Fantom G6 - flat cables serial numbers?

[rackko1986]

Hello to everyone..I need to buy new flat cables that connects key conntact board with mother board.. There are two flat cables, coming from keys board, leading to the motherboard.. Original ones are demaged, and i need new cables. I found local dealer for Roland in my country, however they need serial number of cables, or catalog number of those flat cables, so they can make new order from Roland factory. I tryed to fing that serial numbers, but no succeed, so can you help me with that? Also i need serial numbers or catalog numbers for flat cables for screen(display) for fantom G6..Maybe if someone has service manuel , that also would help, i guess..Thanks, regards.
