I took apart my Yamaha CVP-209 and cleaned the keys. But when I put it back together and turned it on: no sound! I tried the master reset but it did not give me sound, even thru the headphone jack.

Master reset was suggested elsewhere unless it's different with my model. Also, I did make one change--I removed the old floppy disk drive and just tucked the plug-ins and ground wire back into the hole. There were no loose wires involved; just that. Any thoughts? I can reattach that if it's the problem. Thanks much!

    So what are you getting? Power light, screen display, just no sound?

    Try pressing a demo tune - does that work?
    If it does then you may have a problem with the connector from keybed to motherboard.

    If no sound just try connecting the disc drive up again - if this then makes it work it is probably hanging during the start up procedure.

    Report back if you need to and we can try something else.

SOURCE: replacing headphone connector

The impedance or resistance of the two different sets of wires might be different. The higher the impedance the less signal. If your cable is long enough you are better off spending the five or so dollars for a new plug. Red is right, green or blue is left and copper is ground.( Usually) Unfortunately not all manufacturers agree. Also what could have happened is a short between the wires that you soldered.Make sure they are physically separated from each other and insulated.

SOURCE: wire has been cut

My wire was cut, and I made it worse trying to fix it....with several failed attempts... was becoming despondent, but gave it one last try, and was successful. First, each little tiny wire has two internal wires, one green (ground) and one gold (hot). At first, the green one looked like some fiber or filler and I cut it, connected the gold wires and nothing happened. On further inspection, with magnifying loopes, I determined the green fiber was in fact green wire. There was also a lot of clear fiber, which is insulation? filler?... I don't know, but I cut it out, leaving only the wires. From the internet, I determined that the wires had a thin layer of plastic on them for insulation, which I burned off lightly with a lighter, connected the green together, soldered it, wrapped in electrical tape, then connected the gold together, soldered it, and taped again....and to my suprise it worked. I used twist ties, and epoxy to strenthen the area and was done, my headphones are working again.

How do I take the back of f of a Yamaha clavinova cvp 209

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.

Where and how can I buy a replacement keyboard for Yamaha CVP 305M? Thanks, Michael

There is a well documented problem that occurs with the keybed on some of these models due to a manufacturing fault. Take a look at the keys that are sticking. Is the gap on either side of the key the same ? If not then the key normally leans slightly to the left rubbing on the adjacent key causing the sluggish action. The fixing tab at the back of the key breaks causing the spring pressure to push sideways.

You can just replace the offending key but the problem will eventually return. You could replace the whole keybed but this is a very expensive fix.

Keys are around £ 15.00 each.
Replacement keybeds around £ 450.00

Reset button or Fuse on my Infinity?

Ok, I took it apart, cleared the clog out, and put it back together. It wouldn't switch to "carpet". Got no answer on my question. Took it apart again, only I went further. Took apart the bottom - brush out, all inside bottom parts out, cleaned all that part of vac. No clogs down there. Ran the carpet/bare floor switch back and forth several times while I had it apart. Put it all back together and it worked fine. Still didn't find a fuse or reset button...

CVP -303

Hold down top C key whilst turning, this initiates a factory reset so any settings you have made resulting in the smear should be returned to normal.
