• Safety Check after Servicing
Examine the area surrounding the repaired location for damage or deterioration. Observe that screws, parts and wires
have been returned to original positions. Afterwards, perform the following tests and confirm the specified values in order
to verify compliance with safety standards.
1. Insulation resistance test
Confirm the specified insulation resistance or greater between power cord plug prongs and externally exposed parts of
the set (RF terminals, antenna terminals, video and audio input and output terminals, microphone jacks, earphone
jacks, etc.). See table below.
2. Dielectric strength test
Confirm specified dielectric strength or greater between power cord plug prongs and exposed accessible parts of the
set (RF terminals, antenna terminals, video and audio input and output terminals, microphone jacks, earphone jacks,
etc.) See table below.
3. Clearance distance
When replacing primary circuit components, confirm
specified clearance distance (d), (d‘) between soldered
terminals, and between terminals and surrounding
metalic parts. See table below.

1. General Outline
Servo 1 CHIP (80 pin) IC used in DVR-4286W deals with the functions of exclusive Servo IC and Syscon IC which have
been used up to now, combining their functions, by software.
Because this 1 CHIP IC has not ANALOG AMP inside, every output signal from MOTOR should be input through special
amplification and waveform shaping (sine waveform-square waveform).
* Salient Features
• Drum & Capstan Motor soft control.
• Head sw pulse generation for rotating Heads (Video and Audio heads).
• QV SYNC signal generation during special operaing (playback) mode.
• Separation of V-SYNC signal from the C-SYNC signal.
• Digital auto Tracking soft management.
• REC CTL Signal generation (Recording mode).
• INDEX SEARCH Control (VISS).
• Various speed SLOW mode.
• Various speed CUE & REV mode.
• Auto play.
2. Servo System Organization
In VTR Servo System consists of two control systems: Rotating HEAD DRUM and CAPSTAN MOTOR to make tapes run
at regular speed.
The bolck diagram of VTR SERVO SYSTEM is shown in Fig (1). Now, we will examine the Capstan and Drum controls by
Software Digital SERVO.
This servo control consists of both of the speed control and the phase control and controls them by using ERROR q'ty
corresponding to a mark.
In the speed control, FG signal cycle is the Reference when the motors rotate normally and really motors output the FG
signal. In the phase control, FG signal cycle is generated inside u-COM if being not input from outside.
Phase error is timing difference in the PG signal output from Motors and phase reference signal and it is indicated as
(Table 1) shows the signal used in the phase control.

Drum servo functions to control the DRUM motor mainly and set the drive cycle during SLOW and make, SW PULSE,
Q.V. SYNC, and AFM SW PULSE.
D.FG and D.PG signals output in DRUM MOTOR are used as comparison signal of phase and speed.

Drum and capstan Controls basically consist of SPEED and PHASE system servo control, by combining each error q'ty of
them.
In the phase control, phase reference signals are made arbitrary pulse of about 25Hz is obtained inside during the play-
back.
In the REC mode, reference signals synchronized V.SYNC.
Calculate the difference of the rising edges of the feed back signal of D.PG and Reference signal made in IC and stabilize
the phase loop by passing the ERROR through the digital filter, the phase compensation fitter. And then output it on the
phase control routine, multiplying by GAIN Kp.
DRUM motor drives by Combining the phase error output in the phase routine and speed error.
Because GAIN doesn't change variously in the DRUM system, special power amplification from outside is not required.
D.PG signal is used as producing the SW PULSE for Video HEAD SW.
The shaping circuit of D.PG signal is shown below.

