2. Safety check out

(U.S.A. model only) After correcting the original service problem, perform the following safety check before releasing the unit to the customer. Leakage current Check Measure the leakage current to a known earth ground (water pipe or conduct etc.) by connecting a leakage current tester between the earth ground and exposed metal parts of the unit (input/output ground terminals, screw heads or metal overlays etc.). Plug the power supply cord directly into a 120Vac 60Hz wall socket and turn ON/STANDBY button on. Any current measured must not exceed 0.5mA.

3. To initialize the unit

Press ON/STANDBY button while pressing down VCR/DVR(TX-NR525/HT-RC550 is CBL/SAT) button when the unit is POWER ON, then the FL displays "CLEAR", and turn to STAND-BY. Remove power cord from power line.

4. To check version of each Firmware

a. Push STANDBY/ON key while pushing down DISPLAY key to display MMPU(Main Microprocessor) version.

e.g.

b. In display version, -(TONE) key and +(TONE) key are pushed to display another F/W version.

e.g.

M1.01/13204ALN

(TONE)

M1.01/13204ALN

SERVICE PROCEDURE-2

5. Notes on repairs (Power supply board)

Some parts on BAPS-1333 may remain high voltages even after the power cord is disconnected from AC power source. Before starting repair and any other work , please discharge C9002 by connecting resistors between its terminals. See the figure below(recommended resistor spec: 5 k ohms/ 10W) It is dangerous to touch the "HIGH VOLTAGE PRIMARY" area surrounded by white lines without discharging.

AUDIO DEBUG MODE-1/5

The operations of DSP and DIR etc are able to checked by the information displayed on FL in this debug mode. This information will help to analysing digital audio no sound trouble.

To set in Debug mode

1. Press twice the ON/ STANDBY key while pressing the DISPLAY key.

2. Press + (TONE) button while the version number of microprocessor is displayed.

3. Press DISPLAY button while the version number of DSP is displayed.

4. Proceed to the next step by pressing the DISPLAY key.

OPERATION CHECK-1

1.OPERATION CHECK(1/2)

1-1. OPERATIONS OF VOLTAGE-DETECTION PROTECTORS.

See “OPERATION CHECK-3,-5” for TEST MODE operation. NOTE: Don't connect load nor short speaker terminals. a. Change the state to "TEST-4-21".

b. It tests by being automatic in order of TEST 4-21(FL+) → 22(FR-) → 23(C+) → 24(SL-) → 25(SR+) → ( 26(SBL-) → 27(SBR+) ). If TEST 4-27(TX-NR525/HT-RC550 are 4-25) is OK, it becomes the display of "TEST-4-35". c. It will complete, if displayed on FL TUBE as "TEST 4-35".

1-2. OPERATIONS OF CURRENT-DETECTION PROTECTORS

See “OPERATION CHECK-3,-5” for TEST MODE operation. a. Change the state to "TEST-4-35".

Even if you connect 3-ohm load for every channel of L, R, C, SL, SR, SBL and SBRch, a relay should not cut off. If 1-ohm load is connected for every channel of L, R, C, SL, SR,SBL and SBRch, a relay should hold the state of ON.

1-3. CONFIRMATION OF RDS (RADIO DATA SYSTEM) OPERATION (Applied to MM*/MP* type )

a. Input 98MHz,30dBμ signal modurated with RDS data.

b. When a PS information is received, the name of the station "RDS TEST" shall be displayed within 2 seconds instead of the frequency.

1-4. CONFIRMATION OF HEAD PHONE OPERATION.

Confirm the Listening Mode is automatically switched to "STEREO" mode when headphones plug is inserted into the PHONES jack.

1-5. COMFIRMATION OF FRONT USB

See “OPERATION CHECK-3,-4” for TEST MODE operation.

a. Connect ipod to AVR USB port. b. When set to TEST 3-09, confirm that the display of AVR change "connecting" to "Push [MODE] b ..." or "Playlist" after

few seconds. The following iPod models can be used for inspection.(The above-mentioned operation is not done excluding the following items.) iPod classic, 3G nano, 4G nano, 5G nano

1-6. COMFIRMATION OF REAR USB(Applied to TX-NR525/HT-RC550)

See “OPERATION CHECK-3,-4” for TEST MODE operation.

a. Connect USB-Storage to AVR USB port. b. When set to TEST 3-10, confirm that the display of AVR change device name.

1-7. COMFIRMATION OF NETWORK(Only TX-NR525/HT-RC550)

See “OPERATION CHECK-3,-4” for TEST MODE operation. a. Connect the receiver to the router. b. When set to TEST3-18 confirm that the display of AVR change IP adress. *Please wait for about 1 minute after turning on the power supply of the set when you use TEST 3-18.

1-8. CONFIRMATION OF OUTPUT SENSER AND THERMAL SENSOR

See “OPERATION CHECK-3,-5” for TEST MODE operation.

a. Set the TEST MODE to "TEST 4-36" and "TEST 4-37".

After light "FM STEREO" on FL display ,

the relays RL641/642 is OFF and "FM STEREO"is off .(TEST 4-37 is only for HT-R592) b. Push ON/Standby button 2 times while pushing down DISPLAY button to display CPU Debug PROGRAM version.

Push TONE button while displaying CPU PROGRAM version to display value of temparature sensor.

Confirm outside temperature ±20C is displayed immediately after energizing.

Note that the error margin is caused by the rise of the temperature of the heat sink when time passes.
