Hi All

We are going to dinner at my son's on Sunday and I will try the heat treatment, but my daughter-in-law does not want me to start repairs yet as the one of the grandchildren is practising for a piano exam so work will come to a halt for a while.

I will try the heat & freeze treatment on Sunday and also look at the electrolytic's for leakage.

I rang Yamaha yesterday and was pleasantly surprised at how helpful they were, they told me that the "avenue" that I have been advised to go down by other Forum member's was the same as their advise, they also said that major item's such as replacement board's were no longer available

Thank you for everyone's input, I will let you know as I progress

Bill
