Safety instructions, Modifications

2. Safety instructions, Modifications

2.1 Safety instructions

• Safety regulations demand that the set be restored to its original condition and that components identical with the original types be used.

• Safety components are marked by the symbol h

• All ICs and many other semi-conductors are susceptible to electrostatic discharges (ESD). Careless handling during repair may reduce life drastically. When repairing, make sure that you are conneted with the same potential as the mass of the set via a wrist wrap with resistance. Keep components and tools on the same potential.

• A set to be repaired should always be connected to the mains via a suitable isolating transformer.

• Never replace any modules or any other parts while the set is switched on.

• Use plastic instead of metal alignment tools. This in order to prelude short-circuit or to prevent a specific circuit from being rendered unstable.

Engineer's remarks:

2.1.1 Remarks

• The direct voltages and oscillograms ought to be measured relative to the set mass.

• The direct voltages and oscillograms mentioned in the diagrams ought to be measured with a colour bar signal and the picture carrier at 503.25 MHz (C25).

• The oscillograms and direct voltages have been measured in RECORD or PLAY mode.

• The semiconductors, which are mentioned in the circuit diagram and in the parts lists, are fully exchangeable per position with the semiconductors in the set, irrespective of the type designation of these semiconductors.

Special functions of your new video

recorder

Introduction

Your PHILIPS video recorder is not just for recording and playing back VHS cassettes. It also

a whole range of special functions which will make the day-to-day use of your new v

recorder much easier.

Philips has developed a system which produces the best possible playback quality. For old

often-used video cassettes, this system reduces interference. For new or high quality cassette

emphasises the details.

This function allows you to save the playback settings that suit you best. Select your own personalsettings for this type of film you are currently watching.

When you connect your video recorder to your television and plug it into the wall socket,

will be welcomed with a screen menu. All you have to do is follow the instructions in

'intelligent help line' for the next step. Enjoy the automatic TV channel search/save function

the automatic time setting.

You can operate the main functions on your television using your video recorder remote control,even if your television is not a Philips.

This function automatically transfers all the television channel settings onto your video record

Recordings made on your video recorder can be controlled by an external satellite receiver.

Your video recorder can ascertain which channel is currently playing on your television

record from it at the touch of a button.

The precision tape drive from Philips provides short rewind times and automatic tape length

recognition.

Direction for use

Connecting the video recorder

Preparing the remote control for

operation

The remote control and its batteries are packed separately in the original video recorder

packaging. You must install the batteries in the remote control before use - described in the

following section.

1 Take the remote control and the enclosed batteries (2 batteries).

2 Open the remote control's battery compartment and place the

batteries in it as shown in the picture and close the battery

compartment.

The remote control is now ready to use. Its range is approximately 5 meters.

Connecting your video recorder to the TV

set

The necessary cable connections must be made before you can record or playback TV

programmes using your video recorder.

We recommend that you use a scart cable to connect your TV set and video recorder.

What is a scart cable?

The scart or Euro AV cable serves as the universal connector for picture,

sound and control signals. With this type of connection, there is practically no

loss of quality during the picture or sound transfer.

When you install your video recorder for the first time, select one of the following options:

'Connecting with a scart cable'

If your TV set has a scart socket and you are using a scart cable.

'Connecting without a scart cable'

If you do not wish to use a scart cable.

The symbols on your video recorder

display

These symbols can light up on your video recorder display:

This is where the current operating mode is shown as a symbol.LPWhen you have switched on the LP (Long Play) function or when you

play a tape that has been recorded in LP (Long Play).

channel setted on the TV set.

You will find more information on how to switch 'Direct record' on or off in the next section

'Direct record'.

How does Direct Record work?

The video recorder compares the TV channel selected on the TV set with its

stored TV channels via the scart cable. If the same TV channel is found, it

switches the video recorder to the corresponding programme number and

starts recording.

not to affect the process.

Programming a recording (TIMER)

General information

Use programmed recording to automatically start and stop a recording at a later date. The video

recorder will switch to the right programme number and begin recording at the correct time.

With this video recorder, you can pre-programme up to six recordings within a period of one

month.

