E-8303
PLAYER ERROR (Abnormality in writing in the buffer)
• E830399: Abnormality in writing in the buffer
In theory, this error code means that buffering to the SDRAM (IC303) was impossible. However, a defective SDRAM may not be a
real cause, because the unit would freeze if the SDRAM were defective. This error code is generated by factors associated with the
reading accuracy of the servo motor of the CD player, such as a high error rate and subcode not read.
Player Measure the error rate in Player Operation mode
of Service mode. To which the cause is
attributed, disc or player, must be judged first.
For measuring, play back the lead-in point
indicated in the error code by listening the sound.
E-8304
MP3 DECODE ERROR (Abnormal decoding)
As this is a decoding error code for MP3 format, it is of no relevance to reading of data in CD-DA format, which does not need
decoding. As the MP3 decoding process precedes the process of writing in the buffer, this error code is associated with the process
that precedes the process with which E-8303 is associated. This code may also be indicated when the quality of the RF signal is
deteriorated.
Player Measure the error rate in Player Operation mode
of Service mode. To which the cause is
attributed, disc or player, must be judged first.
For measuring, play back the lead-in point
indicated in the error code by listening the sound.
E-8305
DATA FORMAT ERROR (Abnormal data format)
The CD is played back in a format other than MP3. Or the quality of the RF signal is deteriorated.
The data on this symptom are not stored in the internal memory.
z Check if the CD being played back is in MP3
format.
x Measure the error rate in Player Operation
Player
mode of Service mode. To which the cause is
attributed, disc or player, must be judged first.
For measuring, play back the lead-in point
indicated in the error code by listening the sound.
E-8709
COMMUNICATION ERROR
See "E8709" error.
