My "New" Casiotone MT-40...is Broken

[Guest]

I purchased a Casiotone MT-40 at a thrift store knowing absolutely nothing about it. I came to find out it's a neat little gem that I should be happy to own. The sad part is that it doesn't work. The little on light comes on when I flip the switch, but there is no sound. Not even speaker fuzz or buzzing. It appears to be in good condition and I'd like to have it fixed. Is it possible to have a dinky little ancient keyboard repaired? Could I have it done through Casio?