To make a programmed recording, your video recorder needs to know:

* the date you want to make the recording

* the programme number of the TV channel

* the start and stop time of the recording

* VPS or PDC on or off

This information is saved in a 'TIMER block'.

What is 'VPS/PDC'?

'VPS' (Video Programming System)/ 'PDC' (Programme Delivery Control) are

used to control the start and duration of TV channel recordings. If a TV

programme starts earlier or ends later than was scheduled, the video recorder

will then turn on and off and the correct time.

What do I need to know about 'VPS/PDC'?

Usually the start time is the same as the VPS or PDC time. But if your TV

guide gives a VPS or PDC time which is different from the programme's start

time, e.g. '20.15 (VPS/PDC 20.14)', you must enter the VPS/PDC time

'20.14' exact to the minute as the start time.

If you want to programme a time that is different from the VPS or PDC time,

you must switch off VPS or PDC.

Only one TV program of a TV channel can be controlled using 'VPS/PDC' at a

time. If you want to record two or more TV programmes on a TV channel

using 'VPS/PDC', you will need to programme these as two separate

recordings.

aMy Set Top Box does not switch to programme number 12

b Please check that you entered the correct code number. Repeat step 6 .

b Also try other code numbers.

b Please make sure that the IR electronic eye on the Set Top Box is not

blocked.

b You may wish to reposition the SAT mouse (repeat steps 1 and 6 ).

8 Confirm the correct code number with OK .

9 Affix the satellite control to the Set Top Box using the adhesive strip

on the bottom of the satellite control.

0 To end, press the MENU button.

The satellite control has now been successfully installed.

Further information regarding the use of the satellite control for programmed recordings is

included in chapter 'Programming a recording (TIMER)'.

Step 10: Operation without drive - dummy mode

Before activating this mode with the SELECT key, the recorder must be in the EJECT position.

Enter the mode by pressing the SELECT key. The motors are then switched off and the sensors will be ignored by the deck microprocessor. The drive can now be dismantled from the motherboard (see dismantling instructions). Only install drive if recorder is disconnected from mains. For signal tracking, the recorder can be set to all drive conditions, i.e. signal electronics, audio and IO processing are switched to the respective operating mode.

Service modes, Repair tips

In case of an invalid entry (value >255) the activation of the OK key causes the content of the last stored option to be displayed and OK does not appear in the display.

Depending on the model, some bits are software or default protected and cannot be changed by an entry. In this case, the display shows OK, but the display returns to the default value.

Step 98: Display Test

By pressing the SELECT key whilst step 98 is flashing, all segments of the display are illuminated.

The step is exited by pressing SELECT again.

Step 40: Option code input

If a new EEPROM is installed in the course of repairs, it must be initialised. By pressing the SELECT key whilst step 40 is flashing, the decimal option A appears in the display.

By entering a 3-digit decimal code, the correct features are set.

5.3 Repair tips

5.3.1 Replacement procedure for leadless components (chip)

The following procedures are recommended for replacing leadless components used in this unit.

1. Preparation for replacement

a. Soldering iron

Use a pencil-type soldering iron that uses less than 30W

b. Solder

Use Eutectic solder (Tin 63%, Lead 37%) c. Soldering time Maximum 4 seconds.

Note:

• Leadless components must not be re-used after removal.

• Excessive mechanical stress and rubbing of the

component electrode must be avoided.

2. Removing the leadless components

Grasp the leadless component body with tweezers and alternately apply heat to both electrodes. When the solder on both electrodes has melted, remove leadless component with a twisting motion.

Note:

• Do not attempt to lift the component off the board until the

component is completely disconnected from the board

with a twisting motion.

• Be careful not to break the copper foil on the printed

circuit board.

b. Using tweezers press down the part and solder both electrodes as shown below.

) /

fnom

Determining the correction value for Step 53:

Correction value = Deviation / 0.763 + 128 (round off to whole number)

The calculated correction value must be between 0 and 255 (change quartz otherwise), and must be entered in Step 53 and saved. This step can either be exited by performing a main power source reset, after which the service program must be entered again or by pressing any key on the set, before step 53 can be entered.

