SOURCE: i need to know what driver i need to download and

The keyboard should stand alone and NOT require any driver. Drivers are for PC's,

Now if you are trying to connect the keyboard to a PC, then that is a different story. You did not mention that.

For tying a keyboard into a PC there are both USB and MIDI connections. You haven't mentioned using either.

When talking to a keyboard you will need music editing software, not a driver. That software you purchase SHOULD have what you need as part of it. There are also editors for the parameters in the keyboard. MOST of that software has to be purchased, although you sometimes can find shareware. Some can be quite expensive.

SOURCE: no display light on my casio ctk 496 every thing else works

Sorry, but many of the low end keyboards do NOT have backlights. This is especially true of those that have the capability of running off batteries like the CTK-496.

The display in this is a reflectance type that needs ambient lighting to view.

Problem with casio CTK-691 keyboard

"can I do it my self or should I go to a professional to get it repaired"?
Get it repaired by a professional. Casio gives long warranty (5 years in Australia). Mine took weeks for Casio Service to repair. Many boards had to be changed.

A friend of mine has a Casio keyboard CTK-691 which is not functioning. He asked me for help. I have another friend who is a radio repairman (professional). He has found out that the IC with position...

Here is a schematic for a CTK680... might be close to your CTK681...

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

Assuming this is the correct schematic, IC12 is shown as a TC750BF which is an open collector driver for the MIDI. If this part is bad, the MIDI output drive signal to an external device will not work. Without an external device connected, the output of this chip WILL NOT change as it is an open-collector driver and without the pull-up of the external device the output will remain at zero... so if the tech is testing this particular part AND the symptom is NOT that the MIDI signal to an external device is not working, then he is on the WRONG TRACK. Often radio repairmen do not understand logic chips and their variations.
