Thank you very much, Bernard! I understand that this harp comes with two year limited waranty by Lyon and Healty. However, she probably need to be shipped back to the States. I believe the cost is probably more than 50% of its price. I really am not sure this is the best thing to do. I emailed L&H and it seems there is no reply yet. I phone the local retailer but in my previous experience, there is usually no reply at all. There is very few harp technician in this 7 million population city. Thanks a lot for your help anyway! Regards, LAM