Example:

=8191.97Hz f

mess

Deviation = 1x10

=8192.00Hz

nom

x (8191.97 - 8192.00) / 8192.00 = -3.662

Correction value = -3.662 / 0.763 + 128 = 123.20 = 123

8.8.2 Inputing the clock correction

Before carrying out step 53, the correction value must be established in step 99.

Electrical alignments

GB 95VR120 8.

By pressing the SELECT key whilst step 53 is flashing, the display shows, for instance (128 is the default value of an empty EEPROM):

Using the numerical keys of the remote control, the established correction value from Step 99 is entered as a 3digit number (value must be between 0 and 255).

After pressing the OK key on the remote control, the entered code is stored, the display shows OK for approx. 3 seconds and then the stored value in decimal format.

In case of an invalid entry (value >255), the activation of the OK key causes the content of the last stored value to be displayed and OK does not appear in the display. To leave the step press Select.

9.1 Switched-mode power supply PS (PS Part)

9.1.1 Technical data:

Mains voltage : 195-264 Vrms Maximum output : 15W / 40W

(continuous /

maximum output) Operating frequency : 40 kHz Efficiency : approx. 75 % at

maximum output

Six different direct voltages are supplied on the power supply outputs.

9.1.2 Functional principle:

This power supply functions in a similar way to a blocking oscillator. In the supply voltage part [1300 to 2318], the mains voltage is rectified and buffered in the capacitor [2318]. From this direct voltage [2318] energy is transferred into the transformer [5301, pins 1-3] during the conductive phase of the switching transistor [7302] and is stored there as magnetic energy. This energy is passed to the secondary outputs on the power supply in the in the blocking phase of the switching transistor [7302]. With the switch-on time of the switching transistor [7302], the energy transferred in every cycle is regulated in such a way that the output voltages remain constant regardless of changes in the load or input voltages. The power transistor is activated using the integrated switch [7303] ( see figure 9-1 ).

9.1.3 Supply voltage part

The supply voltage part extends from the mains socket [1300] to the capacitor [2318]. Using the diodes [6310, 6311, 6312 and 6313] the a.c. supply voltage is rectified and buffered using the capacitor [2318]. The line reactor [5305] and capacitor [2316] create a filter to keep interference arising in the power supply away from the mains. Components [1302], [3326] and [3323] protect the power supply against short-term overvoltages in the mains, e.g. caused by indirect effects from lightning.

9.1.4 Start-up with Mains-on:

Following connection to the mains, the capacitor [2310] is loaded via the start-up resistor [3318] and a current source between pin 8 and pin 6 on the IC [7303]. Once the voltage on [2310] and therefore the supply voltage Vcc on the IC [7303] has reached approx. 13V, the IC starts up and issues pulses to its output on pin 5. These pulses are used to control the gate on the power transistor [7302] ( see figure 9-2 ). The frequency has a fixed setting in the IC (approx. 40 kHz). The current input on the IC is approx. 5 mA in normal mode. If Vcc drops to below approx. 10V (e.g. with power limitation) or if Vcc exceeds around 15V (interruption of the control loop), the output on the IC [7303, pin 5] is blocked. All output voltages on the power supply, and therefore also Vcc, decrease. Once Vcc has dropped to below approx. 6.5V, a new start-up cycle begins.

Circuit descriptions and List of abbreviations

.1.5 Normal mode:

With the power supply in normal mode, the periodic sequences in the circuit are divided primarily into the conductive and blocking phase of the switching transistor [7302]. During the conductive phase of the switching transistor [7302], current flows from the rectified mains voltage to the capacitor [2318] through the primary coil on the transformer [5301, pins 1-3], the transistor [7302] and resistors [3314, 3331] to earth ( see figure 9-1 ). The positive voltage on pin 1 of the transformer [5301] can be assumed to be constant for a switching cycle. The current in the primary coil on the transformer [5301] increases linearly in the pattern of U=L*di/dt. A magnetic field representing a certain volume of the primary current is formed inside the transformer. In this phase, the voltages on the secondary coils are polarised in such a way that the diodes [6300, 6301, 6306, 6308 and 6309] block. From the controller on [7301], a current is supplied to the CTRL input on the IC [pin 3, 7303] via optocoupler [7300]. Once the switch-on time for the switching transistor [7302] has been reached, which corresponds to the current supplied on the CTRL input, the switching transistor is switched off.

