Serious problem
« on: September 27, 2021, 06:25:20 PM »
I have a serious problem with the touch screen of my CVP-609. It looks like the touch area has shifted downwards for about 1 or 2cm, e.g if I touch a voice/style or song the upper located item is choosen. I also cannot choose the lowest icons anymore, including the menu icon. Ik already tried to restore factory settings by pressing C7 when switching on. No result. I am getting desperate. Can anybody help me?

Cannot calibrate because cannot get into the menu. If I touch the menu icon the upper located icon is choosen.

I found that the touchscreen area must be re-calibrated but the problem is that the menu icon cannot be activated because the touch area seems to have shifted downwards to much. Is there another way to get into the menu?

Hi Bert,

I recommend calling up the internal Test Program of the CVP-609 and running test #052 Touch Screen Check there. The touch screen is also calibrated during this test. Then you run test #054 Test Exit to exit the Test Program. Maybe you are lucky and that solves the problem.

If not, you could go back to the Test Program and do a full Factory Reset. (However, this will delete all user data, including the entire User drive!)

To carry out the reset, first run test #053 Factory Set. Note: After performing this Factory Set function, be sure to execute #054 Test Exit. At this time, do not turn off the power until ďGrandPiano1Ē appears on the LCD display.

If the problem is not solved even by a full Factory Reset, only Yamaha Service can help you.


Important: In order to run the Test Program, you absolutely need the corresponding service documents. You are welcome to contact me via PM (Personal Message), then I will send you detailed information.


Best regards,
Chris

Good news Chris. Following the instructions of test 52 that you sent me I was able to calibrate the touch screen and to my surprise this solved the problem. Great thanks to you!

Bert!

Iím glad you solved the problem. overover seems to have good knowledge on many problems and is very helpful to forum members. I can confirm that the testprogram can solve several issues if reset does not work. I have a CVP 605 and a CVP 709. And the procedure is similar on both. You have to press a key combination when you hold the on switch down. There is an alternative method on 709. You press three voices simutaneously and turn on the power switch.

Then TEST is shown on the LCD-screen. You have to scroll down the program list to choose what you want to check. On the 709 it runs from 001-056. You can check ROM, Backlight, Pitch, Pedals and so on. But itís advisable to have the instructions as overover states if you are performing this on your own. If sucessful you donít have to call in a Yamaha tech.

The problem was that fingerposition did not correspond with the icons on the touchscreen, il looked like there was a shift of more than 1cm so I could not activate the menu icon at the bottom of the homepage screen and thus was not able to activate the recalibration screen. By using the testprocedure 52 the recalibration screen showing the four crosspoints in the corners popped up and recallibration could be carried out. Thanks to the tip of overover!
I still wonder why the positioning of the touchscreenchanged unexpectly.

If you were in the UK the cause would be obvious - either Brexit or Covid or combination of both because apparently they are the cause of everything. But since you are in Holland itís more likely some complex technical glitch! ;D