Regarding D.PG signal, in Fig (3) goes through C506 and after amplificed by Q501; It is input into pin no. 1 of IC601.
Speed control system controls the speed by comparing the Reference set inside and D.FG signal when Motor rotates.
Method and waveform Shaping circuit for Speed control are as follows.
D.FG signal in Fig (4) goes through C510 and after 1.5Vp-p is input to pin no 6 of OPAMP, it is Schmitte trigger by R521
and R520 and becomes waveform shaping.
/Vaveform shaped D.FG controls the speed by comparting the reference with the difference value to subtract the current
:ycle value from the previous D.FG cycle value.
When the D.FG cycle rotates normally, that is in case it is wider than a target current Drum speed is slow and (+) mark is
selected. (Rotate the DRUM fast)
n case the D.FG cycle is narrower than the target, current speed is fast and (-) mark is selected. (Rotate DRUM slowly)
4. Capstan Servo Operation
Capstan Servo has functions of viss detection, REC CTL PULSE generation and REC CTL DITTY adjustment variously
during VISS, including the function to control the capstan motor.
Capstan speed control has same block in every mode and phase control has different block in each mode of REC and
PB. Capstan control also consists of phase and speed system as DRUM control. Capstan phase control is to maintain the
phase relationships between PB CTL signal and VIDEO SW/P regularly. PB CTL signal production process and phase
control method are as follows.
R505
+5V- W/-
P502
"1 CTL(-)
2 CTL(+)
3 GND
"------ ► P/CTL
R515
CTL signal input via C501 at CTL HEAD is amplified 4000 times by R502 and R504.
And the then it makes PB CTL PULSE of 0.4Vp-p SCHIMITTE with through R509 and it is input to pin no 11 of IC601.
Error is generated as comparing the PB CTL signal input to pin 11 of IC601 to the reference signal for CAPSTAN.
After .the ERROR value is multiplied by appropriate phae LOOP GAIN Kp in each mode and after it passes the phase
compensation filter for stabilization of phase loop, it is added to capstan speed error. Because this value has various gain
in each mode, it drives the Motor by amplifying POWER externally.
Capstan speed control measures the cycle of C.FG which is shaped waveform, outputting from CAPSTAN MOTOR inside
of IC and compares it with reference.
Waveform shaping circuit of C.FG and speed control are as follows.

The chrominance component in the AGC amp, output is filtered out by a LPF and the luminance signal is fed to the YNR
circuit. In the circuit, it is provided a vertical enhancing for the luminance signal.
For the next, high frequency component of the output signal from the YNR circuit is enhanced by the emphasis circuits
(consists of Detail Enhancer, Non-linear Emphasis, and Main Emphasis.), and its output is given from Pin 5.
This signal is fed to the FM modulator through pin 42, and the recording Y-FM signal is obtained from Pin 40.

Fig. 2 The signal flow of the Luminance signal on the PB mode
This signal is passed through the Double Limiter and demodulated to video signal by the Frequency Demodulator.
The Frequency Demodulator output is fed to the YNR circuit block through the Main deemphasis and the LPF.
The circuit including the external CCD (1H delay line) is composed of both functions of the YNR and the drop out
compensation.
The YNR output is fed to the Y/C Mix circuit through the Non-linear de-emphasis, the Double high pass noise canceler
and the Picture control circuit, and then the signal is mixed with the PB chrominance signal and a PB video signal is
obtained from Pin 34 through the Quasi-V/H insertion circuit, the Character insertion circuit and the Video output amplifier.

The flow chart of chrominance signal on the REC mode is shown in Fig. 3.
A recording composite video signal is fed to the AGC circuit from Pin 37, and one of its output signal is passed through a
BPF (fsc: 4.43Mhz) to extract chrominance components from it, then only the chrominance signal is fed to the ACC
amplifier. The gain of ACC amp. is controlled with the DC voltage at Pin 14. The output from ACC amp, is obtained from
Pin 25 which can be used for a PAL/SECAM detection, while it is fed to the main converter through the burst emphasis
(up) circuit.
Also the other output from ACC amp, is fed to the level detector (ACC DET.) through the burst gate amplifier. The output is
smoothed by the external filtering capacitor connected to Pin 14 and the signal is fed back to the ACC amplifier in order to
control the burst level of ACC amp. constant.
Accordingly, the signal level of burst which is passed through the Burst emphasis circuit and the Main converer circuit is
controlled Burst emphasis circuit and the Main converter circuit is controlled constant, and the REC chroma, Signal is
stabilized even if a level of input video signal is fluctuated.
The output from Main converter is fed to the Killer circuit through the LPF.
The Killer detector can give a reliable operation thanks to the application of both systems of the Synchronized detection
(APC killer) and the Peak detection (ACC killer) on the REC mode.
The signal through the killer circuit is obtained from Pin 15 as a REC chroma, output.

Fig. 4 The flow chart of the chrominance signal on the PB mode
The input signal at Pin 15 is fed to the Main converter through the ACC amplifier. And the output from the Main converter
is obtained from Pin 25 through the BPF and the Comb amplifier. After filtering out crosstalk components by an external
comb fitter, the signal is inputtd again at Pin 27, and this signal is fed to the Y/C mixer through the 6 dB amplifier, the BPF,
the PB amplifier, the Burst de-emphasis (down) and the Killer circuit.
However, in case of MESECAM mode, the Main converter output through the BPF is fed to the PB amplifier by bypassing
the Comb amplifier and the Comb filter. In addition, the Killer circuit is switched off on the MESECAM mode.
