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.

Diode switch (SWx) 0 = diode no (It becomes LOW input in the case that it is static)
(It becomes HIGH input in the case that it is static) There is 1 = diode X = transistor switch (0 = OFF / 1 = ON)
A phase locked loop standard frequency is the value that set up it to a phase locked loop.
This value becomes same a dividing ratio of amplitude modulation with a phase locked loop standard frequency. However, a dividing ratio of frequency modulation becomes 2 times of phase locked loop standard frequencies.

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 CENTER/REAR EFFECT 1step

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.
