Posted: Mon Mar 06, 2023 9:56 pm Post subject: Korg Pa700 Touchscreen hard problem |
|
|
Hello everyone,
I am the owner of a Korg PA700 arranger, whose acquisition was motivated by the very pleasant experience of playing my music on a PA300 from 2016 to 2020, which unfortunately I had to sell to acquire the PA700. Subsequently the PA700 began to show erratic behavior on the touchscreen, suddenly changing the execution settings and blocking areas of the screen rendering them unresponsive.
After much research on this problem and visiting the service center twice, unfortunately I realize that there are many PA700 arrangers that show this problem with the Touchscreen and that even the Korg service centers in different countries do not have a satisfactory solution since many users report having changed power supply, touchscreen and even motherboard, also going through recalibration procedures, operating system and other software recipes, and still the problem continues such as the case of mine.
I want to make a respectful appeal to Korg to help us solve this important problem that many Korg PA700 owners have. Even with a device out of warranty, I think that Korg can do a lot for us if they gives us the indications for a correct solution to the problem. I honestly think that the problem has not been properly documented and therefore the service centers do not have a proper solution for this problem.
I'm not asking you to give us a free solution, but one that allows us to preserve this wonderful and incomparable musical gem.
Kind regards |

I am sorry Albertano but you have more chance of going to the moon than Korg helping you. Four arrangers, three of which are obsolete and one that does not work.
Best to move to Yamaha or someone else now Albertano if you want to enjoy your music for the next few years. Sorry.

Thanks Taichi.
Unfortunately I think you're right, I've been battling this problem for more than two years.

I sometimes have a problem with "ghost touch" on the lower right corner of the screen of my PA700.
Suddenly a screen opens as if I touch MIC/LINE settings from the main screen.
But it is not always the case. Mostly there is no issue. Maybe a problem with static electricity ? (my PA is not grounded). |

Thanks AdeG.
Ghost touch is an excellent description, it seems to me that someone is touching randomly the touchscreen and then suddenly the lower right button of the screen is selected.
First I tried grounding the electric supply, later the technical service changed the power supply and then the Pa700 worked fine for 3 months. Unfortunatelly the problem is back again.
A bad grounding could be the reason for this problem, but in the same line and under the same conditions I have another Yamaha keyboard, a Soundcraft mixer, Cerwin Vega monitors without a problem of static interference in sound reproduction and in general all of my low power electronic equipment.
I'm going to try another perfectly grounded voltage regulator and I'll tell you about the result soon.
Thanks for reading and commenting. |
