    SECTION 1 SERVICING NOTE JIG FOR CHECKING BD BOARD WAVEFORM The special jig (J-2501-149-A) is useful for checking the waveform of the BD board. The names of terminals and the checking items to be performed are shown as follows. GND : Ground I+3V : For measuring IOP (Check the deterioration of the optical pick-up laser) IOP : For measuring IOP (Check the deterioration of the optical pick-up laser) TEO : TRK error signal (Traverse adjustment)
  • Page 7 IOP DATA RECORDING AND DISPLAY WHEN OPTICAL PICK-UP AND NON-VOLATILE MEMORY (IC171 OF BD BOARD) ARE REPLACED The IOP value labeled on the optical pick-up can be recorded in the non-volatile memory. By recording the value, it will eliminate the need to look at the value on the label of the optical pick-up.
