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%). x RD1/4PU 1 J 561 47k RD1/4PU 3 J 47 x 473 0.5 RN2H R K RRS1P 1 R 0 K 1R0 Ex.2 When there are 3 effective digits (such as in high precision metal film resistors). 5.62k 562 x 5621 RN1/4PC F

1. DC Abnormality Detection
This detection has priority over the overload detection and abnormality detection for the fan and thermistor.
When detect DC abnormal, Amute on and speaker relay off, then flash "AMP_ERR" on the display.
An unusual state continues for 3 seconds. continuation A power supply is shut off. return A program is performed from the beginning.
Power key cannot effective 60 seconds.
If AC plug is pulled off within 60 sec, then AC plug in again, receiver will reset for

2. Overload Detection

This detection has priority over the abnormality detection of the fan and thermistor.
When detect overload, Amute on and speaker relay off, then flash "OVERLOAD" on the display.
An unusual state continues for 3 seconds. continuation A power supply is shut off. return A power supply is shut off even if it returns.
While the unit is recovering from the abnormality, the "OVERLOAD" display continues flashing.
3. Specifications of DSP Overload Detection
1. Detect overload detection signal of DSP in the port and light a "OVER" segment if detected for 30 seconds. Light it for 1 second if lighted once. 2. Do not detect in the following case.

If you wish to switch FAN START from "H" to "L" and FAN MAX from "L" to "H," first set FAN START to "L," then after 100 s, set FAN MAX to "H." While "OVERHEAT" is flashing, only the POWER key is functional.

3. FAN operation

Once the fan starts rotating, it continues to rotate at the same speed until the temperature falls to 65C. Once the fan starts rotating, it continues to rotate for at least 20 seconds even after the temperature falls to the above-mentioned level.
4. Detection of abnormalities in the fan
If any abnormality is detected in the fan 5 seconds after it starts rotating at high speed, and if H (abnormal) is indicated for the FANDCT connector, "FAN STOP" is displayed for 5 seconds, then the power is turned off. While "FAN STOP" is displayed, AMUTE is on, and RELAY is off. While "FAN STOP" is displayed, only the POWER key is functional. While the fan is rotating at low speed, abnormality detection is not carried out.
5. Abnormality in the thermistor
If an abnormality (A/D voltage: 0.1 V or less) is detected in the thermistor, "THDCT NG" is displayed for 5 seconds, then the power is turned off.

7.1.4 Specications of Speaker Detection

1. Purposes

Whether the speakers are connected or not is automatically detected, and settings appropriate for the detected speakers are made to allow you to easily play surround-sound without making cumbersome speaker settings.
2. Method of detecting speakers
Whether a center speaker, surround speaker and/or subwoofer is connected or not is detected 600 ms after the power is turned on. < Detection of the center and surround speakers > The microcomputer sends a detection signal and after 10 ms will read the logic of the responding signal to judge whether the speaker is connected or not. The response signal will be read at A/D. A voltage of 3.5 V or more is judged as no speaker connected. The response signals at A/D are read every 2 ms, and if the same results (less or more than 3.5 V) are obtained, the detection result is considered correct. If a different result is obtained for the second detection, a third detection is carried out, and the two results that agree will outvote the other. If detection fails three times, then it is judged that no center speaker is connected. < Detection of the subwoofer > The logic of the signal from the phono jack with a switch is read by the microcomputer to judge whether the speaker is connected or not. The signals are read every 1 ms, and if the same results are obtained, the detection result is considered correct. If a different result is obtained for the second detection, a third detection is carried out, and the two results that agree will outvote the other. If detection fails three times, then it is judged that no subwoofer is connected.

3. Speaker settings

According to the results of the detection, speaker settings are made as follows: Results of the Detections

4. User's settings

In Setup mode, more detailed speaker settings are available. Once the user's settings are made, those settings have priority. However, if the configuration of connected speakers has changed, then the detection results become valid and have priority over the user's settings until new user's settings are made.

When FAN is not connected between FAN+ and FAN-, or an alien substance is clogged up in the FAN at the FAN LOCK status, FAN STOP becomes the same electric potential as the FAN- (Low). -COM detects it, and turn the power OFF.
A speaker (6) is connected between FL and GNDFL normally. Q305 (306) (345) (346) (383) does not work because the voltage of A point is higher than B point. If a resistance value between FL and GNDFL becomes less than 1.2, Q305 (306) (345) (346) (383) turns ON. And ODCT becomes with negative component of output level. -COM detects it, and turn the power OFF.

STANDBY/ON (Main power) button 1 Pressing this button switches the receiver ON from STANDBY mode. RECEIVER button on the remote control also toggles between ON and STANDBY mode. The receiver uses a small amount of electricity (less than 1W) in STANDBY mode. 2 PHONES jack Use to connect headphones (this switches the speakers off). 3 FRONT INPUT You can connect a portable DVD player, video camera, video game system, or whatever equipment you would like to have handy, to the FRONT INPUT. 4 INPUT SIGNAL indicators Indicates the kind of input signal. DIGITAL: When a DIGITAL source is input this indicator will light. DTS: When a DTS source is input this indicator will light. 5 SURROUND MODE indicators Indicates the SURROUND mode of input signal. AUTO: Lights when the AUTO mode is selected. This mode automatically selects which kind of signal is being input and plays back in the appropriate mode. PHONES/VIRTUAL: Lights when the VIRTUAL or PHONES SURROUND mode is selected. The VIRTUAL mode simulates surround sound for two speakers (when headphones are not plugged in, see). The PHONES SURROUND mode simulates surround sound for headphones, when they are plugged in. PRO LOGIC II: Lights when the PRO LOGIC II mode is selected. This mode automatically plays back in PRO LOGIC II. ADVANCED: Lights when an ADVANCED mode is selected. These modes playback emphasizing certain characteristics of the sound. 6 SOUND MODE Lights when you have chosen one of the sound modes to be applied to playback. 7 Input buttons Use to select the playback source: the possibilities are DVD, TV/SAT, DVR/VCR, FM/AM and FRONT. 8 MASTER VOLUME Use to set the overall listening volume.
