Default Logix 3000 DVD player - "No Disc" problem

I have the above captioned DVD player, recently bought used. It seems
to have a problem reading DVDs (at the moment I only have two).
Occasionally it will read the disc, but more often than not it gives
the "No Disc" error message. Audio CDs seem to be fine.

My first question is: is it more likely that the DVDs have degraded
or that the DVD player has?

My second question is: having looked inside the box, what I see
appears to be a standard computer DVD drive connected to the power
supply side with a standard computer power supply cable and to the
other side with a standard 40-pin IDE cable. The only notable
difference is that there is no Audio cable evident. If the DVD player
rather than my DVDs turn out to be the problem, would it be worth
trying to use a computer DVD drive in place of what's there now?

Any suggestions welcomed.

Nope. It's likely the player.

Your player likely uses a dual laser/single lens configuration for the optical
pickup. One laser is optimized for DVDs while the other is optimized for CDs.

For a DVD player, it is fairly safe to assume that it will be mostly used to
play DVDs, which means that the DVD laser gets the wear from use.

Eventually, the laser will start to become marginal and will no longer emit
light at the required efficiency like it once did. This problem is much more
prevalent on "economy" DVD players like the brand you mentioned.

My second question is: having looked inside the box, what I see
appears to be a standard computer DVD drive connected to the power
supply side with a standard computer power supply cable and to the
other side with a standard 40-pin IDE cable.


In this case, it is most certainly possible that your DVD player may be able to
accomodate an IDE standard DVD-ROM drive from almost any manufacturer.

It may be worth getting a DVD-ROM drive if you can find a decent drive at a
reasonable price. - Reinhart

wouldnt it be nice if more things were standardized and interchangeable as
such, replacement parts would be easy to find
