It depends a lot on the manufacturer. Many modern service manuals for DVD
players, have little more than a block diagram, and some virtually
unreadable schematics. Others, such as Sony and even Daewoo, have good
schematics, layout diagrams, IC internals and pinouts, and use of internal
diagnostics notes. The days of " theory of operation " notes are long gone,
except perhaps with the likes of Bose, whose audio equipment manuals still
contain detailed descriptions of how the circuitry works. From a commercial
point of view, I tend to find these days that unless a problem on a DVD
player is a known one, or an obvious 10 minute fix like a power supply cap,
or a laser that's actually worth changing for its cost, then the things are
not worth fixing, so what's in the service manual is largely immaterial.
Can I ask that when you reply to replies, that you don't top post please ?
It works ok with e-mails where it's one on one, and each of you knows what
the other is replying to, but not so well on usenet, where a thread needs to
be followed in a logical order by many individuals. In this case, it's much
better that the new comments follow the last ones. A reply can always be
shortened by removing all of the replies above about say 3 up. Thanks.
