    Faunc 18MC 916 DRAM Parity Error Recovery Help

    My mid/late 90's Mori Seiki SV50 just threw a 916 bomb on me. I have Parameter backups but have never inserted a card into the slot to back up whatever is available there. LED's on Main Control say RAM Parity error on Main CPU.

    I read to Restart with RESET and DELETE held in and start reloading Parameters, but is there anything else a guy should check first? Like Hardware issues for example? Fried boards etc.?

    Are these errors ever cleared by simply restarting?


    Here's a screen shot



    I have not yet shut down the control.

    A "ALL CLEAR' should not be needed.
    A DRAM parity error should be unrelated; if you can,. do a SRAM backup first. The DRAM module is likely the problem; it should be replaceable without losing data.
