This service manual was determinant to enable to fix my Alpine Amplifier. I am pleased with my purchase. For a 5 star rating I would like to see a higher resolution scan of the printed circuit board lay-out because the gray scale grafics was dificult to see. Also some schematic diagrams were scanned at a slight angle. Never the less, it had all information I needed to troubleshoot and service my equipment.
 ;
Complete manual, the good quality of reproduction allows enlarged print-out of the schematic diagram in the size it probably had in the original print edition and which is necessary for practical use.
;
The service manual was complete and the components on the drawings very good visible.
;
downloaded next day , manual is very helpful , fast and easy

This Service Manual was exactly what I needed to repair my Philips TV. The purchase was convenient and I received the manual at the same day I paid for it.
KDC-9020R/MP919/PSW9521/X759
TEST MODE
Security items
1. Forced power-ON mode (all models) Even when writing is permitted by the security function (mask key), Power-on can be set for a 30 minute period each time the reset key is pressed while holding down the Q key and [4/8] keys. After 30 minutes elapses, can only be restored by using reset. 2. How to register the security code for EEPROM (F/E) replacement (coded security models) (1) Enter the test mode. (See "1. How to enter the test mode") (2) Press the [4/8] key to enter the MENU MODE. (3) While "Security" is displayed, press and hold the Track up or down key for a second to enter the security registration mode. (4) Enter the code using the FM/AM/Track up/Track down keys. FM key: Increments the number. AM key: Decrements the number. Track up key: Moves the cursor to the right. Track down key: Moves the cursor to the left. (5) Hold down the Track up key for at least 3 seconds and the message, "RE-ENTER" appears, so once again enter the code according to Step 4 above. (6) Hold down the Track up key for at least 3 seconds, and the message, "APPROVED" appears. (7) Cancel test mode. (See, 2. How to cancel the test mode.) Note: All clear cannot be performed on the security code for this model. 3. Simple way to clear the security code (K type only) (1) During code request mode, press the Track Up key for at least 3 seconds while holding down the AUTO key. (---- will disappear) (2) Enter, "KCAR" with the remote controller as described below. (Same as on 01 model.) � Press the remote controller 5 key twice, and press the Track Up key. (Enters a "K") � Press the remote controller 2 key three times, and press the Track Up key. (Enters a "C") � Press the remote controller 2 key once, and press the Track Up key. (Enters an "A") � Press the remote controller 7 key twice, and press the Track Up key. (Enters an "R") (3) Security function is canceled and unit sets to All-Off mode. (4) Code request mode appears if a mistake was made in entering the numbers. 4. Method of writing the Mask key while the EEPROM is in the initial status (1) Enter the test mode. (See "1. How to enter the test mode") (2) Press the [4/8] key to enter the Mask key registration mode. "TRANSMIT1" should be displayed now. The display at this time should show "< >" in place of "[ ]". (3) Point the Mask key remote toward the light sensor, and press and hold its key for more than 0.5 second. (4) When "TRANSMIT2" is displayed, press and hold the key on the Mask key remote for more than 0.5 second again. The first and second counter codes are not compared at this time. (5) When "APPROVED" is displayed, the write operation is complete. Now the demonstration mode is initiated and the test mode is terminated. (Note) In the same way as previous models, if 30 minutes have elapsed with no code written, an error occurs and the power is turned OFF. 5. Method of initializing the Mask key (How to reset the unit from the Mask key approved condition to the factory condition) (1) Enter the test mode. (See "1. How to enter the test mode") (2) "TRANSMIT1" is displayed and the Mask key entry request mode is initiated. The display at this time should show "� �" in place of "[ ]". (3) Press and hold the key on the Master key remote for more than 3 seconds. (4) When "TRANSMIT2" is displayed, press and hold the key on the Master key remote for more than 3 seconds again. (5) When "APPROVED" is displayed, the Mask key is cleared, the demonstration mode is initiated, the test mode is terminated and the unit returns to the factory condition. 6. Method of clearing all Mask key-related data (1) Enter the test mode. (See "1. How to enter the test mode") (2) Press the [4/8] key to enter the Mask key registration mode. "TRANSMIT1" should be displayed now. (3) Point the Master key remote toward the light sensor, and press and hold its key for more than 3 seconds (until the level display shows the full condition). (4) When "TRANSMIT2" is displayed, hold the key on the Mask key remote for more than 3 seconds again. If " TRANSMIT1 "is displayed in place of" TRANSMIT2 ", restart the procedure from step 3. (5) When "APPROVED" is displayed, all security data is cleared and the unit returns to the condition before Mask key writing with the EEPROM in the initial status
