Thanks, Jokeyman, will try this.

Brad and Joe - seems now Casio only gives 1 year warranty in India, not even the two i had earlier. Sounds very discriminatory, but seems that is how it is.

Thanks, Joe and Jokeyman.

Thanks, Joe. I am only trying to bypass some of the pricey dealers but stay within the network by going to some people I know. Will be good if you or Brad are able to help with the part number. Thanks again...

Further, Brad, is there a clear part / specification number here? Would be great if you can tell. Thanks.

Thanks, Brad, problem started at 2.5 years, its well over 3 years now. is there anyway to purchase pcb at reasonable prices in India. most local dealers demand exorbitant rates. I think the same motherboard works for multiple models, so should not be too expensive if wholesale dealers in India just courier it locally.

Dear Casio folks,

In 2.5 years my px-750 started showing problems in 3 keys / most piano sounds which is a strong jarring noise.Local dealers in India checked with stand-in pcb and it worked fine. Costs me almost 30% of piano price. Is there any other way to solve it like with a factory reset or something? Deeply disappointed...pls help. Thanks. 

Has anybody been able to solve the loud jarring sound on some keys in px-750 and the likes. I was told by a local dealer that its a motherboard issue but cost if replacement is very high. Has anyone tried something like a factory reset successfully? Thank you. 

Hello Emily, were you able to solve this problem. i have the same with my PX-750...Thanks.
