Very complete and well reading drawings. Documentation is essential for successful repairs.Good documentation, with all that is necessary. This manual was what I was waiting with all the information necessary for the repairing I need it for. You must buy it if you want to do repairs or simply understand how it works.

Reading the Display: Convert the hexadecimal display of each digit into binary display. If more than two causes, they will be added. Example When 42 is displayed: Higher bit: 4 = 0100 → b6 Lower bit: 2 = 0010 → b2 In this case, the retry cause is combined of “CLV unlock” and “ader5”. Example When A2 is displayed: Higher bit: A = 1010 → b7+b5 Lower bit: 2 = 0010 → b1 In this case, the retry cause is combined of “ACCESS default”, “IVRrec” and “ader5”. The reading of the track mode display is as follows.
Hexadecimal Bit Binary
Higher Bits 8421 b7 0 0 0 0 0 0 0 1 b6 0 0 0 0 0 0 1 0 b5 0 0 0 0 0 1 0 0 b4 0 0 0 0 1 0 0 0
Lower Bits 8421 b3 0 0 0 1 0 0 0 0 b2 0 0 1 0 0 0 0 0 b1 0 1 0 0 0 0 0 0 b0 1 0 0 0 0 0 0 0
Hexadecimal When 0 01 02 04 08 10 20 40 80 Emphasis OFF Monaural 2-bit display, normally 01 01: Normal audio, Other: Invalid Audio (normal) Original Copyright exists Writing is prohibited
Contents When 1 Emphasis OFF Stereo
Invalid Digital copy No copyright Writing is allowed
Reading the Display: Convert the hexadecimal display of each digit into binary display. The several causes are added and displayed. Example When 84 is displayed: Higher bit: 8 = 1000 → b7 Lower bit: 4 = 0100 → b2 This example shows that “Emphasis: OFF”, “Monaural”, “Original”, “Copyright exists” and “Writing is allowed” because b2 and b7 are 1 while all other bits are 0. Example When 07 is displayed: Higher bit: 0 = 0000 → all 0 Lower bit: 7 = 0111 → b0+b1+b2 This example shows that “Emphasis: ON”, “Stereo”, “Original”, “Copyright exists” and “Writing is prohibited” because b0, b1 and b2 are 1 while all other bits are 0.
Hexadecimal → Binary Conversion Table Hexadecimal 0 1 2 3 4 5 6 7 Binary 0000 0001 0010 0011 0100 0101 0110 0111 Hexadecimal 8 9 A B C D E F Binary 1000 1001 1010 1011 1100 1101 1110 1111
