left and right analog audio. In the right position you get left and right analog audio and no
5.Be sure the video selector switch on the SD3006 is in the proper position when you check out the video outputs. In the left position you get composite and S video. In the right position you get component video.
6.If the color difference cables are reversed the picture information is present, but the color has a blue tint.
7.Putting the luminance cable in the wrong connector causes a very visible sync problem.
8.A dirty disc can cause playability problems,
.so be sure the disc is clean. Use a soft cloth to clean a disc. Refer to the cleaning instruc- tions in the service manual.
Power Supply Checks
1.Push the power button and see if the red power led comes on.
2.Check the dc voltages on pins 2, 3, 4, 5, 6, 7, 8, 12, 13, and 14 of CN801.
3.If any of these voltages are improper or missing, or the power LED does not come on, unplug the power supply from the main board and jumper pins 2 and 3 on CN801.

4.Recheck the dc voltages on pins 2, 3, 4, 5, 6, 7, 8, 12, 13, and 14.
5.If the voltages are still improper or missing there is a problem with the power supply. However, if the voltages are normal the power supply is alright, and there is most likely a problem on the main board or 1 of the other boards that is loading down the power supply.
6.For a loading problem on a board other than the main board, remove AC power and reconnect the power supply to the main board. Remove the connector to the front panel and apply AC power. Check the voltages supplied to the front board. Repeat this process for each board, and when the board causing the problem is disconnected the power supply voltages should return to normal.
Front Panel Checks
1.Using a meter check pin 2 for the ever 5 volts, pin 8 for the
2.Using a scope, check the front panel reset signal at pin 1 of CN602 when AC is applied to the player. The signal goes high when power is applied to the player.
3.To check the communications between the main board and the front panel, connect channel 1 of the scope to the FSTBX signal on pin 7 of CN602. Communications be-
