The following items for the AV-21L31B/DPH model were changed from those of the
AV-21L31B
/PH model.
Therefore, this service manual describes mainly the items which differ from those of the
AV-21L31B
/PH & AV-25L31B/PH service manual.
But the difference of Main PWB ASS’Y is too much, so only Main PWB ASS’Y Electrical
Parts List, Circuit Diagrams and Pattern Diagrams are described every information.
For details other than those described in this manual, please refer the AV-21L31B
AV-25L31B
/PH service manual (No. 51905, Sep. 2001).
