Check the power supplies... beyond something pretty simple you won't have much of a chance of fixing if it is on the main board. Technics is really out of the business for the most part... they are a part of Panasonic. Expect to find voltages of +5 and +/-15 volts.

You can download a service manual for a KN6000 here and just MAYBE find enough simularity:

Scroll down to the "Get Manual" and click on it to start the download.

Power module out

First of all measure the power output of the mains adaptor. If this is working and the polarity is correct proceed.

Plug into keyboard with a lifting movement on the plug on the end of the cable - does it turn on? If not try pushing down on the plug. Does it turn on? IF in either of these positions the socket has broken away from the PCB - you will need to resolder or fit a new socket.

If still a problem then you would need to investigate the power input lines on the board inside. If you are not technically minded probably best let to a Yamaha service centre.

Hello, I have a big problem with my korg pa800 , yesterday I was on gig, and suddenly the whole keyboard in the middle of playing got the distortion on every sampled or fabric tone!!! I have tried...

It will require repair. I suspect by you description that the D-A convertor has failed. This is a chip that is far beyond a DIY project to change. Do further testing to make sure the power supply voltages are correct and that headphone output sounds the same problem.

Here is your service manual:

Scroll down to "get manual" and click to download the manual. IGNORE other download links.

Casiotone MT-220 keyboard power cord

I would inspect the unit for corrosion on battery terminals AND the power connector. The connector has a switch when a cord is plugged in, and if this switch doesn't work (they get bent) the unit will not work on batteries.
Best source of power adapters is often your local thrift store.
MATCH the voltage and whether it is AC or DC required AND the polarity if the pin is + or -.
Get one with enough current.

Casio CT-670 Tone Bank keyboard completely dead

How familiar are you with schematics? I've just found my CT-670, There where marker marks on the keys. I cleaned it up. I took it apart as one channels had no sound. I love this machine. I want to find a manual for it also schematics would be very helpful for me too.
I would suggest looking inside for burns on semiconductors. or loose soldering. I need to replace a chip that has no cross reference... that I've found yet... I think it's an amplifier but need to spend more time on it....
