the bottom of my unit and see no such battery in the location indicated in the video. I suppose it's possible (if there is a battery) that it's mounted somewhere else inside the unit. There is a second smaller chrome cover on the bottom of my unit where the memory modules are installed but no obvious battery there either.

If I have time I'll open the unit and take a look see. In the video it looks like there is an obvious low-battery error message that pops up n the user screen for that model. I've never see an indication like that on mine.

need to check your generation model as some early models never had batteries while others did

if yours has the battery its soldered onto the back of the main board

you have to remove the mainboard to see it

if there is not one on your mainboard then you have the version with out

this is the same mainboard as used by the karma keyboard which also does not have a battery

this version has a cap that does the job of the battery

so your best bet is first check the mainboard

if no battery get the psu checked for ripple on the dc lines

and check the cap for leakage by the flash ram

This simple replacement cannot cost you much in the shop; you can let somebody used to do this kind of job change the battery for you. They cannot charge you much for it. Anyway, it’s a good idea to change your battery regardless, even if you fix the problem through other means, everything should work better afterwards. User banks, as far as I know, sometimes depend on a battery and if the battery dies you lose your personal parameters and presets, this is my case for instance, my Korg X5 depends on a battery to save and keep your personal presets.

lol Thanks guys. Nestor I'm going to print out your reply and hand it to the service tech after he tries to charge me $500 to replace the battery including shop supplies like rags, solder, replacement soldering iron tips and the little sponge they use to clean the tips lol

I suppose you are not joking and this is the actual amount they have asked you. Well, it sounds like a joke… How can they charge 500 for such a simply thing? Dump them and go elsewhere…, and instate of the first message, print and handle them this one!: "People, you are gear gangsters!"
