Check STBY 5V line.

Check STBY 12V line.

Check line between pins(21), (22) 

of  IC2501 and pins(17), (18) of 

IC701. 

Is voltage 5V applied to the video 

section power terminal at pins(24), 

(29) of IC2501?

Is voltage 12V applied to the 

audio section power terminal at 

pin(14) of IC2501?

Check signal line from video and 

audio function logic table as shown 

below.

Is there SDA and SCL signal 

applied to pins(21) and (22) of 

IC2501?

Servicing precautions

When the IC705(E

2

PROM) has been replaced, make the following reprogramming.

Depending on models, the IC705(E

2

PROM) has been factory adjusted for it s memory function.

It s therefor necessary to reprogram the memory function for the model in question.
Note that the servo circuit requires readjustments for the slow and still modes.

1. Memory function reprogramming.

1. Check the power off.(Power is standby mode)
2. Make for moment short-circuit test point(P802), located at the front side on the main PWB.

Be sure that all the fluorescent display tube light up into the TEST mode.

3. Using the CHANNEL(+) AND (—) buttons, select the right function numbers from JP0 to JP39, which appear in the

fluorescent display tube, referring to the E

2

PROM map.

Press the DISPLAY button to pickup the functions(ON) and the CLEAR button to discard the functions(OFF).
DISPLAY and CLEAR buttons, are located on the remote control unit.

∗

when the DISPLAY button has been pressed (ON), the memory function number starts flashing.

∗

when the CLEAR button has been pressed (OFF), the memory function number lights up.

4. Press the FF button on the remote control unit.

By doing, lower 7 of the 10 digits are displayed in hexadecimal notation.

5. Similarly to the above step 4, press the STOP button on the remote control unit.

By doing, upper 3 of the 10 digits are displayed in hexadecimal notation.

6. Example :  "ON" and "OFF" are taken as "1" and "0" respectively.

The numbers JP0 to JP39 are divided into four groups and each group s setting is displayed in hexadecimal notation.

1.Make sure that the condition of the set is POWER OFF mode.
2.Make the test point on the main PWB short-circuited condition momentarily. Or, transmit a test key (47h) from the

remote controller.
Make sure that all the fluorescent display tubes are turned on. After that, push the MENU button of the remote
controller.

3.Make sure that indication changed as the upper figure.

Input setting value to BF in turn from the data on C0. Setting value shows it in the attached table.Ten keys and an
operation key are used here.

A:PAUSE

D:STOP

B:FF

E:REC

C:REW

F:PLAY

4.Push the menu button of the remote controller again if input to BF from C0 is completed.At that time, CHECK SUM

is indicated. (It is indicated only while a menu button is being pushed.)."3AE5" is indicated when attached materials
are set up.
