Recently, I am getting this different problem with my N 364.

If i press E3 key, then E3 sound along with E3flat key. which means both keys sound together. Same problem exists for B3 and C4 keys (both sounds together if i press any of this keys).

After 7 note, I will get this problem again in all 5 octave. I checked with contact rubber, it is fine. Hope the problem is in circuit board

Somebody please help me

I think it is a wiring problem.... check the cables going to the keyboards and check if some wires are making an unwanted connection with eachother.
