Many electrical and mechanical parts in the appliance have special safety related character istics. These are often not evident from visual inspection nor the protection afforded by them necessarily can be obtained by using replacement components rated for voltage, wattage, etc. Replacement par ts which have these special safety character istics are identified in this Service Manual. Electr ical components having such features are identified by marking with a on the schematics and on the parts list in this Service Manual. The use of a substitute replacement component which does not have the same safety characteristics as the PIONEER recommended replacement one, shown in the parts list in this Service Manual, may create shock, fire, or other hazards. Product Safety is continuously under review and new instructions are issued from time to time. For the latest infor mation, always consult the current PIONEER Service Manual. A subscription to, or additional copies of, PIONEER Ser vice Manual may be obtained at a nominal charge from PIONEER.

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

Use these terminals to input the signal from a DVD, CD player or any other kind of digital player. To be able to play Dolby Digital and other surround soundtracks you need to make digital connections. To do this use the digital terminals here. If you don't connect as per the default settings you need to complete "Assigning the Digital Inputs".
