Test modes, English
- 31: CC sledge pos opto error.
Microprocessor 35IC2 cannot register pulses from 9PE1.
- 32: CC sledge calib switch error.
Microprocessor 35IC2 cannot register the signal REF. POS from the end stop
detector at pin 20.
This error also occurs if the tacho system is not working.
- 33: CC clamp pos error.
The clamper cannot go to the desired position. The reason may be that it is locked
or that there it is an error on PCB22, clamper position, or that the motor driver is
defective.
- 38: CC current sense error.
35IC2 pin 35 registers that the sledge uses too much current. The reason may be
that the sledge is blocked or that the sledge control is defective.
- 39: CC disc detect error.
The disk detector is not operating. Carry out test mode 71 to test the circuit.
- 40: CC sat sense error.
35IC2 pin 37 registers that the sledge uses too much current. The reason may be
that the sledge is blocked or that the sledge control is defective.
- 41: CC sledge blocked error.
The sledge is blocked, or the power supply to the sledge control may be too low.
- 42: Finger protection is out of operation.
The fi nger protection circuit is out of operation. Use test mode 71 during
troubleshooting.
PLT: Lid errors.
- 17: CC info plate pos error.
Position error. The lid may be blocked, the lid motor may be defective, or the
optocouplers 37PE1 and 37PE2 may be defective.
- 37: CC door pos error / CC plate pos error.
(Occurs during test mode 71 only) Position error. The lid may be blocked, the lid
motor may be defective, or the optocouplers 37PE1 and 37PE2 may be defective.
APS: Autoposition errors.
- 10: CC info P bit not found error
P bit has not been detected. If a CD-I Ready disc for example has been played back
at some point or if there is an error in the detection circuit. The error has been
detected at pin 11 of 35IC2.
- 11: CC info too many P bits.
Too many P bits have bin detected. May be caused by scratches in the disk.
- 12: CC info TTM opto adjusted.
Information that the turntable tacho has been adjusted. Data in EEPROM has been
lost.
- 14: CC info TTM pos count error.
An error has occurred in connection with scanning of the turntable motor
position. The position is not stored in EEPROM. Optocoupler / tacho may be
defective.
- 15: CC info TTM timeout error.
It has taken more than 5 seconds to carry out autopositioning. The turntable
motor driver may be defective.
- 18: CC info TTM pos opto error.
It has not been possible to make a correct adjustment of the autopositioning
circuit. The optocoupler circuit may be defective.
- 19: CC info TTM ref opto error.
The signal ROUND REF from PCB31 IR tacho clamper RX is missing.
