Fourth Generation DVD
The fourth generation DVD players consist of models DVP-S350, DVP-
S560, DVP-S560, DVP-S570, DVP-C660d and DVP-C670d.
Symptom 5:
Picture is distorted or there are Digital blocks that
appear during the movie.
Cause: A/V Decoder IC502
Repair procedure
In older DVD players this symptom is characteristic of a weak laser. In
this newer DVD player model, this picture-related symptom is caused by
the A/V Decoder defect. Much MPEG unscrambling now takes place in
one very complex A/V decoder instead of discrete parts, making it easier
to relate a picture problem to one part. Replace IC502.
