13.3. (VHS) SELF-DIAGNOSIS FUNCTIONS
This model has a self-diagnosis. If the VHS section detects trouble during installation or during use, the power is automatically
turned off or become power-save mode and it is memorized into the EEPROM (IC37502) as error code of two-digit number. It
ｴ s
memorized error code can be displayed in "second" display portion (the last 2 digits of the FIP) by placing the unit is Service Mode
Number 2 when turning on the Service Information Display as for example "01" or "02" etc. as below. If a second error occurs, the
most recent error will be memorized and can be displayed in Service Mode Number 2. It can be memorized until 3 self-diagnosis
histories in maximum.
In order to erase the memorized error code, press FF and EJECT buttons on the Front Panel simultaneously over 5 seconds during
turning on Service Information Display mode.
13.3.1. MEMORY OF THE SELF-DIAGNOSIS HISTORY
*This is effective only in Service Mode 3, 4, 5.
13.3.1.1. ERROR NUMBERS AT A GLANCE
Memory No. (Error Code) Reason
01 The cylinder could not be started. (Error of the cylinder or the cylinder driver.)
02 The CAP FG could not be detected.
03 Mechanism lock during without the unloading and the cassette-up.
04 Mechanism lock during unloading
05 S-reel pulse cannot be detected during unloading. (Error of the S-reel circuit or the Capstan circuit)
06 Mechanism lock during the Cassette-up.
09 Communication Error between VHS Microprocessor and Timer Microprocessor.
15 S-reel pulse cannot be detected when a cassette tape is inserted.
(Error of the S-reel circuit or the Capstan circuit)
16 Detection of the Cylinder lock during the constant rotation
17 Detection of S-reel lock during the constant tape running
18 Detection of T-reel lock during the constant tape running
2*
Refer to following table
An error while the PG Automatic Adjustment
80 An exceptional ejection depends on a accidental error
Note:
2* is as follows.
20 NG1 in the PG Shifter Automatic Adjustment (The cylinder rotation is unstable during the automatic adjustment.)
21 NG2 in the PG Shifter Automatic Adjustment (The vertical sync signal is lacked while over 5 seconds on the alignment tape.)
22 NG3 in the PG Shifter Automatic Adjustment (The installing position of Heads to the cylinder is our of specification.
23 NG4 in the PG Shifter Automatic Adjustment (The servo is not locked to the cylinder for more than 10 sec.)
13.3.1.2. MEMORY FOR THE SELF-DIAGNOSIS HISTORY
3. The self-diagnosis result is memorized the state of the moment of detecting.
4. There are the histories from number 1 to number 3.
5. The latest error is memorized on history number 1, and then the old histories are shifted to the history number 2 and 3.
The error code memorized in the history number 2 and 3 is over-written by shift.
