You have an internal mechanical switch/sensor which failed and will need replacement.The reason it is giving this message because the sensor might have been stuck in a position when it was damaged. And also along with it some parts(semiconductors and capacitors needs to replaced too)need some checking too.

If press eject button,it's showing LOCKED.what can i do?

You may try power resetting the unit and check if it helps. To power reset, turn OFF the DVD player and unplug the power cord from the electrical outlet for 30 seconds. Plug the power cord back into the electrical outlet and turn the player ON. Attempt to open the disc tray.

Depending on the model number of your DVD player, simultaneously press the POWER + STOP + EJECT buttons. If the disc tray still does not open, simultaneously press the DISC1 + STOP + EJECT buttons.
NOTE: This step may not apply to all models as DISC1 is not available on all DVD players.

If this does not work and if the DVD player has DISPLAY and PREV buttons, press and hold the DISPLAY+PREV buttons for two seconds to unlock the drawer.

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...


This is a DVD/MIDI Player with a "no disc error" upon loading any disc that played before...
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...
I've suspected the spindle motor was already bad but still to be confirm...



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!

2. Close the disc tray
3. Switch Off Player and Unplug from mains wait minimum 30 seconds - this resets the memory, and RAM of the DVD/BlueRay
4. Make sure your TV is on as usual, and Reconnect to mains
5. Turn on your DVD/Blueray player with remote and wait for the "no disc" message to appear
6. PS! As quickly as possible, using your controller press - ENTER 8 4 2 6 9 ENTER
7. You have been successful when a blue box appears in the top left-hand side of the TV Screen, displaying the message "DVD Region Free"

You may have to attempt the "ENTER 8 4 2 6 9 ENTER" sequence several times before you get the Region Free message if you're not quick enough.

The disc has appeared to stop rotating. The info window continously says "reading".

DVD/CD Read/Write process: 1. The tray or carriage places the disc into the spindle or motor. 2. The spindle motor locks into place to prepare motor to spin - the disc is in free space and does not touch anything except the spindle motor. 3. The laser assembly moves into home position and attempts to focus on the disc by emitting infrared light to disc. 4. If a disc is present, the light should reflect back to the laser lens as the lens attempts to focus on the light - you will notice the lens moving up and down to focus. The lens should NOT touch anything. 5. Upon a successful focus, the spindle motor spins. 6. Data is read and sent to a buffer for decoding. 7. Success.

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.

"No Disc"

Here are a couple solutions:

How To Recalibrate DVD Player


For those that are having the skiping up and unreadable disk problems try the following calabration. I did it last night and now my DVD's are much clearer and I'm hoping the skiping problem is gone.

For those that have the lip sync problem Sony should cover this for no charge, you just need to push them a little. This is a firmware update, have a look at the other posts at this web site to find the firmware revision that you need.

Make sure that the DVD player is turned OFF and in the stand-by mode with the little red LED glowing above the on/off button.
To enter the service mode/test mode, press Title, Clear, and Power on the remote.
This will produce the following menu:
Test Mode Menu
0. Syscon Diagnosis
1. Drive Auto Adjustment
2. Drive Manual Operation
3. Mecha Aging
4. Emergency History
5. Version Information
6. Video Level Adjustment

Exit: POWER Key
What each item does;
Syscon Diagnosis = Leave this for service technicians.
Drive Auto Adjustment = Automatically calibrates DVDs and CDs.
Drive Manual Operation = Manually calibrates DVDs and CDs with prompts for permission to skip, execute and/or proceed after each adjustment is made or skipped. Offers a fascinating look at all of the many adjustments made, but this method is time consuming.
Mecha Aging = Allows auto repeat mode for testing purposes.
Emergency History = Shows the number of hours on your machine.
Version Information = Shows firmware version.
Video Level Adjustment = Test pattern.
Press #1 (Drive Auto Adjustment) on the remote and the following menu will appear:
Drive Auto Adjustment
0. All
2. CD

Press #1 (DVD-SL) on the remote and insert a Single Layer DVD when the drawer opens.
Even though you may be interested in calibrating only a dual-layer DVD, do not skip the single-layer calibration procedure. For some reason, the player prefers to first calibrate a single-layer DVD before proceeding to a dual-layer disc. Error messages may result if the single-layer calibration procedure is not performed first.
Press the enter key and the machine will begin to calibrate all of the playback features. When calibration is completed, follow the onscreen instructions to return to the above menu.
When the Drive Auto Adjustment menu returns, press #3 (DVD-DL) on the remote and insert a Dual Layer DVD when the drawer opens. Follow the instructions as noted above.
When calibration is completed, follow the onscreen instructions to exit from the Test Mode Menu. Now you can turn the player back on and try your dual layer discs to see if the layer change has improved.
If you have any concerns about trying this service mode calibration, leave it for an authorized service facility
Other solutions:

1. To reach this test menu on a DAV-S300, press and hold the "STOP" and "Muting" button on your DVD Player (not remote) and turn the volume nob clockwise about 180 degrees. You will see a flicker. A blue test screen will appear, allowing you to calibrate your DVD. Please note that if you have no technical experience, messing around in this menu can cause serious damage to your DVD. The calibration option will be under: option 1, Disc Drive Auto Adjustment (or words to that effect). Be sure to calibrate a single-layer disc first, then dual layer -- you need to calibrate both types. Good luck.

In order for the STOP + MUTE + VOLUME sequence to work, your player must be ON, but have no disc present. You need to empty the tray, power off the S300 and power it back on. Wait until the INSERT DISC/NO DISC prompt appears. Then try the SMV sequence. And you must use the buttons on the unit, NOT on the remote, to enter the service menu. Once in the menu, use your remote to select the auto calibration menu and go from there.

2. This will fix the C 13:00 problem on any Sony DVD player.
With the machine turned off on standby, press the following 3 buttons
on the handset, in order: TITLE CLEAR POWER. The Diagnostic Start menu will come up on the TV. Select the appropriate button number for "auto adjust". The
machine basically does it all. It asks you to select either a single
layer or double layer disc (whatever your offending disc is.) Ejects
the tray, asks you to put your disc in and then calibrates it. (It's
over in about half a second... painless) Just follow the prompts on the screen

DVD playback problems

Did you buy these DVD's out of the country? Are they burned? did you pick English and the United States of America when you set up the dvd player? Try unplugging the player for an hour, plugging in and resetting everything up
