Hello, Rusty. Thanks for your response. Yes, I'm confident to try anything suggested, but not tonight as it's too late at night. Can I suggest you tell me, individually, step by step what to do and that I let you know how it's going as we progress? I'll need to carry out your suggestions when I can fit them in. Thanks again and I look forward to working with you. Tim
I'll give it a go as soon as I can get a can of compressed air and will let you know how it goes. Many thanks for your help so far. I'm impressed! Tim
I just thought I'd let you know how things are going. I tried the compressed air, but that didn't work, though it did blow out a lot of dust from inside; no bad thing. While doing this, I saw that something must have been spilt in the vicinity of the non-playing keys and also noticed that the circuit board had been affected. I decided therefore to go further than I had intended and took off the circuit board which seemed to have ancient blackcurrant juice on it. This was also on the keys. I gently cleaned the circuits with isopropyl alcohol and then tried it out. The keys worked! I'm now individually cleaning the keys, a time-consuming task but I'll keep at it over the next few days when I have the time . So far so good! I'll keep you informed and add my rating when I've finished. So far, I'm really, really pleased. Thanks so much.
I've finished cleaning the keys and the circuit boards. The top-range board also had something sticky on it and having cleaned that off, it seems to have helped the tuning. I'll be testing it fully over the next few days. All the keys are also working again, and...I managed to put everything back together again without too much difficulty. So thanks so much for you help. I really appreciate your help and advice and will be giving you the highest grade I can. Brilliant and quick service.
