Philips DVDR-1000 problems

    I'm working on two Philips DVDR-1000 DVD recorders that have problems.
    One will play and record on a DVD+RW, but will not play pressed DVDs,
    or DVD-R. The other won't recognize any DVDs. Both play CDs and
    CD-RWs fine. I've already tried cleaning. I would think a weak laser
    would cause playback of DVD+RWs and recording to stop before pressed
    DVDs.

    Are there any service bulletins, or known common problem with this
    model? I've been searching the web for information and it seems that
    a lot of them had problems reading discs early on, but were fixed
    under warranty. Is there a service adjustment, or diagnostics mode?
    These recorders don't look like they were used much, so I'm hoping the
    optical pickups are still good.

  3. M (very limited) experience with dvd recorders is that the entire mech and
    it's circuit board would be replaced if under warranty, otherwise it just
    doesn't get fixed, as individual parts aren't sold, only the complete ass'y.
    Over 400.00 typically just for the part. Although I'm not a Philips
    servicer, this is very consistent with Philips' approach to cd / dvd
    service.

    Replacing the entire optical deck is what I'm trying to avoid. It
    would certainly not be worth it on such an old recorder when new ones
    cost under $400. The symptoms are strange. I have 4 recorders which
    I'm trying to combine into as many good ones as possible. Two will
    record on a +RW, but are unable to read the discs most of the time.
    Sometimes they will read a +RW, but never a +R, or pressed disc. One
    won't read, or write on any DVD and one seems to work fine. By
    swapping parts among the 3 with problems I've found that it seems to
    be related to the optical pickups. I'm hoping there's some type of
    alignment that can be done in the field. One sometimes displays "DB
    7FC5F394" in the display after trying to read the disc. The recorders
    have clearly not been used much and the optics are spotlessly clean.
    I've updated the firmware in all of them.

    After doing some more research, it seems that these symptoms are very
    common on Philips DVD recorders, particularly this model. Lots of
    people have reported failure of DVD+R playback and recording, followed
    by pressed DVDs and finally recording and +RWs. They all said it was
    fixed by Philips replacing the entire optical deck under warranty
    (sometimes several times), or that Philips gave them a refund, or
    replaced with a different model.

    I would love to know what's really causing these failures. It can't
    be the laser diode itself because it would be driven the hardest while
    recording. A failure of the tracking / focusing electronics or optics
    would affect CD playback. I suspect either a problem with the photo
    diode array, or the plastic lens that sits directly in front of the
    photo diode. The rest of the DVD optics is glass and securely glued
    in place.

    The build quality is excellent, but there's obviously a fatal flaw in
    the design of the optical pickup, or one of its components. That's
    typical Philips quality for you.