Once the switching transs been switched off, the blocking phase begins. No more energy will be transferred into the transformer. The inductivity of the transformer will still attempt to maintain the current which has flowed through it (U=L*di/dt) at a constant level. As the primary current circuit is interrupted by the shut-off switching transistor [7302], the current will flow through the secondary coils. The polarity of the voltages on the transformer is reversed, which means that the diodes [6300, 6301, 6306, 6308 and 6309] become conductive and current flows into the capacitors [2301, 2305, 2309, 2311 and 2312] and the load. This current is also ramp-shaped (di/dt negative, therefore decreasing). The control adjustment for the switched-mode power supply is made by changing the conductive phase of the switching transistor ( see figure 9-2 ), so that either more or less energy is transferred from the rectified mains voltage to [2318] in the transformer. The control information is provided by the control element [7301]. This element compares the 5V output voltage via the voltage dividers [3300, 3306, 3336] with an internal 2.5V reference voltage. The output voltage from [7301] passes via an optocoupler [7300] (for the metallic isolation of the primary and secondary parts) as the current value to pin 3 on the IC [7303]. The switch-on time for the switching transistor [7302] is inversely proportional to the value of this current.

.1.6 Overload, power limitation, burst mode:

followed by another start-up attempt ( Burst Mode ). The amount of power taken up from the mains in burst mode is low.

9.1.7 Standby mode:

In the ‘Standby‘ operating mode on the device, the ’STBY‘ control line is used to shut off the output voltages 14AL, 5VA and 5VD on the power supply to minimise the amount of power taken up from the mains. The supply to the display heating can also be switched off using the ‘I1WSTBY‘ control line. The power supply itself will continue to function continuously in the ‘Standby‘ operating mode with a switching frequency of 40kHz.

9.2 Operating unit DC (DC part)

Dmax

point of reversal

With an increasing load on one or more power supply outputs, the switch-on time for the power transistor [7302] also increases, and thus also the peak value of the deltashaped current through this power transistor. The equivalent voltage circuit for this current profile is passed from resistors [3314] and [3331] via [3312] and [3347] to pin 2 on the IC [7305]. If the voltage on pin 2 reaches 1V in one switching cycle, the conductive phase of the switching transistor is ended immediately. This check is made in each individual switching cycle. This process ensures that no more than approx. 48W can be taken out of the mains (= power limitation). If the power supply reaches the power limit, the output voltages and the supply voltage Vcc on pin 6 of the IC [7303] will be reduced following further loading. If Vcc is less than approx. 10V at any point during this process, the output on the IC [7303, pin 5] is blocked. All output voltages and Vcc are reduced. Once Vcc has dropped to below approx. 6.5V, a new start-up cycle begins. If the overload status or shortcircuit remains, the power limitation will be activated immediately and the voltages will continue to be reduced,

• Back-up mode

In normal operation, the P is operated in dual-clock mode, i.e. both quartzes [1170, 1171] oscillate. The time is derived from the slow quartz [1170] (32.768 kHz), and the fast quartz [1171] (16MHz) is used to generate the system clock frequency. In case of a mains failure (back-up mode) the P is not reset, but instead the mains failure is registered by the IPOR interrupt 3 [7899-B] (pin 67) and the P is moved into “Sleep mode” (low pow er consumption). The 16MHz quartz is turned off and the 32kHz quartz is then used as the clock and system clock frequency. The operating voltage for the AIO is buffered by a back-up cell [pos. 2174, 2172]. A diode [6171] prevents this gold capacity from discharging.

9.2.1 Evaluation of the keyboard matrix

There are 12 different keys. Each key function is assigned a fixed voltage value. This value is decoded using an analogue/digital (A/D) port (7899-B, pin 56). Each mechanical key position on the printed board can adopt any key function via a coding resistor. Pressing keys simultaneously may lead to undesired functions!

