keyboard problem

[sunilsur]

I am having CT607 keyboard. when I play normal piano after switching on, after some time it gives different sounds like echo etc. Hence unable to practice.

The CT-607 is an old model, so it's possible that there's a problem with one or more electronic components which would cost more to have repaired than simply getting a new keyboard.

Are you using batteries to power it, or a power adapter? If you're using batteries, you might try using a fresh set of batteries to see if that helps.
