SIO ERROR
Details of Error
÷
TOC read was incorrect or could not be read properly.
÷
Fault occurred during rewriting of UTOC rewriting, and rewriting
could not be performed correctly.
÷
Inserted a disc but could not bring in FOCUS.
÷
The DRAM has become filled with music data, but they can not
be written (to the disc).
÷
After reading UTOC, total number of TNO and NAME characters
was 0.
÷
Focus execution error, etc. occurred due to shock during REC-
PLAY.
÷
UTOC read was correct but could not be rewrite it.
÷
The EEPROM data are incorrect.
÷
Never completes EJECT.
÷
Never moves HEAD UP.
÷
Never moves HEAD DOWN.
÷
The set microcomputer and MD mechanism microcomputer
are not communicating properly.
÷
It can't communicate with system control IC and MD mechanism
control IC.
Measure
÷
The TOC data recorded on the disc do not comply with
MD Standards, so try using another disc.
÷
The disc may be scratched or damaged, so try using
another disc.
÷
Scratch on disc. Replaced with other discs.
÷
Check if there are scratches, dusts, fingerprints, or black

÷
Check if there are scratches, dusts, fingerprints, or black
spots on disc. Check if disc fluctuates eccentrically or

÷
Record and check if disc is recordable.
÷
Check if there are scratches, dusts, fingerprints, or black
spots on disc. Check if disc fluctuates eccentrically or
moves up and down largely.
÷
Check to see if the recording head contact is correct or if
there are any disconnections between the board and the
recording head.
÷
Try doing a Preliminary Adjustment and a normal
Adjustment. If the problem still persists, replace the
EEPROM.
÷
Check if communication line with the MD mechanism
assy and connector is normal.
