Question about Sony DAV-S300 System
This is much more simple test than that. I assume that the unit only has issues with a DVD. Insert a CD. If that plays, you have an Optical Pickup(laser) that's bad. The servo system and audio path basically follow the same path, to a point. The wavelength of DVD and CD are different, therefore, the Optical Pickup, has two lasers in one unit. Most likely, you are not using CDs as much as DVDs. If the CDs play, but not the DVDs, 90% chance, the pickup is bad. There are really no adjustments in CDs or DVD players anymore. I was an Authorized Service Center for Sony. The CDP-101, was the first player to hit the market. It had.....4 hours worth of adjustments! These products have come a long way in the last decade.
If you are interested in having your DVD player repaired, please contact me at my website, audioserviceclinic.com. You may contact me there. Thank you.

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.
HOW TO PERFORM THE CALIBRATION
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
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
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
