SECTION 1 SERVICING NOTES SAFETY CHECK-OUT After correcting the original service problem, perform the following safety check before releasing the set to the customer: Check the antenna terminals, metal trim, “metallized” knobs, screws, and all other exposed metal parts for AC leakage. Check leakage as described below. LEAKAGE The AC leakage from any exposed metal part to earth ground and from all exposed metal parts to any exposed metal part having a return to chassis, must not exceed 0.
CD-TEXT TEST DISC This unit is able to display the test data (character information) written in the CD on its fluorescent indicator tube. The CD-TEXT TEST DISC (TGCS-313:4-989-366-01) is used for checking the display. To check, perform the following procedure. Checking Method: 1. Turn ON the power, set the disc on the disc table with the side labeled as “test disc” as the right side, close the front cover, and chuck the disc. 2. Press the · button and play back the disc. 3.

SECTION 4 TEST MODE DISPLAY CHECK MODE With the power turned off (standby state), press the I/u button while pressing the P (pause) button. All FL segments and grids light up together with the · (play), P (pause), and standby LEDs. At the same time, the GROUP LEDs are scanned one by one. KEY AND FLUORESCENT DISPLAY TUBE CHECK MODE 1. Connect the test point (TP:AFADJ) of the MAIN board to the Ground, and insert the power plug to the outlet to set this mode.
Partial lighting 1 AGING MODE O A B C D E F G Partial lighting 2 O • Mode which repeatedly changes and plays back discs automatically in the unit. • It will repeat aging as long as no errors occur. • If an error occurs during aging, it will stop all servos, motors, etc. instantaneously, display the error number, and stop operations. However, the stopping conditions differ according to whether the unit is equipped with the “self-protection function during errors” described later.
Aging Method 1. Change the [COMMAND MODE] switch (S901) on set to [CD1]. 2. Turn ON the power of the unit. Open the front cover. 3. Press the [AGING START] button of the remote commander for aging mode (J-2501-123-A). 4. When the disc set mode is set, the · and P LEDs blink. 5. Rotate the JOG dial. The slits (No. 40, 80, 120, 160, 200) for setting the discs will come forward. Insert the discs into these slits. Do not set the discs in other slits. 6.
SECTION 5 MECHANICAL ADJUSTMENTS Perform the following steps before carrying out adjustments. 1. Turn ON the power of the unit, set disc to disc table No. 92, and perform chucking. 2. Turn OFF the power. 3. Remove the case. 4. While pressing the [STOP] button, turn ON the I/u button. The test mode is set. 5. The I/u button LED (STANDBY) starts blinking.
