I sent a letter to Roger Linn
he replied "I’m sorry to report that I haven’t thought about that old product in over 25 years, and even back then I didn’t do the non-creative parts of the hardware design nor did I ever deal with the service issues, so I wouldn’t know what to tell you. However, perhaps www.vstservice.com
in Los Angeles could help you because they were formerly Akai’s U.S. service center. "
Best of luck to you,
I sent a letter to www.vstservice.com
They replied - "Try to reseat all the internal connections – mainly the grey ribbon cable from the top half (operation board) to the bottom half (CPU Board) of the MPC.. also reseat the pad sensor membrane to the connector…."
I Tried to reseat all the internal connections! And Works Fine during 2 days!
thank you all !!!
love you guys!
