DVD spindle motor replacements.

Guest
I have two DVD players in my shop. One is a Mitsubishi DD-6000, the other is a
Toshiba SD-1300A. They both have bad spindle motors caused by flimsy brushes.
One of the motors has a direct short across the dc input, the other one had
very low torque. Both manufacturers make you buy the entire assembly, laser,
etc., in order to get a new spindle motor. This assembly is over $110. As you
can see by the photo of these motors:
http://www.pbase.com/image/25340423/ they seem very similar. I tried removing
the motor casing to repair it but it is nearly impossible to do so without
deforming the metal enclosure. Does anyone know of a generic type replacement
for this type of motor. It doesn't seem much more complicated than a regular cd
spindle motor except that there is an extra optical sensing device to regulate
speed.

Thanks for your reply.

Many small motors like this have small slits at the bottom. You can spray
cleaner/lubricant into the slits, aimed at the brushes, while turning the
motor. Use compressed air to blow out debris and excess lubricant. Repeat
til short cleared. Very effective, fixed lots of cd motors this way over the
years, only ever had 1 re-do.
You can even connect a variable dc supply to the motor, run it at a given
speed, spray the cleaner at the brushes and really notice the motor "taking
off" when the short clears.
The brushes pick up carbon from sparking, which shorts out eventually. I
_think_ a silicon based lubricant will prevent future carbonization.

While searching Google for spindle motors, I found this very interesting review
of Toshiba DVD players and their expected life span.

Read the review - sounds like even worse junk than I'm used to.

I can supply you wit your hard to find numbers. I salvage those CD
roms that are not sold or display models. Motors are like new.
I sell single item at reasonable costs.

Hi there,

I don't think I need those motors any more as I posted that message more
than nine years ago. (-:

I have successfully removed the casing and reassembled motors like the one in the photo successfully. It requires patience. You may try Mark D. Zacharias procedure first, sounds good.

LOL! In an age of $70 blue ray players, I was wondering who was repairing any DVDs anymore!

I found a blu-ray player on the sidewalk three weeks ago, when everyone

was moving. The front panel of the drawer was missing, as if a disc had
gotten stuck and they'd tried to pry open the drawer. I plug it in, the
display says "power on" and then it seems to turn off. But hooking it up,
it plays a DVD fine, there's a feature to turn off the display. I have to
get a blu-ray movie to try that, but it seems fine.

No remote, which perhaps is the issue. A lot of these things need the
original remote to do much. And this one is relatively fancy, has an
ethernet port so it can do internet things. Apparently one can hook up a
USB keyboard, I hope but doubt that that would mean I can control it from
the keyboard.

And like my tv set, and like my TomTom One $10 garage sale GPS, this too
uses LInux.

An economical way I have found to use things like these when the original remote is missing is to buy two universal remotes at least one with learning capability. They are cheap. It is very likely there are some codes in the universal remote that will work most functions but with keys incorrectly mapped to buttons. It is unlikely you will find a working code with keys correctly mapped, at least with todays cheap no name brand devices where all of them seem to share a manufacturer but have different remote key codes.
To search for a code keep the device turned on while using the remote search funcion, as soon as you see any response, stop and try all buttons, surely many of them will trigger different responses.
At this point use the learning remote to map them to the correct key according to the observed response. After a while you end with a fully functional remote for that device.