9.2.2 IR receiver and signal evaluation

The IR receiver [6170] includes a selective, controlled amplifier in addition to a photo-diode. The photo-diode changes the received transmission (approx. 940nm) in electrical pulses, which are then amplified and demodulated. On the output of the IR receiver [7220] a level lift 0V/5V pulse sequence, which corresponds to the envelope curve of the received IR remote control command, can be measured. This pulse sequence is input into the controller for further signal evaluation via input IRR [7899-B, pin 46].

9.2.3 Activation and function of the VFD display

In principle, the VFD display [7170] is a tube triode in which the heating filaments in the tube serve as cathodes (F+,F-). The 7 grids (G1 - G7) are activated via PC2 - PC7, PD0 on the controller, and the 16 anodes (P1 - P16) are controlled via ports PE0 - PE7, PF0 - PF7, PC0, PC1 on the controller, each with a positive potential compared to the cathode. The grids and anodes (digits and symbols to be displayed) are activated in the time-multiplex procedure, voltage lift 5V/

-18V. A dimmer function is generated using pulse-width modulation of the grid control signals. At maximum display brightness, the pulse width for each grid is 2.16 ms. It can be reduced, controlled using software, which reduces the visual brightness of the VFD display accordingly. A digit or symbol is only illuminated if the corresponding anode and the surrounding grid are switched simultaneously to 5V for a certain time within a scanning period. The electrons emitted from the cathode are accelerated by the positively charged grid and hit the luminous layer of the anode which is also positively charged. During the remainder of the scanning period, the corresponding grid and parts of the anode are at -18V, due to the internal pull-down resistors in the controller. This potential is still lower than the average cathode potential of approx. -15V, prevents the acceleration of electrons, thus causing the relevant grid and anode segments to go dark. The heating direct voltage of the display (U = 3.5V) is supplied from the power supply via lines HELO or HEHI to pins F+ and F- to the VFD display. Resistors [3070] and [3071] restrict F- to approx. -15V.

9.3.1 Analogue interface to the C:

The following analogue levels are supplied to the µ C’s internal analogue/digital (A/D) converter:

• TAE/TAS Tape End / Tape Start Detection

• TRIV Tracking Information Video

• TRIA Tracking Information Audio

• AGC Automatic Gain Control

• AFC Automatic Frequency Control

• 8SC1/2 Pin 8 Scart1 or Scart2 switching voltage

• Key-in Keypad evaluation

9.3.2 Tape end - LED control :

The LED current is switched using transistor [7804]. The ON time is approx. 1 msec and the OFF time approx. 12 msec during playback and 1msec to 5.5msec during the winding functions. The LED current is typically 150 mA. In order to prevent interference from the relatively high pulsed current ‘spreading’ through the entire unit, the LED is fed from the 14VM1, and filtered by 2 resistors [3800, 3805] with 10R each and a 220µF electrolytic capacitor [2803].

9.3.3 CMT detection (video detection with CSYNC)

This has been extended due to identification problems with weak transmission signals and video signals not conforming

to the STANDARD (common channel interference). The CSYNC line is supplied to the µP [7899-B] on pin 50. A hardware integration [7807,7808,7809] of the video pulse

compensates the interference generated by the common channels and weak signals.

.3.4 EE-PROM

The EE-PROM [7818] is a non-volatile memory which can be erased and written to electrically. (Data remains even if the operating voltage fails). Data specific to the device such as the X distance, head changeover position, preset stations, optional bytes etc. is stored in the EE-PROM [7818]. The data is accessed by the µP via the I

C bus.

.3.5 Easy link (P50)

For the communication between the TV set, video recorder and the peripheral devices, a bi-directional single-wire bus is used, which runs via pin 10 to scart socket 1. The output signal is generated on pin 84 of the µC [7899-B], pin 68 is the signal input.

