Posted: Thu May 17, 2012 7:37 pm Post subject: LCD touch screen problem, desperately needs help! |
|
|
HI, I am needing some big help here so please read! Thanks
My O's LCD 1 day decide to stop response to my touch...
Turn on, power ump everything look good but when I touch LCD, no response at all. Move all the faders, no move on LCD. Note that I still can with buttons, play sounds... only LCD having a problem.
Panic, I tried to search forum for a fix... so "Enter + 0" won't do anything (how to do it anyway/routine?, I tried so many time but still look like normal boot)
- I tried to insert an OS disc and reset memory, no work
- Then I tried to re-install the OS, re-authorize, update to 1.3.3... but no help
- Go Korg website, search for local authorized "service center", some "not expertise on Oasys", some not return call at all after "technician is busy"
Please advise me...is any other way to fix at home?
Or if I have to get it fix, who should I call and where to ? I definitely don't ant to ship because there is no way that I can ship a 88 Key monster anywhere due to size and weight.
So, please suggest me a good "authorized service center" - I want a real one ...last time I bring my Yamaha CS60 to similar "service center" they charged me $150 just to inspect and later answer to me that they can't fix it
I am living Orange County, 45min to Los Angeles...
Thank you very much, my life very depends on the O

Sounds horrid - feel your pain
Has your O been opened up recently? Any chance something has become disconnected (one of the ribbons for example)?
How does the screen respond if you try to recalibrate it? _________________ Plugged in: Fantom 8, Jupiter-X, Jupiter 80, System-8, JD-XA, V-Synth GTv2, FA-06, SE-02, JU-06A, TR-09, VT-4, Go:Livecast, Rubix44, Shure SM7b, Push2, Ableton 11 Suite, Sibelius, KRK Rokit 5, |

Hi
It sit still and was working no problem, no open, no moving, no abuse LCD just not response to touch so I can't calibrate it (Global the enter + 3)
Thanks for your concern!

Quite alarming!
Korg repair is inevitable.
But does Korg still have replacement parts for the OASYS touch screen?
Please keep us informed about the further development of your sad case.
Good luck!

If you've never opened it, I think it's worth a look inside to check the connection from the screen. Just 2 screws to take out (top screw, near center, on each endcap).
While it sounds like you've had a tough time with repair techs, there are a lot of them in your area. Maybe Sina, or someone who lives nearby, will chime in with who they use... |

Thanks
I remember I open the O and change the battery once, but that was year ago and I remember unscrew 2 from the side...
Is there a way to open on top as you said? can you tell me more about it?
Also, can you tell me more about the tech? (Sina)
Regards

Yes, that's how you get in.
As for "Sina," he is another user that lives in your area. I was just hoping he, or anyone else from that area, would maybe chime in about techs in the vicinity. |

I am going through the same problem with my touchscreen. I have an email sent to Korg Support. It appears they are now only open from 1-5pm eastern time. They close before I can get home from work to be in front of my keyboard.
I have looked at the part number of the Display on my keyboard and it is
NL6448BC33-59
I found an online parts supplier in Oceanside CA from a thread in the Karma forum that sells what I think are used displays for $65, if the display is the problem.

It's interesting that fader-movements are not mirrored on the LCD. This IMHO points in the direction of a lost connection ... as was mentioned already. The standard complaint on the touch-screen is that it doesn't response to (all) touching. But this case is very different!
Let us know what happened in the end - thx. _________________ www.charliemclight.com/en/home.html

I was wondering if the OP was saying that when he tried to move the faders on the LCD there was no movement.
He said "when I touch LCD, no response at all. Move all the faders, no move on LCD. Note that I still can with buttons, play sounds... only LCD having a problem." That would be worse if you physically move a fader and their is no response on the the LCD. |

I'm more familiar with the KRONOS than the OASYS, but hopefully I can assist a little.
As another user suggested, the fact that the LCD screen does not respond to movements of the faders on the control surface suggests it's not a problem with the LCD itself. Also, resistive touchscreens tend to not fail completely at once; rather, they degrade slowly over time.
I suspect that there is a separate module for digitizing analogue controllers - including the faders and the touch screen - that then connects to the x86 motherboard in the OASYS. This module probably connects to the motherboard via a simple USB connection, and if this connection becomes loose, you will have the exact symptoms you're describing.
As I say, I don't have an OASYS so I'm not particularly familiar with it, but I'd imagine it has a very similar architecture to the KRONOS. It might be worth carefully opening up and checking these connections.
If all connections are secure, then the ADC for the control surface has probably failed, but this is much less likely overall. _________________ Current Equipment:
