SAFETY INSTRUCTIONS AND MAINTENANCE
WARNING: BEFORE SERVICING THIS CHASSIS, READ THE X-RAY RADIATION PRECAUTION ,
SAFETY PRECAUTION AND PRODUCT SAFETY NOTICE INSTRUCTIONS-BELOW.
X-RAY RADIATION PRECAUTION
1. The EHT must be checked every time the receiver is serviced to ensure that the CRT does not emit
X-ray radiation as result of excessive EHT voltage. The nominal EHT for this receiver is 29KV (for
25”TV) or 30KV (for 29”TV) at zero beam current (minimum brightness) operating at AC 120V. The
maximum EHT voltage permissible in any operating circumstances must not exceed 32KV (for
25”TV) or 33KV (for 29”TV). When checking the EHT, use the High Voltage Check procedure in this
manual using an accurate EHT voltmeter.
2. The only source of X-RAY radiation in this receiver is the CRT. To prevent X-ray radiation, the
replacement CRT must be identical to the original fitted as specified in the Parts List.
3. Some components used in this receiver have safety related characteristics preventing the CRT
from emitting X-ray radiation. For continued safety, replacement component should be made after
referring the PRODUCT SAFETY NOTICE below.
SAFETY PRECAUTION
1. The receiver has a nominal working EHT voltage of 29KV (for 25”TV) or 30KV (for 29”TV). Extreme
caution should be exercised when working on the receiver with the back removed.
1)
Do not attempt to service this receiver if you are not conversant with the precautions and procedures
for working on high voltage equipment.
2) When handling or working on the CRT, always discharge the anode to the receiver chassis before
removing the anode cap in case of electric shock.
3) The CRT, if broken, will violently expel glass fragments. Use shatterproof goggles and take extreme
care while handling.
4) Do not hold the CRT by the neck as this is a very dangerous practice.
2. It is essential that to maintain the safety of the customer all power cord forms be replaced exactly
as supplied from factory.
3. Voltage exists between the hot and cold ground when the TV is in operation. Install a separation
transformer during repairing or connecting to any testing equipment for the sake of safety. The
power of the separation transformer should exceed the rated overall power.
4. Replace blown fuses within the receiver with the fuse specified in the parts list.
5. When replacing wires or components to terminals or tags, wind the leads around the terminal
before soldering. When replacing safety components identified by the international hazard symbols
on the circuit diagram and parts list, it must be the company-approved type and must be mounted
as the original.
6. Keep wires away from high temperature components.

2. General Description
The various versions of the TDA 884X/5X series are I
2
processors which are intended to be applied in PAL, NTSC, PAL/NTSC and multi-standard television receivers. The N2 version is pin and application compatible with the N1 version, however, a new feature has been added which makes the N2 more attractive. The IF PLL demodulator has been replaced by an alignment-free IF PLL demodulator with internal VCO (no tuned circuit required). The setting of the various frequencies (33.4, 33.9, 38, 38.9, 45.75 and 58.75 MHz) can be made via the I
2
C-bus. Because of this difference the N2 version is compatible with the N1, however, N1 devices cannot be used in an optimised N2 application. Functionally the IC series is split up in 3 categories, viz:
·Versions intended to be used in economy TV
receivers with all basic functions (envelope: S-DIP 56 and QFP 64)
·Versions with additional features like E-W
geometry control, H-V zoom function and YUV interface which are intended for TV receivers with 110° picture tubes (envelope: S-DIP 56)
·Versions which have in addition a second
RGB input with saturation control and a second CVBS output (envelope: QFP 64) The various type numbers are given in the table below.

The Series STR-G5653/F6654 is specifically designed to satisfy the requirements for increased
integration and reliability in off-line quasi-resonant flyback converters. The series incorporates a
high-precise error amplifying control and drive circuit with discrete avalanche-rated power MOSFET,
featuring fewer external components, small-size and standard power supply.
Covering the power range from below 25 watts up to 300 watts for 100/115/230 VAC inputs, and up to
150 watts for 85 to 265 VAC universal input, these devices can be used in a range of applications,
from battery chargers and set top boxes, to televisions, monitors, and industrial power supply units.
Cycle-by-cycle current limiting, under-voltage lockout with hysteresis, over-voltage protection, and
thermal shutdown protects the power supply during the normal overload and fault conditions.
Low-current startup and a low-power standby mode selected from the secondary circuit completes a
comprehensive suite of features. The series is provided in a five-pin overmolded SIP style package,

