DISASSEMBLY FOR REPAIR

The method that exchanges a power transistor.

1. Remove 10 screws (1 and 2) of rear panels.

2. Remove flat cable from connector (CN851 and CN852) of
printed circuit board X08 (A/3) . And, remove one screw
(

3). After this, move printed circuit board X08 (A/3)

toward the right.

3. Remove one screws (

4) of printed circuit board X08
(B/3). After this, move printed circuit board X08 (B/3)
toward the right.

4. 1) Cut certain 4 convenes with nippers etc. on the left side
of the power supply transformer.

2) Remove one screws (

6) of printed circuit board X14

(C/5). And, remove a headphone unit.

3) Remove 4 screws (7) of printed circuit board X09.

• Make printed circuit board X08 (A/3 and B/3) in

original condition, after screw (

4) is removed. And,

remove screw (

1 and 3) and FFC.

5. Remove 2 screws (

8) of both sides of a panel.

6. Set up a receiver, so that the left side of a receiver
becomes downward. And, remove 4 screws (

9). Turn

over a receiver like a figure after this.

7. Remove 5 screws (0) on the side of under of a panel.
Next, remove 2 screws of radiators on the side of a base.
And, remove a base plate to the back side (arrow
direction).

8. Remove the solder of a power transistor from FOIL side of
printed circuit board X09. And, exchange a power
transistor.

CIRCUIT DESCRIPTION

7. Test mode

(1) Test mode setting method

Turn on the power supply while pressing TUNING­DOWN key, to make a set in test mode condition.
When a set is set up in test mode condition a set
becomes the following condition.
Automatic POWER ON
All indicator tubes and also LED are lighted. (This
condition can be canceled by pressing the key of the
set.)
A backup at the thing except ON/OFF of POWER is
initialized.

(2) Test mode cancellation method

The power supply is turned off.
"Usually display / All the turn-off" is periodically repeated
by operating MEMORY key.

(3) A tuner function.

When a selector is set to the tuner, the following key is
not usual function and operates by the special function.
The function to summon the channel of the presetting

1

The following channel is summoned when not

operating +10 keys.
1ch~9ch (1~9key)
10ch (0key)

2

When +10 keys are pressed once, the following

channel is summoned.
11ch~19ch (1~9key)
20ch (0key)

3

When +10 keys are pressed twice, the following

channel is summoned.
21ch~29ch (1~9key)
30ch (0key)

4

When +10 keys are pressed three times, the following

channel is summoned.
31ch~39ch (1~9key)
40ch (0key)

5

When +10 keys are pressed four times, it gets to do

the function which is the same as the condition which
doesn’t press +10 keys.

• The S level hexadecimal DATA display and the
ATT ON/OFF function

When a selector is set to the tuner, it repeats the
following operation cyclically when operating the
PTY key of the set.

a) When ATT is in the OFF condition, it displays

as follows.
“ATT OFF display” + “Signal level display by
the tuner (HEX DATA)”

b) When ATT is in the ON condition, it displays as

follows.
“ATT ON display” + “Signal level display by
the tuner (HEX DATA)”

c) At the time of the ATT OFF condition, the set

becomes usual display.

✰ When the key of a set is pressed a signal level

display of a tuner continues to display the value of
when that ATT works.

• MUTE signal output
Because TUNER-MUTE always becomes OFF
condition, it isn’t possible to do control.

• When a selector is set to the thing except TUNER,
each key does usual function.
Then, the test mode doesn't work.

• RDS display mode.
RDS-PS display works by pressing PRO-LOGIC
key irrespective of TUNED. (It is able to cancel it
by pressing PRO-LOGIC key.)

• I

(4) An amplifier function.

• The value in the first of the speaker setting by the test
mode is full equipment.

• When a selector is set to the thing except TUNER, the
following key works by the special function.
When a selector is set to TUNER, the following key
does usual work.

• The way of setting MAX/MID/MID of AUDIO
LEVEL/SURROUND LEVEL easily.

• AUDIO LEVEL/SURROUND LEVEL is variably made
of MULTILEVEL UP/DOWN operation. When a
selector is set to the thing except TUNER, operate a
number key. MAX/MID/MIN can be set by the
following operation.
It is set in as follows at the time of MID.

Master volume Intial value
Balance Center
BASS/TREBLE/SUB WOOFER/ 0dB or a 0step

3 Test tone operation

While displaying as follows every time it presses
DIRECT key when dolby surround is working, it
switches a speaker and TEST-TONE is output.
By pressing DIRECT key, this work and dolby
surround can be canceled.

4

Mute signal output

Because the analog mute always becomes OFF
condition, it isn’t possible to control absolutely.
however, when the value with front volume is the
minimum, it becomes an analog mute ON condition.

5 AC-3 The 6ch input changing.(Only KR-V9090)

When the selector of KR-V9090 is VIDEO2, press
"AUTO/MANU" key. At this time, KR-V9090 becomes
"AC3 6ch input" condition. (M-INPUT is lighted).
"AC3 6ch input" condition is able to cancel by
pressing "AUTO/MANU" key. (It become usual
function).

6 The ADAPTER input changing.

Press the "BAND" key of KR-V9090. At this time, KR­V9090 changes to ADAPTER input. When "BAND"
key is pushed again, it is able to cancel it.

7 TONE BASS/TREBLE

When KR-V9090 is doing the function of the test
mode, the TONE BASS/TREBLE key does a function
below periodically.
