HCD-ZX10D SECTION 1 SERVICING NOTES
NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT The laser diode in the optical pick-up block may suffer electrostatic break-down because of the potential difference generated by the charged electrostatic load, etc. on clothing and the human body. During repair, pay attention to electrostatic break-down and also use the procedure in the printed matter which is included in the repair parts. The flexible board is easily damaged and should be handled with care. NOTES ON LASER DIODE EMISSION CHECK The laser beam on this model is concentrated so as to be focused on the disc reflective surface by the objective lens in the optical pickup block. Therefore, when checking the laser diode emission, observe from more than 30 cm away from the objective lens. UNLEADED SOLDER Boards requiring use of unleaded solder are printed with the leadfree mark (LF) indicating the solder contains no lead. (Caution: Some printed circuit boards may not come printed with the lead free mark due to their particular size)

Ver. 1.1

NOTE OF REPLACING THE DMB07 BOARD When replacing the DMB07 board, since the adjustment value is not set up correctly, "Drive Auto Adjustment" can't be performed. In this case, initialize memory in the following procedures. Procedure: 1. Set the test mode. (See page 18) 2. Press the [2] key on the remote commander, and set the "DRIVE MANUAL OPERATION". (See page 21) 3. Press the [6] key on the remote commander, and set the "2-6, Memory Check". (See page 23) 4. Press the [CLEAR] key on the remote commander, and initialize Memory.

MODEL IDENTIFICATION Back Panel

PART No.

: LEAD FREE MARK Unleaded solder has the following characteristics. Unleaded solder melts at a temperature about 40 C higher than ordinary solder. Ordinary soldering irons can be used but the iron tip has to be applied to the solder joint for a slightly longer time. Soldering irons using a temperature regulator should be set to about 350 C. Caution: The printed pattern (copper foil) may peel away if the heated tip is applied for too long, so be careful! Strong viscosity Unleaded solder is more viscou-s (sticky, less prone to flow) than ordinary solder so use caution not to let solder bridges occur such as on IC pins, etc. Usable with ordinary solder It is best to use only unleaded solder but unleaded solder may also be added to ordinary solder. RELEASING THE DISC TRAY LOCK The disc tray lock function for the antitheft of an demonstration disc in the store is equipped. Releasing Procedure : 1. Press ?/1 button to turn the power on. 2. Press the [FUNCTION] button to select the "DVD". 3. Press two buttons of x (DVD) and Z OPEN/CLOSE simultaneously and hold down until "UNLOCKED" displayed on the fluorescent indicator tube (around 5 seconds).
Note: When "LOCKED" is displayed, the tray lock is not released by turning power on/off with the ?/1 button.

DVD SECTION
About the dicision to pass or fail of the optical pick-up block, refer to "DICISION TO PASS OR FAIL OF THE OPTICAL PICK-UP BLOCK" (Refer to page 6 in SERVICING NOTES) Precaution 1. DVD block is basically designed to operate without adjustment. Therefore, check each item in order given. 2. Use DVD reference disc unless othermise indicated. [DVD reference disc] TDV-520CSO (DVD-SL) : PART No. J-2501-236-A LUV-P01 (CD) : PART No. 4-999-032-01 TDV-540C (DVD-DL) : PART No. J-2501-235-A Note: Do not use exiting test disc for DVD. 3. Use an oscilloscope with more than 10MW impedance. 4. Clean the object lens by an applicator with neutral detergent when the signal level is low than specified value with the following checks. AUTO SERVO ADJUSTMENT After parts related to the servo circuit (RF amplifier (IC001), DSP (IC509), motor driver (IC501), EEPROM (IC903) so on) are replaced, re-adjusting the servo circuit is necessary. Select "ALL" at "1. Drive Auto Adjustment" (Refer to page 19 in TEST MODE) and adjust DVD-SL (single layer), CD and DVD-DL (dual layer). VIDEO LEVEL CHECK Purpose: This adjustment is made to satisfy the NTSC standard, and if not adjusted correctly, the brightness will be too large or small.
