Riso SF5350

[Khumz]

Hello....
I have a Riso SF5350 showing coming up with errors T98-7056 and T99-014. It is displaying half screen and it has changed from English to another language. First it displayed error T98-7056 and later changed to T99-014.
It doesn't initialize at all.
Any suggestions or ideas please.

Re: Riso SF5350

T98-7056: Machine has failed the communication between Main microcomputer and Panel microcomputer. There is a possibility that the Signal Wire Harness between the main-system PBC and Panel PCB has a problem. Switch power off/on.
T99-014: Sub microcomputer is detected to be physically damaged. Switch power off/on.

Get a manual. Good luck.
