ADJUSTMENT 6.1 CD ADJUSTMENT 1) Cautions on adjustments • In this product the single voltage (3.3V) is used for the regulator. The reference voltage is the REFO1 (1.65V) instead of the GND. If you should mistakenly short the REFO1 with the GND during adjustment, accurate voltage will not be obtained, and the servo’s misoperation will apply excessive shock to the pickup. To avoid such problems: a. Do not mix up the REFO1 with the GND when connecting the (-) probe of measuring instruments. Especially on an oscilloscope, avoid connecting the (-) probe for CH1 to the GND. b. In many cases, measuring instruments have the same potential as that for the (-) probe. Be sure to set the measuring instruments to the floating state. c. If you have mistakenly connected the REFO1 to the GND, turn off the regulator or the power immediately. • Before mounting and removing filters or leads for adjustment, be sure to turn off the regulator. • For stable circuit operation, keep the mechanism operating for about one minute or more after the regulator is turned on. • In the test mode, any software protections will not work. Avoid applying any mechanical or electrical shock to the mechanism during adjustment. • The RFI and RFO signals with a wide frequency range are easy to oscillate. When observing the signals, insert a resistor of 1k ohms in series. • The load and eject operation is not guarantied with the mechanism upside down. If the mechanism is blocked due to mistaken eject operation, reset the product or turn off and on the ACC to restore it. 2) Test mode This mode is used to adjust the CD mechanism module. • To enter the test mode. While pressing the 4 and 6 keys at the same time, reset. • To exit from the test mode. Turn off the ACC and back up. Notes: a. During ejection, do not press any other keys than the EJECT key until the loaded disc is ejected. b. If you have pressed the (→) key or (←) key during focus search, turn off the power immediately to protect the actuator from damage caused by the lens stuck. c. For the TR jump modes except 100TR, the track jump operation will continue even if the key is released. d. For the CRG move and 100TR jump modes, the tracking loop will be closed at the same time when the key is released. e. When the power is turned off and on, the jump mode is reset to the single TR (91), the RF amp gain is set to 0dB, and the auto-adjustment values are reset to the default settings. www. xiaoyu163. com QQ 376315150 9 9 2 8 9 4 2 9 8 TEL 13942296513 9 9 2 8 9 4 2 9 8 0 5 1 5 1 3 6 7 3 Q Q TEL 13942296513 QQ 376315150 892498299 TEL 13942296513 QQ 376315150 892498299 http://www.xiaoyu163.com DEH-2790MP/XN/ID 47 5 6 7 8 5 6 7 8 C D F A B E [BAND] [BAND] [BAND] [BAND] [BAND] Power On (T.Offset is adjusted) TRK00 MIN00 SEC SEC 00 [CD]or[SOURCE] Source On TRK MIN [4]+[6]+Reset or [4]+[6]+BU+ACC Test Mode In [3] [1] [1] Power On (T.Offset is not adjusted) TRK99 MIN99 SEC99 [2] [2] [2] [2] Power Off TRK MIN SEC Power Off TRK MIN SEC Power Off TRK MIN SEC Power Off TRK MIN SEC Focus Close S curve check T.Close and AGC Applicable servomechanism TRK91 MIN91 SEC91 [6] [1] [3] [6] [3] Focus Mode switching SPINDLE Speed switching RF AMP Gain switching TRK0xMIN0xSEC0x Tracking Servo Close TRK00 MIN00 SEC00 or TRK99 MIN99 SEC99 CRG- TRK00 MIN00 SEC00 or TRK99 MIN99 SEC99 [→] [←] [→] [←] [→] [←] CRG+ TRK00 MIN00 SEC00 or TRK99 MIN99 SEC99 Automatic adjustment switching TRK??

The PU unit in the CD mechanism module is adjusted on the production line to match the CD mechanism module and is thus the best adjusted PU unit for the CD mechanism module. Changing the PU unit is thus best considered as a last resort. However, if the PU unit must be changed, the grating should be checked using the procedure below. • Purpose : To check that the grating is within an acceptable range when the PU unit is changed. • Symptoms of Mal-adjustment : If the grating is off by a large amount symptoms such as being unable to close tracking, being unable to perform track search operations, or taking a long time for track searching. • Method : • Measuring Equipment • Measuring Points • Oscilloscope, Two L.P.F. • E, F, REFO1 • Disc • TCD-782 • Mode • TEST MODE • Checking Procedure 1. In test mode, load the disc and switch the 3V regulator on. 2. Using the → and ← buttons, move the PU unit to the innermost track. 3. Press key 3 to close focus, the display should read "91". Press key 2 to implement the tracking balance adjustment the display should now read "81". Press key 3. The display will change, returning to "81" on the fourth press. 4. As shown in the diagram above, monitor the LPF outputs using the oscilloscope and check that the phase difference is within 75° . Refer to the photographs supplied to determine the phase angle. 5. If the phase difference is determined to be greater than 75° try changing the PU unit to see if there is any improvement. If, after trying this a number of times, the grating angle does not become less than 75° then the mechanism should be judged to be at fault. • Note Because of eccentricity in the disc and a slight misalignment of the clamping center the grating waveform may be seen to "wobble" ( the phase difference changes as the disc rotates). The angle specified above indicates the average angle. • Hint Reloading the disc changes the clamp position and may decrease the "wobble". 100kΩ 390pF 100kΩ 390pF E VREF F VREF Xch Ych L.P.F. L.P.F.

