Question about Sharper Image MC502 System

Open Question

Unknown Disc Format

When I load either a DVD or a CD, the system will try to load but then after about 2 minutes the message "Unkown Disc Format" appears on the TV screen. This even occurs when I put in a cleaning disc. The other features of the system work fine (ie the tuner). I haven't used the system in about 5 months but it has remained plugged in and set up during that time. Prior to now I have never had the problem. Thanks for the Help.

Unsupported format

I have the same problem. When I put in a dvd it tries to read it and then comes back unupported format. What does this mean and why won't it read the dvd?

Before you attempt to repair your DVD Player yourself, make sure that you have necessary tools and test instruments like philips screw drivers, multimeter, soldering iron, soldering lead, soldering pump, etc...

Watch this VIDEO
First I've loaded it with disc and observe the movement of the optical lens and the spindle motor. First thing I've noticed that the spindle motor didn't oscillate upon spinning and it's spin slowly unlike the normal RPM...

Unscrew the disc holder plate from the assembly to keep away the magnet touching the spindle motor, this may affect the reading and spinning of the motor upon testing with the multimeter.


This is how it looks like after removing the disc plate holder in the assembly. Spindle motor is secured with 2 small screws in the lens assembly.
Pull-out the connectors from the main board to see the underside of the tray.


You may test the spindle motor with your multimeter set in resistance measurement (ohms X1) even connected to the small board.
Bad motor will read either less than 5ohms(shorted winding) or infinity (open winding) and will not spin.
Good motor will read more than 50 ohms(depends the size) and will spin upon testing. Watch this VIDEO.



Onced you've confirmed that the motor was already faulty, unscrew it from the lens assembly.


Replaced the spindle motor with new one. Before you install the new motor make sure that the clearance of the disc holder is the same as the old one. Compare first the clearance because if it is to high the optical lens will not read the disc same if it is to low....

After replacing the motor re-insert all the connectors to the main board.
I've load same disc which does not read a while ago and observe what will happen. Observe the disc and the sound oscillation from the spindle motor in this VIDEO.

Hope that the above information, pictures, and video will help you fixing your DVD player yourself.
Thanks for visiting Fixya.
Have a nice day!

Bose lifestyle 48 says format unsupported for audio cds

Hi Johnxxlt,
According to Bose, the message that you have is due to dust in the system ....
They have offered 3 ways :-
Try cleaning the CD or DVD, as follows: 

  • Use a soft, dry, lint-free cloth to remove stains or fingerprints from the disc surface 

  • Wipe in straight movements from the center of the disc to the outside

  • Do not use any chemical cleaning products. They can damage the disc.
If the above will not fix the problem, you need to call them to repair the system.
I know its frustrating, However, we cannot play more with Bose as it might void the warranty if any.
Thanks for using Fixya.
Do rate the solution as "Fixya" if 100% satisfied.

Usually it helps a lot if you take off the upper case of the DVD player (7 screws) and search for the lens of the DVD/CD. Clean it with alcohol or terpentine or something like that and it will probably work afterwords. Good luck.

Unknown disc error

Either the lens of the DVD drive has got dirty, or the drive itself is faulty. Try cleaning the lens with a lens cleaning disk, if this does not work, return it for replacement (If it is still under warranty), or take it to a repair shop to have the DVD drive replaced.

Coby dvd-915, Shows "Disc Loading" goes to "No Disc"

Dear diniman

It looks like your CD is not being detected so it should be the problem with the lens. The clicking sound is nothing but the lens movement. So i suggest you to take it to a nearest electronics repair shop to get the player fixed or the lens changed. Please rate me...!!!

Not an Audio CD/Format Unsupported

Clean the CD and try again. Also, if DVD displays "not supported", call Bose and ask to recieve an update disc. These updates are released every 6 months. Document your remote control settings before loading the update as they may be erased by the update and will require re-entering settings after the update.
