Hi,

I have a m50 61. There seems to be noise when the global MFX and TFX are ON, and all the sounds including the piano come with a noise.


The noise completetly goes away with the TFX and MFX are off , but sounds are very plain and without any umph( :( ).

I had given the keyboard to the local dealer , and since it is out of warranty , they wont be able to help me out (????) . I found this underground person who fixes keyboards and he tells me the problem could be in one of the 2 ic part numbers .

1) v54c3256164vd17pc
2) Mb87m4080pb-ge1


Can someone help / suggest a way I can resolve this problem.

Can someone from Korg International help? (already called them to no avail)
