calibration screen problem

rudolfck · Post by **rudolfck** » Wed Sep 09, 2009 6:53 am

Hello, in certain areas my screen only reacts to a lot of pressure.
The standard calibration in global mode (touch two green squares
left top/right bottom) does not change a thing.

So I thought I would go into the factory calibration mode one can enter
with the aid of the function button (only function it has as far as I am
aware) and all the tests (fan control/AD converters etc.) work as
before but not the LCD calibration. Before (a year or two ago I did this once)
I got quite a light show and then if I recall correctly a lot of squares to touch.
But now I just get a bright screen and I have to turn off the
machine. So has something changed with the later operating systems
(I have the latest) that anybody is aware of?
Can anybody familiar with this calibration (4 switches to hold down) test it to see if they also just get the bright screen
but nothing else? (turning off at this point does no harm I found)

It's a while since I did this, but as far as I recall it's like this. From the Combi page press these 4 buttons together.

press EXIT,2,ENTER and FUNCTION together in that order and wait about 10 seconds until a test dialog box pops up. Then use the INC/DEC keys to scroll through the calibration options to the LCD test page. You should see a few boxes on the screen to touch and get feedback to show that each one worked. Press ENTER when completed which saves the settings and switch off the Oasys. If in doubt, don't touch anything and just switch off the Oasys and no settings will be saved

There are options to calibrate all kinds of stuff in there, and pressing ENTER saves each section but don't do anything which may screw up your settings.

I as trying NOT to give the combination but now the cat is out of the bag!

What I was asking is if somebody could get to the LCD
calibration part and see if that person also gets stuck in the LCD part
like I do. Point was, I do not get the boxes, nor the screen changing colors
etc. Just a frozen bright screen.

For those that do not have the pdf file that describes the procedure:
do not enter the combination EXIT,2,ENTER and FUNCTION on the O!!!

OK steve maybe you can check if you also get the frozen screen,
apparently you are familiar with the procedure too.
Anybody want to try?

I am just worried about my LCD.

I will check for you tonight.

As the Oasys is now a discontinued product and the pdf file seems to have found it's way around the world via the back door anyway, I can't see why it's considered to be such a big secret. The full service manual ( at least 2 versions that I know of ) and the calibration pdf are available on the internet if you look hard enough. Maybe they should be published on this forum and have done with it !

I agree that entering the calibration pages may have it's risks if you don't understand fully what you are doing, but if you own an Oasys that's not under warranty and you need to fix a calibration issue what's the other alternative ?

Thanks in advance for checking.

I guess you are right: the calibration procedure may as well be made
public.

I have the same problem.Will be happy if calibration will fix it. Who can help us? BTW- in calibration mode I got the same bright screen without nothing

For all such issues, I'd recommend contacting your Korg distributor's technical support department. (e.g., Korg USA, Korg UK etc.) For phone and email contact info, please see the link in my signature.

Best regards,

I have provided an unofficial firmware update for Korg MS2000 users for years and I insist that people contact me to get it, rather than just posting the files up on the net to be downloaded. That way I know for sure that anyone using the procedure knows how to contact me and I know they are being sent the very latest version. That wouldn't happen, as I know from experience, when you just post a file on the net. Invariably someone takes your file package, posts it somewhere else, removes your contact information or the usage notes and also doesn't ensure their version is kept up to date with the source version. It's harder work for me, but I am very keen to ensure no one f**ks up their synth

I suspect that for very similar reasons, Korg release the calibration procedure only on request. It's not just to keep it secret

So if you're gonna do the calibration make sure you have the latest documentation from your local Korg support people, and that you have at least some introductory relationship with them in case you need help with it.

2c,

Daz.

I have mailed Korg USA for advice.
I did get the instructions a few years ago directly from Korg btw.

I doubt the procedure has changed since all steps are
still there and work fine except the screen calibration.

Please let me know if you'll get acceptable resault

rudolfck, I was given instruction from Korg on this about two years ago. I cannot imagine that the prcedure has changed but if indeed it has changed with the past updates would you please make a follow up post that the procedure has been modified.
Thank you.

I would like to bring this up again:
after waiting a month for a reply and then mailing again I got the standard
reply

Thanks for your inquiry. I recommend taking it to one of our authorized
service centers for repair.

I asked brian rath of Korg support then if it could he could verify that under 1.3.3 the factory
calibration mode fails when it comes to calibrating the screen.
I havr waited another 4 weeks for a reaction, but none arrived.

Also I have not heard from any other users that they have the same
problem (except lleo200). If a few people experience the same thing I can conclude
it is not a hardware problem per se (the screen) but a bug or something has
gotten into the built in calibration mode..
Please somebody check, the screen is very important and I need to apply
a ridiculous amount of pressure here (in fact the standard calibration in global is tough already, I hav to push very hard on the two green blocks
and then push realy hard on `done')

I would guess that korg would tell the service repair folks to use the
calibration mode anyways... so they would be stuck too, just guessing...

Regards,
Rudolf

I have now in stand Oasys and M3. And have to say that on M3 I dont need to push screen twice or more as its occurs on Oasys.
Is it calibration problem? Hardware problem? Bug?????

Pretty sure that users cant resolve this problem by themselves.

wrote leo200

Well, point is that two years ago I had problems with the screen which was
resolved by myself after I received the instructions about how to enter/use the
factory calibration mode (Brian Rath of Korg support sent it to me after I
pleaded a bit, Hawaii is not close to anything and with no warranty left,
this saved me a lot of trouble and money and it was really easy too).
So, if the calibration procedure for the screen still worked I had hope to
fix it myself, but it appears no longer functional... at least on my O.
and apparently too on leo200's O. Somebody else in this thread said
he/she would check but I never heard anything. Are there any others
that have checked the calibration for the screen and get stuck with the
bright screen and a frozen O.??

It is anoying that Korg has not sent me any word about whether the
calibration procedure should still work. This ominous silence
makes me worry that there is a bug that they wish not to
ackowledge). Well, at least leo200 also had the
white screen. That is two data points! If a few others could verify it then
I am certain that something has changed in a bad way for everybody who
at some point needs the advanced calibration for the screen without having
to ship and pay for something that in the past could be done at home..

I guess I could re-install an old OS (1.1 or so) to see if I am right, but it would
be such a hassle..

Ok Aloha

I tried it and also got the white screen. It doesn't appear to work with this OS. I turned the O off and back on. Now, I'm back to my normal display.

The size and type of screen seems to be totally different on the OASYS. I had two Tritons, when I first got the OASYS, and noticed that their screens were easier to handle. I think a lot of that has to do with how small the pressure zones are on the OASYS screen, compared to the smaller screens of a Triton or M3. An OASYS screen packs twice the info on it and there are a lot of zones.
