Hi, I' m new to the forum and hoping that someone will be able to point me in the right direction. I just bought a cheap KN5000, knowing that it had a problem but thought I might be able to repair it. I'll try to explain it as best as I can and hope it doesn't sound too confusing.
Everything works as normal from the Ab(3) above middle C to the top end of the keyboard. Here's what happens below that, starting from C(1). The first 4 keys, including the black ones, don't produce any sound whatsoever. When the next 4 are played in turn, they sound their own note plus the one 4 below. For example, when I play E(1), it also sounds C(1), F(1) also sounds C#(1) etc.. The next 4 keys don't produce any sound when pressed but the following four again sound, along with the four notes which didn't produce any sound by themselves.
So, there is a pattern where the first 4 notes don't produce sound by themselves but are played by the next four as a discordant chord. It keeps repeating until G3 is reached after which everything is normal.
The first thing I tried was to reset everything to factory settings. Then I upgraded the software from version 5 to 10. (I had some problems initially with the Floppy Disk Drive but it seemed to resolve itself). I've checked all the connections inside and found nothing obvious.
Can anyone suggest a possible solution ?
Thanks,
Al.
