1. Precautions and Safety Notices

WARNING!

This service information is designed for experience repair technicians only and is not designed for use by the general public.

It does not contain warnings or cautions to advise non-technical individuals of potential dangers in attempting to service

a product.

Products powered by electricity should be serviced or repaired only by experienced professional technicians.

Any attempt to service or repair the product or products dealt within this service information by anyone else

could result in serious injury or death.

1. CAUTION

No modification of any circuit should be attempted. Service work should only be performed after you are thoroughly

familiar with all of the following safety checks and servicing guide lines.

2. SAFETY CHECK

Care should be taken while servicing this CRT display because of the high voltage used in the deflection circuits.

These voltages are exposed in such areas as the associated flyback and yoke circuits.

3. FIRE & SHOCK HAZARD

3-1 Insert an isolation transformer between the CRT display and AC power line before servicing the chassis.

3-2 In servicing pay attention to original lead dress especially in the high voltage circuit. If a short circuit is found,

replace all parts which have been overheated as a result of the short circuit.

3-3 All the protective devices munt be reinstalled per original design.

3-4 Soldering must be inspected for possible cold solder joints, frayed leads, damaged insulation, solder splashes or

sharp solder points. Be certain to remove all foreign material.

4. LEAKAGE CURRENT COLD CHECK

4-1 Unplug the AC cord and connect a jumper between the two prongs on the plug.

4-2 Turn the CRT display power switch “on”.

4-3 Measure the resistance value with an ohmmeter between the jumpered AC plug and each exposed metallic part on

the CRT display such as the metal frame, screwheads, control shafts, etc. When the exposed metallic part has a

return path to the chassis, the reading should be 1.8 megohm minimum.

5. LEAKAGE CURRENT HOT CHECK

5-1 Plug the AC cord directly into the AC outlet. Do not use an isolation transformer during this check.

5-2 Connect a 1500 ohm, 10 watt resistor, paralleled by a 0.15uF capacitor between each exposed metallic part and a

good earth ground (as shown in Fig.1).

5-3 Use an AC voltmeter with 1000 ohm/volt or more sensitivity and measure the AC voltage across the

combination 1500 ohm resistor and 0.15uF capacitor.

h

d

5-4 Move the resistor connection to each exposed metallic part and measure the voltage.

5-5 Reverse the polarity of the AC plug in the AC outlet and repeat the above measurement.

5-6 Voltage measured must not exceed 7.5 volt RMS, from any exposed metallic part to ground A leakage current

tester may be used in the above hot check, in which case any current measured must not exceed 5.0 milliamp. In

the case of a measurement exceeding the 5.0 milliamp value, a rework is required to eliminate the chance of shock

hazard.

Note： High voltage is present when this CRT display is operating. Always discharge the anode of the picture tube to the

display chassis to prevent shock hazard.

4. Circuit Description

4-1 Micro controller and deflection circuit

MICRO Controller

The micro controller(IC101) core is a 80C51 type. The micro clock frequency of 12 Mhz is derived from the Xtal

2

oscillator,which is running at 48MHz. The DDC interface is suitable to handle DDC2 by a modified hardware I

interface .Standard high current ports,3 ADC pouts with voltage inputs and 4 static standard 8 bit DAC outputs (low

interference) and one PWM output for digital control application are implemented. The central processing unit (CPU)

manipulates operands in two memory spaces.These are the 1024byte internal data memory(consisting of 256 bytes

standard RAM and 768 bytes AUX-RAM) and 48K-byte internal program memory . The programmemory of the

SAA4849 consists of 48K bytes ROM.

The SAA4849P provides sync. Processing with full auto sync. Capability, a flexible SMPS block and an extensive

set of geometry control facilities. Further the IC generates the drive waveforms for DC coupled vertical boosters to the

TDA8172.

H/V sync signals processor

The functions of the sync processor include polarity detection, H-SYNC & V-SYNC signals counting, Programmable

SYNC signals output, free running signal generator. Pin52/Pin53 are for the H-SYNC and V-SYNC input. and the

polarity are setting in the positive. When no signal input, the Pin49 will output a 75Hz V-SYNC free run signal. The

Pin18/20will output a 60KHz H-SYNC free run signal. for the monitor testing use.

C-bus

Reset Circuit (pin23)

There are three ways possible to invoke a reset and initialize the SAA4849 micro controller part:

Via power-on reset circuit

Via watchdog timer overflow(only micro controller reset)

Via deflection reset after start up (only micro controller reset)

The reset pin(pin23) is connected to a Schmitt trigger for nose reduction. A reset is accomplished by holding the Reset pin

HIGH.

The x-ray ptotection (pin22) input XRAY provides a voltage detector with a precise voltage input for X-ray

protection .If the input voltage at XRAY exceeds the upper threshold for 150us to 300us,the system is forced to shut down

by switching off vertical,H-and B-drive signals. There are two different ways to handle the system in case of XRAY

occurrence:

1. If the xray latch enable bit UCXRAY [2] was set to “0” during startup the system will shut down without any interference

of the uC. The deflection controller is set to ldle mode. Restart of the system only possible due to seitching power

off/power on.

2. If register bit UCXRAY [2] was set to “1”, micro controller interaction is allowed .If the micro controller doesn’t interrupt

the system, the system will shut down to ldle mode. For any interaction of the micro controller the XRAY occurrence has

to be acknowledged by the micro controller by clearing the bit SY-STATUS [2]. The micro controller take over the control

of the handling via software. The actual xray pin status can be read through bit SY-STATUS [1].

Quartz Oscillator (pin45, pin46)

The quartz oscillator circuit is available on pins XTAL1 (input) and XTAL2 (output) and works together with an

rd

external 48MHz 3

overtone quartz. As a result the quartz oscillator is always running on 48MHz.Other quartz crystal

frequencies than 48 MHz cannot be used. External capacitors on XTAL1 and XTAL2 are not allowed.

B+ Control Function Block

The B+control block of the SAA4849 has the same behaviour as the TDA4856 with adapted threshol voltages. The

2

circuit allows the user to choose the trigger edge of the HDRV signal and the polarity of the output stage via I

C-Bus.

The B+ control function block of the SAA4849 consists of an Operational Transconductance Amplifier (OTA), a

voltage comparator,a flip-flop and a discharge circuit. This configuration allows easy application for different B+ control

concepts.

HPLL

The horizontal part contains a PLL,which works over the full frequency range from 25kHz to 140 kHz.This range can be

2

reduced by a ower and an upper frequency limit(Write Once Registers HPMAX and HPMIN).Via I

C bus the number of

48MHz clock cycles is sent through the register.The slewing speed during mode change is also programmable in a write once

register (HSLEW)

After the clocks for the HPLL are switched on,the HPLL starts with a fixed freerunning frequency of 60 kHz.The

H-drive pulses are not active and the start up procedure is inhibited.The default setting of register bit HCONTROL [0] will

2

cause the HPLL to slew ,not switch.to the freerunning frequency defined in the I

C register HPFREE( the default value is also

60 kHz).Independent on H-syncs which are possibly present.the HPLL will slew to that freerunning frequency.To achieve an

always defined starting point for the startup procedure,this procedure cannot be interrupted.
