Hi, for starters I apologize for my bad English. I wanted to has updated the firmware of my players (CDJ-350). I do not do it for the first time, with the first player all went well, waited to be displayed on the screen - completed, but when I repeated the same procedure on the second player, after completion and the player starts with this error E-8709 and nothing more!
I love to do with electronics and I downloaded the service book to introduce the structure and mode of operation and error codes.
Error I have E-8709 Communication between the Main CPU and Panel CPU has not been established. I ask ?? Should I change the MAIN ASSY DWX3105 because a fault in it? Could be a software error and is received after the update. Can re flashing internal ROM memory (IC101
DYW1792- / J)
The player is not under warranty, I called in the service of Pioneer from there told me I should change the board but the price is quite high and I ask here!
Waiting for response from engineers.
If someone is willing and able please help me!
I would be very grateful!
