1. Before Repair
1. Turn off the power supply. Using a10 , 10 Wresistor, connect
both ends of power supplycapacitors (C601, C602) inorder to
discharge the voltage.
2. Before turning the power supplyon, after completion of repair,
slowlyapplythe primaryvoltage byusing apower supplyvoltage
controller to make sure that the consumed current at 50 HzinNO
SIGNALmode shouldbe shownbelow with respectto supply
voltage 240 V.

2. Protection Circuitry
The protection circuitrymayhave operatedif eitherof the following conditions is noticed:
-Nosound isheard when the power issupplied.
-Sound stops during aperformance.
The functions of this circuitryis toprevent circuitrydamage if, forexample, the positive and
negative speakerconnection wires are shorted, orif speakersystems withanimpedance less
thanthe indicatedratedimpedance of this unit are used.
If this occurs, followthe procedure outlinedbellow:
1. Press the Standby/on button, switch to standbymode.
2. Determine the cause of the problem and correct it.
3. Press the Standby/on button once again, supplythe power.
Note:
When the protection circuitryfunctions, the unitwill not operate
unless the Standby/on button isfirst switched Standbyand then
ONagain.

2. Connect the AC power supplycord to the Amplifier / (SE-HD550).
Refer to Fig. 6-1.
3. Connect the speakers to speaker terminal. / Refer to Fig. 6-1.
4. Turn on the power of the Amplifier (SE-HD550).
5. Set INPUTSELECTERto select the external source (EXT) of the
Amplifier (SE-HD550).
6. Input asound signal to external input terminal of the Tuner (ST-
HD550), and confirm to be outputted from the speaker. (Both High
and Low.)

-Indicated voltage values are the standard values for the unit
measured bythe DC electroniccircuittester (high-impedance)
with the chassistaken as standard. Therefore, there mayexist
some errors inthe voltage values, depending on theinternal
impedance of the DC circuittester.

-Important safetynotice:
Components identified bymark have special characteristics
important for safety.
Furthermore, special parts which have purposes of fire-retardant
(resistors), high-qualitysound (capacitors), low-noise (resistors),
etc. are used.
When replacing anyof components, be sure to use only
manufacturer’sspecified parts showninthe parts list.
-The supplypart number isdescribed alone inthe replacement
parts list.
-Caution!
