5.4 ERROR AND WARNING MESSAGE
A

Error by backup failure
SYS B ac kUpERR

The system microcomputer abnormality with backup data (EEPROM)

The following conditions are some possibilities: 1. Communication line to the EEPROM (or flash ROM) could either be disconnected or short. 2. The EEPROM (or flash ROM) IC itself could be faulty.

Error due to Power abnormality (through Protect circuit) Warning due to Power abnormality (through Protect circuit)

1. Abnormality due to short or exceeding threshold of V+10, V+5, V+3R3, VFDP 2. Somewhere toward System micro-p, VDET line get grounded, shorted, or broke
DVD Protect

DVD related Power Abnormality error

1. Abnormality due to short or exceeding threshold of V+6R8, V+5V, V+3 2. Somewhere toward System micro-p, VDET line get grounded, shorted, or broke

Over current surge detect error

� On the next normal power up, and OC Error1 don�t happened again, then probably it is due to shorted of speakers terminal. � IF OC Error occurred again, probabe cause may be following: 1. Out of the 3 digital Amp IC (TAS5142DKD) in AMP Assy, some of them may be faulty. 2. Somewhere along the lines from above mentioned IC to speakers Terminals, lines get shorted. 3. Somewhere along the lines from above mentioned IC to Amp Micro-p, XSD line get shorted to GND, or broke. 4. VS+12 voltage is below (below 10 V) 5. (symptom not appearing again) Due to customer setting, the 2 end of the SP cable got shorted, and volume got raised. 6. (symptom not appearing again) due to customer setting, SP cable conducting part touches the player chasis.
OC Er ror2

Over current surge detect error

D

� On the next normal power up, and OC Error2 don�t happened again, then probably it is due to over volume while playing. � IF OC Error occurred again, probabe cause may be following: 1. Somewhere along the lines from power sensing circuit to Amp micro-p, PCONFIG line get shorted to power line or broke.
Over T em p

High temperature error

� On the next normal power up, and Overtemp don�t happened again, then there is no abnormality. (Possible to be just temporary rise of temperature, so lower the volume and try playing again.) � If Overtemp occurred again, possible symptom are as follow: 1. Out of the 3 digital Amp IC (TAS5142DKD) in AMP Assy, some of them may be faulty. 2. Somewhere along the lines from the above mentioned IC to Amp micro-p, XOTW line get shorted to GND. 3. Heat Sink is not installed properly (screw loss, forget to apply silicon grease, etc )
