Turn the keyboard off, unplug it, take out the batteries. MAKE SURE YOU DO THIS STEP BEFORE PROCEEDING! Remove the metal plate under the octave you are having trouble with. Get a can of compressed air, and GENTLY use it to blow out the strike pads (the part of the white key that hits the computer board) Reassemble and power it on.

Some keys are not working

This sounds like something was spilled into the keyboard and shorted out some circuitry. The relays or contacts points of the nonworking keys can be dirty or corroded. At the back of the key, I would check to make sure the key is actually pressing the contact to make sound. Plastic keys become brittle if stored in attics or storage buildings. I'm just running through my thoughts of things to check.

Dead keys yamaha psr e413 keyboard

Dead keys on Yamaha PSR e413 keyboard: Flip keyboard upside down, remove cover screws (use marked cardboard template to remember where they came out), spray suspect key-contacts with fast-drying contact cleaner, (usually a PCB with a matrix of contacts under keys), re-assemble base cover, wiggle faulty keys as far as possible to 'scrub' any dirt or oxidization. If this cleaning trick doesn't work, get a pro to check it.

I have a Roland Plus 70 electric piano (1982 era). A number of black and white keys have stopped working, from the left, white key 10 through to 16 and black keys 7 to 12. Initially, turning the power...

The key contacts have gotten dirty or worn. Most Roland keyboards use conductive rubber contacts that are pressed against circuit traces underneath the keys. These can often be cleeaned to restore operation, but this is not a DIY type project. The cost of repair probably exceeds the value sorry to say and parts may not be availablle... In this case I would probably recommend you get a newer unit as they have many decent synths now for a little over $100 and repair would likely be several times that. Also look at the used market and MANY thrift stores have units... make sure you test any for operation before buying. If one can afford $250, here is a candidate with 76 keys: Also you can search Ebay but do be careful of used items that have no guarantee.

After transport the keyboard,half of the keyboard below c4 not work.

Probably a cable has come loose inside the unit. The keys are scanned by the internal processor as a matrix of two contacts per key. Often the keyboard is divided into two sections.
You will need to have it repaired or if you are electronically adept, open the case and look for obvious problem.

I have a CDP-100 and need disassembly instructions for access to internal keyboard assembly. Unit was dropped while unloading from car. Now some keys are akimbo and won't play as though they are off their...

I just fixed my CDP 100 which had a similar problem - dropped and two keys not working up one end.
1. Lay keyboard upside down on soft surface. Under keyboard is plastic cover held on by 17 screws. Remove all these and lift cover away. The metal key ends are all revealed.
2. Locate the disloged keys. Carefully press them back into position - they will "click" into place. Make sure the corresponding key on the keyboard isn't stuck in an "up" position - you may have to remove the metal key part and replace it again while making sure the key is correctly seated.
3. Replace cover and screws.

I have a Yamaha PSR-170 that has a jammed key

Most keyboards of that scale are not especially fragile. You may have to remove the back (lots of screws) and maybe a bezel that is across the top of the keys to get full access to the keys. The good thing is you have lots of working models --- all the other keys. So carefully consider the differences. It may be that one or more plastic parts have broken, particularly if it fell and landed with pressure on that key.

Most of the keyboard manufacturers have parts departments that can supply just the part of the keyboard you need if you can specify exactly what you want.

Keys 7 and 8 from the bass side are lower than

In Casio Chord mode, the bottom keys up to the second F plays Bass Chords. The Keyboard is just putting the keys you play back into bass when you get up that high. If you read along the plastic edge above where they keys come out of the keyboard, it shows you where the Chord keys end and the Keyboard begins. If you want use of all the Octaves, slide the power switch to the first setting (normal).

The last two keys on the right side do not work

Probably something has come loose inside if everything else is normal.

Disassemble the device carefully. Look for cables or wires that may be partially or totally disconnected. If there are connectors, "reseat" the connectors. (Take them apart, put them back together firmly but not too firmly.)

If there is still a problem and you have a meter and are able to operate the keyboard with the unit open, you can compare voltage readings of those keys with nearby keys at any points you can find related to the keys. Compare with both keys up and keys down.

On some keyboards, you can bridge the switch contacts with an unbent paper clip to make a connection as though a key had been pressed. If you are comfortable with this and if doing that makes those keys play, then you have a mechanical problem related to the keys. Check for snapped plastic, etc.

From left hand side 10 keys not working

You might check settings first. The keyboard might be set to a mode where those keys have some function besides notes. Try a master reset and see if hings start working.

If it was working and now those keys don't, a fault has probably developed. There may be problems with connections to the keyboard, or there's been a component failure.

Sometimes getting into these things and accessing the keyboard is a challenge, and it's possible to do more harm than good. If it needs repair, you're probably better off taking the keyboard to a musician's store in your area and asking them to give you an estimate for the work (or to recommend a servicer if they don't do the work themselves).
