Try another card,if that doesn't work then the device is defective.

It should be a momentary normally open

If all A & Eb are dead it would point to either a bad connection between the keyboard circuit and the motherboard ( ribbon cable ) or possible diode problems on the keyboard PCB. Initially open up and check connections are all tight and correct. Did this just happen or has the keyboard been opened up?

To start with try a master reset, whilst the instrument is off press and hold the top (highest) sounding key whilst turning on. When the screen displays Yamaha release the top key. If this doesn't solve the issue then it could be a number of things as the keyboard does a self check on startup and will hang if a fault is found. Check each rubber switch is not stuck down or even missing this can cause this issue. Please report back either way. Dan Becketts Music Ltd

Hi Assuming you mean YPT230 unfortunately this model does not support dual voice according to the user manual. https://www.strumentimusicali.net/manuali/YAMAHA_PSRE233_ENG.pdf

I will answer the question! To get inside you need to find the 2 screws hidden under the top panel, remove these and the top cover can be removed, everything else is then accessible. If you don't know where the screws are chances are you will never find them. report back if you need more help. Dan

Lets answer the question. Which button is not working? It normally means as suggested either the carbon under the rubber button is worn or in some cases the circuit board is damaged or worn. Try to replace the button first as the cheapest option. Report which button and I can send you details of the part number needed either by number on the attached or by which function it does eg tempo + / -

1969, Depending on condition, these can be quite nice instruments.

Do you mean the DGX-640? To my knowledge, Yamaha doesn't have a D6X line of keyboards. Most of Yamaha's manuals are available from their support page: http://download.yamaha.com/top/?site=usa.yamaha.com&language=en . The DGX-640 support page is http://download.yamaha.com/search/product/?language=en&site=usa.yamaha.com&category_id=16084&product_id=1056822 . Scroll down to find the owner's manual in various languages and other documents. Yamaha provides javascript links to the manuals on the site; these do not resolve to specific direct links in my browser history. I hope this helps. Cindy Wells

Likely one of the cables to that manual has either oxidized contacts or come loose. This could be at either end of the cable. With it in "failed mode", try wiggling the cable(s) going to the upper manual and the problem MAY show itself.

Not likely iit is a fuse. The keys are likely scanned as a matrix with two contacts per key. You need to get a maintenance manual for thee organ. Contact Yamaha America parts for music products. They may have the service manual on CD... they used to get $15 for the CD of the manual. Unless you can find something simple like a cable knocked off this could be hard to troubleshoot.

When you say changes by itself - please describe. Try a factory reset : Hold down highest white key whilst turning on. If this doesn't solve the issue please report more details.
