5. PCB PARTS LIST Parts marked by "NSP" are generally unavailable because they are not in our Master Spare Parts List.The mark found on some component parts indicates the importance of the safety factor of the part.Therefore, when replacing, be sure to use parts of identical designation.When ordering resistors, first convert resistance values into code form as shown in the following examples.Ex.1 When there are 2 effective digits (any digit apart from 0), such as 560 ohm and 47k ohm (tolerance is shown by J=5%, and K=10%).
Ex.2 When there are 3 effective digits (such as in high precision metal film resistors).

In Normal mode, the speaker (6 ohms) is connected between the FL and GND FL points. Because the voltage at Point A is higher than that at Point B, Q3601 does not operate.
If the resistance between the FL and GND FL points becomes 1.83 ohms or less, Q3601 begins to operate, Q3602 is turned on, Q3603 (E, C, and B)is turned on, and the level of XPROTECT becomes MID.

• In Normal mode, as Q101 (Q103) (E2, B2, C2) and Q102 (Q104) (E2, B2, C2) are on, the voltage at Point A is about 5 V. The voltage at Point B is therefore about the same. As Q101 (Q103) (E, C, B) is off, Q102 (Q104) (E, C, B) is also off.
(1) When VH+(VP+15) is short-circuited to GNDAs the voltage at Point B becomes almost ground potential, and Q101 (Q103) (E, C, B) then Q102 (Q104) (E, C, B) are turned on, the level of XPROTECT becomes low.
→ The microcomputer detects the XPROTECT level and shuts the power to the unit off.
(2) When VH-(VA-12) is short-circuitedAs the electric potential of VE at Q102 (Q104) (E2, C2, B2) becomes the same as that at VB, Q102 (Q104) (E2, C2, B2) is turned off. Following this, Q101 (Q103) (E2, B2, C2) is turned off, which changes the voltage at Points A and B to a value other than 5 V. Therefore, Q101 (Q103) (E, C, B) then Q102 (Q104) (E, C, B) are turned on, the level of XPROTECT becomes low.
(3) When VD+5 is short-circuitedThe level of the XPROTECT line becomes low. The microcomputer detects the XPROTECT level and shuts the power to the unit off.

As the TUNER line is fixed to GND level, Q107 is always on. If the level at VP+8 falls to GND level because of short-circuit, etc., Q106 is turned on, and the level of the XPROTECT line becomes low.
← The microcomputer detects the XPROTECT level and shuts the power to the unit off.

FAN–
If no fan is connected between FAN+ and FAN-, or when the fan cannot rotate because of a foreign object caught in the blades, current will not flow to R3657, and Q3652 and Q3651-1/2 (E, C, B) are turned off. Then Q3651-2/2 (E2, B2, C2) is turned on, and the level of XPROTECT becomes low. → The microcomputer detects the XPROTECT level and shuts
the power to the unit off.
When FAN+ and FAN- are short-circuited, the electric potential at Point A becomes higher than GND level by the addition of the values at D3656 and D3657. As this value is lower than that at D3658, Q3651 (E, C, B) is turned off, Q3651 (E2, B2, C2) is turned on, and the level of XPROTECT becomes low.

• In Normal mode, both Q3605 and Q3604 are off.
(1) When positive (+) DC voltage is generated at the SP terminal
When positive (+) DC voltage is generated at the L or R channel, and VB of Q3605 becomes higher than that at the operation point, Q3606 (E, C, B) is turned on, and the level of XPROTECT becomes low.
→ The microcomputer detects the XPROTECT level and shuts the power to the unit off.
(2) When negative (-) DC voltage was generated at the SP terminal
Q3604 is turned on, and XPROTECT is activated.
5 IC81 abnormal temperature detection circuit
A
The voltage at Point A becomes the divided voltage of TH111 and R111//R112 (combined resistance of parallel-connected resistors R111 and R112.) In Normal mode, the resistance at TH111 is much higher than R111//R112, and Q111 is off. (Note that the resistance at TH111 becomes lower as the temperature increases.) If the solder temperature at IC81 increases abnormally, the temperature at TH111 (thermistor) mounted closest to the land of IC81 increases accordingly, and the resistance at TH111 decreases.When the temperature at TH111 reaches 90-110_C (varying according to conditions,) the voltage at Point (A) becomes high enough to turn Q111 on, and the level of the XPROTECT line becomes low. The microcomputer detects the XPROTECT level and shuts the power to the unit off.
