My 8648d give me a 519 OUTPUT LF LEVEL CAL RESTORE FAILURE ERROR. My service manual does not list this error!! Does anyone know what this error is? Thanks
There is a failure in writing to RAM or reading data from the calibration ROM. You can try to rectify this by doing the A6 output board calibration. If this failure persists, you can replace the A3 motherboard which contains the RAM. Or, you can send this unit to the factory for repair, as it requires servicing.
