SERVICE PROCEDURES
HT-R820THX
1. Replacing the fuses
This symbol located near the fuse indicates that the
fuse used is show operating type, For continued protection against
fire hazard, replace with same type fuse, For fuse rating, refer to
the marking adjacent to the symbol.
Ce symbole indique que le fusible utilise est e lent.
Pour une protection permanente, n'utiliser que des fusibles de meme
type. Ce demier est indique la qu le present symbol est apposre.
3. To initialize the unit
This device employs a microprocessor to perform various
functions and operations. If interference generated by an external
power supply, radio wave, or other electrical sauce results in accident
which causes the specified operations and functions to operate
abnormally.
To perform a result, please follow the procedure below.
1. Press and the hold down the VIDEO 1 button, then press the
STANDBY/ON button when the unit is Power On.
2. After "Clear" is displayed, the preset memory and each mode
stored in the memory, are initialized and will return to the
factory settings.

2. Safety-check out
After correcting the original service problem perform the
following safety check before releasing the set to the customer
Connect the insulating-resistance tester between the plug of
power supply cord and terminal GND on the back panel.
Specifications: More than 10Mohm at 500V
The HT-R820THX uses a battery-less memory backup
system in order to retain radio presets and other settings
when it's unplugged or in the case of a power failure.
Although no batteries are required, the HT-R820THX
must be plugged into an AC outlet in order to charge the
backup system.
Once it has been charged, the HT-R820THX will retain
the settings for several weeks, although this depends on
the environment and will be shorter in humid climates.

<Regarding the power supply system of this unit>
Function
1. High-voltage mode
Usually, the power supply supplies high voltage to the power amplifier circuit when the relay (RL6901) is turned On.
2. Low-voltage mode
When as follows, a power supply changes to the state of supplying low voltage when the relay (RL6901) is turned Off.
(1) Excessive output signal is continuously outputted from power amplifier.
(2) Temperature of a heat sink over 80 degrees.
Purpose
1. The loss which power amplifier generates is decreased. As a result, the miniaturization of a heat sink is realized.
2. Corresponds to a safety standard.
<Procedure>
<Note>
Don't connect speakers or any load.
Don't short speaker terminals.
(1) Set the unit is Multi channel input state.
(2) Set the master volume into the minimum.
(3) Apply sine wave signal to MULTI CHANNEL INPUT (FL+FR+C+SL) terminals.
(4) Connect an oscilloscope to speaker terminal of FL channel.
(5) Adjust master volume so that the wave form of speaker output may become distortion about 5%.
(6) Check that the RL6901 is turned off after about 5 seconds.
And the power supply changes to low-voltage mode.
(7) Adjust the master volume so that output voltage may become half.
(8) Check that the RL6901 is turned On after 2 to 3 minutes.
And the power supply returns to high-voltage mode.
Necessity of operation check
May not notice the fuse (F6901, F6902) broken in the case of repair.
Because the power supply is continuing supplying voltage from the High side of SEC1 at high-voltage mode.
When a power supply Circuit changes to low voltage mode, amplifier does not operate.
Therefore, it is very important to check operation of this power supply system containing a fuse.