The purpose is to reduce nonsense calls from users as well as to assist all related analysis and repair for defects at service station. (1) Basic Display Method 1) When CSMOD (CD mode area for system) is SERRORM, Error code will be written in DMIN (minutes area for display), DSEC (seconds area for display). The same data shall be written in DMIN and DSEC. DTNO is blank as usual. 2) Display Example of Head Unit The following is about LCD display ability. xx is Error number. 8 digits 6 digits 4 digits ERROR–xx ERR–xx E–xx (2) Error Code List No. Classification Contents Details • Cause 10 Electricity Carriage Home NG CRG can’t move to the inner. CRG can’t move from the inner. → HOME SW failure, CRG movement failure. 11 Electricity Focus Search NG Focus can’t be caught. → Back of Disc / Severe dirt and vibration. 23 Disc File Format NG Contents are stored in an incompatible file format. → The contents in a CD-ROM disc inserted are recorded in a file format other than ISO9660 Level-1 and 2. 22 Disc Impossible to play There is no playable MP3 or WMA file present in a disc. → No MP3 or WMA file exists in a CD-ROM disc inserted. 17 Electricity Setup NG AGC protection doesn’t work, out of Focus soon. → Scratch on Disc/Severe dirt and vibration. 12 Electricity Spindle Lock NG Not spindle, lock. Wrong subcode (can’t read). Subcode NG RF-amp NG → Defective Spindle. Scratch and dirt on Disc. Intense vibration. The appropriate gain of the RF amp cannot be obtained. → Defective spindle. → Blanc CD-R disc. Disc inserted upside down. → Scratched or dirty disc. Severe vibration. Abnormal CD signals. 30 Electricity Search Time Out Can’t reach the target address. → Defective CRG/tracking, or scratch on Disc. → All TRK Nos. In a disc inserted are specified as a track which should be skipped, in the track skip information. 44 Disc Impossible to play There is no playable TRK No. present in a disc. 50 Mecha Disc Load / Eject NG Disc loading/ejection cannot be complete. → Foreign objects entered into the mechanism. Disc caught in between during loading/ejection. A0 System Power NG Power supply (VD) isn’t connected to the ground. → Defective SW transistor. Abnormal power (failed connector) OR Err–xx Note : Error doesn’t display in mechanism only. (CD off causes mechanism off) If TOC can’t be read, error wouldn’t occur, but mechanism still continues its operation. The upper digits of error code is mainly classified by 3 kinds as follows: 1x: Setup related error, 3x: Search related error, Ax: Other errors. www. xiaoyu163. com QQ 376315150 9 9 2 8 9 4 2 9 8 TEL 13942296513 9 9 2 8 9 4 2 9 8 0 5 1 5 1 3 6 7 3 Q Q TEL 13942296513 QQ 376315150 892498299 TEL 13942296513 QQ 376315150 892498299 http://www.xiaoyu163.com DEH-2790MP/XN/ID 51 5 6 7 8 5 6 7 8 C D F A B E 6.4 SYSTEM MICROCOMPUTER TEST PROGRAM - PCL Output In the normal operation mode (with the detachable panel installed, the ACC switched ON, the standby mode cancelled), shift the TESTIN (Pin 15) terminal to H. The clock signal is output from the PCL terminal (Pin 14). The frequency of the clock signal is 786.432kHz that is one 16th of the fundamental frequency. The clock signal should be 786.432kHz ± 31.5Hz. If the clock signal is out of the range, the X'tal (X601) should be replaced with new one. www. xiaoyu163. com QQ 376315150 9 9 2 8 9 4 2 9 8 TEL 13942296513 9 9 2 8 9 4 2 9 8 0 5 1 5 1 3 6 7 3 Q Q TEL 13942296513 QQ 376315150 892498299 TEL 13942296513 QQ 376315150 892498299 http://www.xiaoyu163.com DEH-2790MP/XN/ID 52 1 2 3 4 1 2 3 4 C D F A B E 7.
