7. GENERAL INFORMATION

7.1 DIAGNOSIS
7.1.1 PROTECTION CIRCUIT CONTROL SPECIFICATION Microcomputer-related ports 2 Overload detection FAN_DRIVE (Expansion IC) : For Fan on/off (abnormality detection)
TEMP_IN (pin 94) Input port (A/D) : To detect temperature FAN_STOP (pin 95) Input port : To detect Fan forced stop OL_DET (pin 73) Input port : To detect overloading at the amplifier (Interrupt port) DC_DET (pin 63) Input port : For DC detection The following control processes are activated immediately before the relay system is turned on upon power-on. The time is 4.8 seconds after power-on. (Control of the relay system is enabled 5.2 seconds after power-on.) Only DC detection is enabled 2 seconds after power-on to activate it before other protection functions. If the speaker terminals are short-circuited or low-load driving is detected, the OL_DET port becomes "L" Detecting "L" edge interrupt in an interrupt process, the microcomputer performs the following operations: 1. System muting on 2. Speaker relay off (Control with the display microcomputer) 3. Power off (Standby mode)
3 DC detection (defect detection)
Only DC detection is enabled 2 seconds after power-on. If there is a fault in the power amplifier or a high-level signal lower than5 Hz is input, the DC_DET port becomes "L" Detecting "L" the microcomputer performs the following operations: 1. System muting on 2. Speaker relay off (Control with the display microcomputer) The warning indication "AMP ERR" appears on the FL display. If this status continues for more than 3 seconds, the power is turned off (for Standby mode) and flashes the standby LED. Do not accept the key input afterward. (Flash it always till turns the primary side off.) If the port becomes "L" within 3 seconds, the unit resets automatically. DC_DET port performs the chattering check for 1 msec. In addition, there is the case that detection delays for maximum 20 msec because performs monitor of DC_DET port with a main loop. Even if turns the primary side off and turns on once again, standby LED flashes as it is. If detects DC once and turned the power off, do not accept the key input afterward. However, power on is possible when the following key was pressed to be able to key input in the protection line and service. 1. Test mode (remote control code : A55F) 2. When the STEREO/DIRECT key and SIGNAL SELECT key are both held pressed for 2 seconds. (Be effective when turned the power off by DC detection regarding 2.)

7.1.3 TROUBLE SHOOTING

When a sound is not out in the surround mode with the digital signal input. Suppose CR to be poor contact and that is not damaged. This shows failure analysis of DSP Assy.

Step 1

Step 3
IC201 Is SPDIF signal coming ? (be different with Function) Insert it tight Coax1 (pin 44) Yes CN601 Confirm the poor contact of lead wire of CN101-pin 16. Insert it tight Yes Coax2 (pin 46) No Check the COXIAL IN Assy or OPTICAL IN Assy and so on.

Is FFC inserted tight ?

Is FFC inserted tight ? Yes CN102 Is connector inserted tight ? Yes

Insert it tight

Confirm the poor contact of lead wire of CN101-pin 14. Yes Opt in1 (pin 48)
No Check the COXIAL IN Assy or OPTICAL IN Assy and so on.
End Confirm the poor contact of lead wire of CN101-pin 12. No Check the COXIAL IN Assy or OPTICAL IN Assy and so on.

Step 2

Yes Opt in2 (pin 1)
Is there the input of 5V ? Yes Is 3.3V outputting it ? Yes IC902

Check CN102

Confirm the poor contact of lead wire of CN101-pin 10. Yes
RF Demodulator (pin 3) Replace IC901 Confirm the poor contact of lead wire of CN101-pin 8. Yes No Check the COXIAL IN Assy or OPTICAL IN Assy and so on.
Is 1.8V outputting it ? Yes End

Replace IC902

USB (pin 5)
Confirm the poor contact of lead wire of CN101-pin 6. Yes

Front Opt in (pin 42)

Confirm the poor contact of lead wire of CN102-pin 18. Yes MCK (pin 23)
No Check the DSP CONNECTION Assy or REGULATOR Assy and so on.

Pin 31 Is input signal H? Yes Pin 10 Is input signal L? Yes Pin 29 Is oscillating it ?
Confirm the poor contact of lead wire of CN102-pin 21.
Check the DSP CONNECTION Assy or REGULATOR Assy.

Replace IC401

Replace IC201 or X201

LRCK (pin 24)
