Keyboard problems question?

[Ian J. Evans]

I own a CVP 209 with not many hours use, when I use it it is mostly in the piano mode.

I have not had any keyboard problems which may be due to the limited use, or it may be in a series number range that does not have any problems.

I would be interested to know what series number range have had problems...?

Would those of you that have had problems corrected be willing to publish the numbers on this forum so that others may have a chance to check their instruments and be forewarned...?

Thanks in advance, Ian
