calibration screen problem

SoulBe · Post by **SoulBe** » Sat Nov 28, 2009 7:45 am

from the beginning when I got my OASYS sometimes I had to push twice or into another part of the screen and then back to the point I wanted, but this occurs only sometimes and I never though of this beeing a bug..... I thought of maybe pollution of the screen or something.

By the way .. how do do all clean the screen? Is there a special advice? I don´t want to damage it.

Thanks

sometimes I had to push twice or into another part of the screen
soulb, this was the problem I had in 2007 and I solved it with the
factory calibration, after O. is finished hold down
EXIt, 2, ENTER, FUNCTION
This brings up the O. internal calibration application.
I may still have the pdf file describing what to do exactly.
Anyways, all parts are fine, stick, ribbon, switches, etc.
but the screen calibration with OS 1.3.3. no longer works.

After two months I have not heard anything from KORG,
but at least two users, leo200 and mike conway (creator of the
unofficial O. dvd) have confirmed what I suspected: screen calibration
no longer works, at least not with the older approach.

I am surprised that some of the most active contributors to this forum
(DAZ, SHARP for example) have not reacted: the O. can only be used
if the screen works.........................

Its pretty interesting-somebody can answer: this calibration process should work or not?

I'm sorry that you've had this difficulty. As far as I know, calibration should work with 1.3.3. I would be interested to know how many people have had this problem.

This might be a problem in reading/writing the pad calibration file. If so, my suggestions are:

1. If an update was recently installed, re-install the update. Use "Method 1: Booting from the CD," instead of the Update System Software menu command. Follow all instructions in the update documentation, including disconnecting any USB devices.

2. After (1), try calibrating the pads again.

If this does not work...

3. Back up all user data to CD-R/RW or external USB media.

4. Use the "Format HD, and then restore OS and factory sounds" option on the Restore CDs.

If the problem was with the calibration file, this should fix it.

5. Re-calibrate all physical controls (ribbon, joystick, etc.). For instructions on how to do this, you will need to contact your Korg distributor. I wish that I could tell you directly, but I cannot.

Do I understand correct that you are talking about calibration pads?
We are asked about screen calibration.

Anyway thanks for recommendations!

The same would apply for other calibrations - however, re-reading, I think I may have misunderstood what was meant by "calibration doesn't work."

What happens if you simply use the menu command in Global mode?

Note that you can also use the standard ENTER+menu item number shortcut, if the screen is so out of calibration that you can't select the menu (extreme, but theoretically possible).

We are talking about factory calibration procedure. Which you can access after pressing EXIT,2,ENTER and FUNCTION together.
It's probably doesn't work with 1.3.3 OS

The original question was about screen calibration, which does not require the factory calibration feature; you can do it directly from the Global screen.

I can't answer questions about the factory calibration procedure (although I wrote the documentation for it...<sigh>). For that, you would need to ask your Korg distributor directly. However, again, screen calibration does not require the factory procedure.

rudolfck notes that he has to push very hard. This is not related to calibration, which only deals with the x/y axis. If he has to push very hard, that sounds like a hardware issue to me, and I would recommend that he talk with his Korg distributor's technical support department - as I recommended back in September. According to his posts in this thread, when he contacted them, they recommended that he take it to an authorized service center - which would be my recommendation, too.

Finally, if anyone ever feels that product support is taking too long to respond, I would strongly encourage them to contact them by phone, as opposed to by email. This lets you talk with someone in real-time, which can sometimes make communication much faster than back-and-forth emails.

the factory screen calibration did much more than just
touching upper left and lower right corner.
As I remember the screen changed colors many times,
amongst others, and there were more squares to touch.
This at the time solved a problem I had with the coordinates
which were all off set so you had to touch next to a button
etc.
I also seem to remember I had a pressure issue which
was resolved with the factory calibration and not with the
global/simple one.

Anyways, I have now heard from two user (mike conway and
leo200) who checked for me, and confirmed that the screen
calibration in the factory mode does no longer work but
nobody from Korg has let me know that I am right.

Before spending lots of money (Hawaii is a difficult place
for having the O. serviced) I would like to try the calibration myself since I know how to do it.

So why is it so quiet from Korg? It appears they
do not like to ackowledge this bug/problem.
Something is wrong I think
in 1.3.3 unless now there is another secret code to access
the calibration for the screen.
As it is, the O. freezes up and has to be scwitched off.
If anybody has a problem with the screen that needs some fine-tuning and is lucky enough to get the instructions from
Korg and they are the same as before (same 4 buttons)
will find that it DOES NOT WORK.

I am sorry I repeated my story again.
I will now simply ask danatkorg who works for Korg and knows
a lot about the O. to verify that under 1.3.3
the factory screen calibration is no longer functioning.
That would be nice to know and maybe is also of interest
to the Korg support people.

Thank you.

I just tried this, and it worked fine. There are three squares: upper left, lower right, and center. I believe that the center square is actually unnecessary, which is why it is omitted from the Global mode calibration.

Yes, the Global screen calibration will do the same thing.

I can believe that you felt that something improved, but the calibration will have absolutely no effect on this. It deals with X/Y positioning only. I took the time to confirm this with one of our engineers today.

The calibration application is not officially supported for end users. As with any such unsupported and non-public testing/diagnostic functionality on any product, you should expect that it may not function intuitively, and that it may change or disappear at any time.

I'm going to make an exception to my rule of not discussing this feature, with a few notes relevant to this topic.

First, the instructions for use do not include calibration of the LCD; instead, they specifically advise skipping it.

Second, the beginning of the instructions reads:

DO NOT TOUCH ANY BUTTONS OR CONTROLS
OTHER THAN THE ONES NOTED BELOW.

In other words, using the LCD routines in the calibration app specifically goes against the instructions for use.

It is also unnecessary, since the Global calibration menu command does the same thing.

My recommendation for you is to try the Global calibration function first. If that does not work, then it may require service, and I would recommend calling Korg USA to talk to product support in real-time.

Best regards,

Dan

There appear to be three Korg service centers in Hawaii:

Hopefully one of these can help you out, if repair is necessary!

Well thank you for checking.
So under 1.3.3 the factory screen calibration mode works for you
but not for me/leo200 and mike conway?

I guess you have a diiferent system than the three people
that got the blank screen.

I will not pursue this any further. If you say pressure
problems cannot be solved with the calibration then
I will have to have it fixed somehow.

Regards
Rudolf

My guess is that the three people who report a "blank" screen saw the same thing that I did. It's an LCD test and calibration routine. You tell it to start, and the first thing it shows you is a screen full of white pixels. When you advance, the next screen appears - full of black pixels. And so on.

The calibration routines are carefully documented with an end-user in mind, for the specific case of restoring analog calibration on a system with a freshly formatted drive. As noted in those docs, everything else in the diagnostic routines (such as the LCD diagnostics) should be left alone.

I want to reiterate that I'm sorry that you're having problems with the screen. I hope that the calibration routines available in Global mode can help. If not, please give a call to Korg USA so that you can talk to their product support people in real-time; they can help you to troubleshoot further.

Ok I have been able to go through all the steps;
it is different than before...
I do not see the rolling colors up/down, left/right any more
(as I recall) and what used to advance automatically
needs now some prodding.
the word `advance' in your last post gave me a clue
and now I get by manually advancing (I guessed what
button to press):

white screen
black screen
contrast test
brightness test
three green squares to touch
buzzer test

The touch calibration required far less pressure than in
global mode and I think the screen reacts better now,
but that may be subjective.

Nuf said. Bye and thank you for your replies/reactions.
