Component Failure Determination on 700i

I don't think it's the MCU either. I'm going ahead to replace cables. Thanks for your help.

I forgot! At that time I replaced also twice the MCU PWB without success.

I'll give that a try before I go any further. Thank you so much.

Hi,

It could be the flat cables. I had one machine where I replaced twice the ROS. Finaly I replaced the cables and the problem was solved. Even the cables look good it could be defective. But it is possible to be an MCU issue.

I have gotten the following fault codes on 700i:

061-342, 061-236, 061-317

I have checked all flat cables and re-secured them. I figured the problem was the M/Y ROS but now on machine startup I'm getting:

061-319 and had one intermitant  061-329 indicating the problem is the C/K ROS. 

Now it seems more likely the problem is with the MCU PWB.  

What do you think? Is there something else I could be missing?