.3.6 Shuttle

The shuttle is connected to the motherboard on plug pos.1982. It is a binary coded rotary switch with a rotation angle of +/- 70 degrees and 16 switch positions. These are input and evaluated via four lines (shuttle b1 - shuttle b4) to the input ports P24 - P27 [7899B pins 2-5].

this step-up. This creates an aperiodic transient response in the resonance. Beyond the resonance frequency, there is an adjustment in terms of a steep fall in the frequency transmission characteristic. This effectively suppresses highfrequency pick-ups. The CTL head signal amplitude in standard play is around 1mVp (typ.) which means that the amplification for the playback amplifier must be correspondingly high. To avoid offset problems, a 100 F electrolytic capacitor [2490] is fitted in the negative feedback branch for DC decoupling. The polarity of the playback amplifier can be changed using the Video Index Search System (VISS) voltage. This is the only way in which the P can write a VISS mark on the tape without spikes. The Write/Read (W/R) signal is used to switch over between record and playback: W = “H“, R = “L“.

9.4.2 Power on reset (POR) generator

The POR generator contained in the M63100FP [7463] requires only one external capacitor [2477], which specifies the length of the POR pulse. For 33 nF, t

POR

The response threshold of the reset circuit is between 4.5 and 4.8 V. Supply fluctuations which are shorter than tPOR/ 100 area and which do not fall below 4.0 V, do not trigger the POR. The P is reset using the inverted POR.

is approx. 30ms.

.3.7 Satmouse

For activating a sat-receiver via an external infrared electronic transmission unit (Satmouse) a bi-directional data line, a short-circuit proof +5V and earth are provided via a 3pin 3.5mm jack [1941]. The +5V is limited to approx. 140 mA using a current limiting switch [7812 and peripherals].

9.4 Deck electronics DE (DE part)

The deck interface IC MP63100FP [7463] contains the following functional groups:

• CTL stage (tape synchronisation)

• Sensor interface

• Power on reset

• Head drum motor driver

• Loading motor driver

• Capstan motor control

.4.1 CTL stage

The IC M63100FP [7463] contains a read/write stage for the CTL track with the option of overwriting an existing CTL track without any interference. The playback stage is fitted with a “digital” five-stage AGC. This logic circuit identifies the size of the output signal supplied by the CTL head, and then selects the best amplification ratio in the playback stage using comparators. The CTL head voltage can therefore vary greatly, if V

is great. The slowest tape speed is in LP mode. The

min

fastest speed is adjusted during rewind. To ensure that the duty cycle in the tape sync is always reproduced correctly in the conditions mentioned above (important for detecting VISS marks), the amplifier must not be overdriven. The five-stage AGC alone cannot cover the large dynamic range of the input voltage. The amplifier is therefore also equipped with a low pass characteristic (fg = 3kHz typ.; internal). In parallel with the CTL head is the RC cell comprising capacitor [2479] and resistor [3471]. The capacitor [2479], together with the CTL head inductivity, causes a resonance step-up at around 10 kHz and the resistor [3471] suppresses

max

The four comparators in the M63100FP [7463] are used to convert sensor signals to the logic level. The outputs are overload protected by a current limiter and thermal overload protection. Only the non-inverting input on each comparator is accessible from the outside. The other inputs are connected to an internal reference of 2.5V. The fixed hysteresis of the comparators of approx. 18 mV is also located internally.

The comparators are connected as follows:

Comparator 1: In = FTA, pin 39; Out = FTAD, pin 34: FTA = threading tachometer. This signal comes from a forked light barrier in the deck. An infra-red light beam is interrupted by a 4-blade impeller (butterfly). The output amplitude for the light barriers should be less than 2V for the low level and greater than 3V in the high level to ensure a correct evaluation process. An additional hysteresis is created with a resistor [3476]. For unit versions <1W and FOME the external operation amplifier [7530B] is used to reduce the power consumption in <1W mode.

Comparator 2: In = WTR, pin 38; Out = WTRD, pin 33: WTR = Winding tachometer right, from a reflection photoelectric barrier. The level is the same as for the FTA.

Comparator 3: In = WTL, pin 37; Out = WTLD, pin 31 : WTL = Winding tachometer left, from a reflection photoelectric barrier. The level is the same as for the FTA.
