Hi everyone. Decided to go down to the basement and fire up my U-20 keyboard after many years. Yeah finally got some time. Well most of the keys didn't work to my surprise. Did some internet research and apparently this is a common problem. So I took the whole thing apart, took all the keys out and cleaned all the key contacts with denatured alcohol and a cotton swab. Put the whole thing back together and the right half of the keyboard works like new. The left half zero keys work. Ugggg. Anyone have any experience with these? Seems like a cable connection to me. I didn't manhandle it or anything. Was very careful with the ribbons. Thinking about taking it to a repair shop to see what they say.
Thanks.
Thanks.
