Alte gescannte Servicepläne sind oft doch etwas undeutlich . Stromlaufpläne werden auf mehrere DIN A4 Seiten aufgeteilt. Alles ziemlich umständlich und zeitaufwendig. Aber mit etwas Mühe geht alles.
<Example> Follow the below steps when E-1 is displayed. (Cause: Focus balance (FBC) is set beyond the limit.)
- Check if 1. the waveform or voltage of the focus servo circuit is correct, and 2. the optical pick-up returns to the normal state by exchanging the traverse deck.
Follow the below steps when E-4 is displayed. (Cause: Focus gain (FGC) is set beyond the limit.)
- Check if 1. the waveform or voltage of the focus servo circuit is correct, 2. the focus coil of the optical pick-up is correct (around 8 ohms), and 3. the optical pick-up returns to the normal state by exchanging the traverse deck.
Follow the below steps when E-F is displayed. (Cause: All adjustments (TGC, FGC, TBC, FBC) are set beyond the limit.)
- Check if 1. the optical pick-up returns to the normal state by exchanging the traverse deck, and 2. the waveform or voltage of the servo ICs are correct.
Note: It is not always necessary to exchange the traverse deck when an error message is displayed. Be sure to check if the circuit is defective or not before exchanging the traverse deck.
