First Generation Dvd Players - Sony DVP-S300 Training Manual

First Generation DVD
The first generation Sony DVD player consisted of two models, the DVP-
S3000 and the DVP-S7000. They housed separate laser assemblies to
play DVDs and CDs. Much of the video processing was done by discrete
medium size ICs. Failures across the country have been very low so
there is not much feedback history.

Repair Procedure
1. Check both video jacks for broken solder connections.
2. Press down on IC281 when the intermittent occurs. Resolder all the
pins if the condition responds to movement. Use flux on the pins to
prevent solder bridges and inspect the pins before powering the unit
on.
3. If the problem appears thermal, cool off the IC to see if the brightness
returns. Replace IC281.
