The turntable fails to rotate or rotates at high speed.
Yes
Check the periphery of IC801 pins 23 to 27, pin 39 and pin 40,
IC802 pin 12 and pin 13, IC804 to BI803/CNS803.
The turntable rotates a little.
Yes
The spin driver circuit is normal.
Play operation is performed without disc.
•  Checking the spin system.
No
Yes
Check the IC801 pins 43 and 44, IC802 pins 3, 5, 7, 9 and 10.
Error
Yes
Check PDO waveform (Fig. 25).
•  Checking the VCO-PLL system
Play operation is performed when disc exits.
Yes
Although HF waveform is normal, TOC data cannot be read.
