jayctoy,
Here is how you can check the Laser OutPut Level (LOP) of the lasers in the SA-10
Player needs to be fully OFF, not on standby, OFF. Everything after step 2 is done with the remote.
1. Enter Aging Mode from OFF, as stated above.
2. Press Open, Stop and ON simultaneously to enter Aging Mode.
The tray will open. Just press close on the remote to close the tray. No need to put in a disc.
3. Right click once and T21 laser check will show in the display window.
4. Press the play arrow and a number will be displayed. This is the cd laser LOP.
5. Right click again and T22 laser check will show.
6. Press the play arrow again and a number will be displayed. This is the sacd laser LOP.
7. Exit Aging Mode by pressing the OFF button on the front panel of the player.
The median LOP is 2100. The acceptable range is +- 50%, or 1000 to 3200.
When the LOP goes outside the acceptable range it is time to replace the laser.
The relevant number for you is the T22 number.