ADJUSTMENTS
Set-up Adjustments
The following adjustments should be made when a complete realignment is required or a new CRT is
installed. Perform the adjustments in order as follows.
1. Colour purity
2. Convergence
3. White Balance
Note:
The purity/convergence magnet assembly and rubber wedges need mechanical positioning. Refer to
Fig. 18.
1. Colour Purity Adjustment
Note:
Before attempting any purity adjustment, the TV should be operated for at least 15 minutes.
1) Demagnetize the CRT and cabinet using a degaussing coil.
2) Set the brightness and contrast to maximum.
3) Receive the green raster test pattern.
4) Loosen the clamp screw holding the deflection yoke and slide it backward or forward to display
vertical green belt (zone) on the screen.
5) Remove the rubber wedge.
6) Rotate and spread the tabs of the purity magnet around the neck of the CRT until the green belt is on
the center of the screen.
7) Slowly move the deflection yoke forward or backward until a uniform green screen is obtained.
Tighten the clamp screw of the yoke temporarily.
8) Check purity of the red and blue raster.

2. Convergence Adjustment
Note:
Before attempting any convergence adjustment, the TV should be operated for at least 15 minutes.
Center convergence adjustment
1) Receive the crosshatch test pattern.
2) Set the brightness and contrast properly.
3) Adjust two tabs of the 4-pole magnet to change the angle between them and red and blue vertical
lines are superimposed on the center area of the screen.
4) Turn both tabs at the same time keeping the angle constant to superimpose red and blue horizontal
lines on the center of the screen.
5) Adjust two tabs of 6-pole magnet to superimpose red/blue line and green line. Adjusting the angle
affects the vertical lines and rotating both magnets affects the horizontal lines.
6) Repeat steps 3) 5) keeping in mind red, green and blue movement. 4-pole magnet and 6-pole
magnet interact each other, resulting in complicating and dot movement.
Circumference convergence adjustment
1) Loosen the clamping screw of the defection yoke slightly to allow it to tilt.
2) Temporarily put a wedge as shown in Fig.18. (Do not remove cover paper on adhesive part of the
wedge.)
3) Tilt front of the deflection yoke up or down to obtain better convergence in circumference.
Push the mounted wedge into the space between the CRT and yoke to fix the yoke temporarily.
4) Put other wedge into bottom space and remove the cover paper to stick.
5) Tilt front of the deflection yoke right or left to obtain better convergence in circumference.
6) Keep the deflection yoke position and put another wedge in either upper space. Remove cover paper
and stick the wedge on the CRT to fix the yoke.
7) Detach the temporarily mounted wedge and put it in another upper space. Stick it on the CRT to fix
the yoke.
8) After fixing three wedges, recheck overall convergence.
Tighten the screw firmly to fix the yoke and check if the yoke is fixed.

9) Stick three adhesive tapes on wedges as shown in Fig. 18.

Circuit Adjustments
1. General Description
All adjustments are thoroughly checked and corrected before the TV outgoing. Therefore the TV
should operate normally and deliver proper colour pictures upon installation. However, several
minor adjustments may be required depending on the particular location where the TV is operated.
This TV is shipped completely in carton. Carefully take out the TV from the carton and remove all
packing materials. Connect the power cord into a 120V AC, 60Hz two-pin power outlet. Turn on the
TV. Check and adjust all the customer controls such as brightness, contrast and colour to obtain
natural colour pictures.
2. Automatic Degaussing
A degaussing coil is mounted around the CRT so that external degaussing after moving the TV is
generally unnecessary, providing it is properly degaussed upon installation. The degaussing coil
operates in about 1 second after power on. If the set is moved or faced to a different direction, the
power switch must be switched off for a few minutes in order that the automatic degaussing circuit
operates properly. Should the chassis or parts of the cabinet become magnetized to cause poor
colour purity, use an external-degaussing coil. Slowly move the degaussing coil around the screen,
the sides and front of the TV and slowly withdraw the coil to a distance of about 2m before unplug it.
If colour shading still exists, perform the Colour Purity Adjustment and Convergence Adjustment
procedures.
34
Page 37
3. Supply Voltage Adjustment
Caution: +B voltage has close relation to high voltage. To avoid X-ray radiation, +B voltage should be
+145V.
1) Set R801 to the mechanical center and AC power supply to 120±2V.
2) Connect a digital voltmeter to two pins of C838, and then turn on the TV.
3) Receive Philips test pattern signals.
4) Make the voltmeter read 145±0.5V.
4.High Voltage Inspection
Caution: No high voltage adjustment should be done in the chassis.
1) Connect a precise high voltmeter to the second anode of the CRT.
2) Turn on the TV and set the brightness and contrast to minimum (i.e. set beam current of the CRT
to zero).
3) The high voltage tested should be 29±0.5KV(for 25” TV) or 30±0.5KV(for 29” TV)
4) Set the brightness to minimum or maximum, and ensure high voltage not beyond limitation of
30KV (For 25” TV) or 33KV (For 29” TV) in any case.
5. Focus Adjustment
1) Use the remote control to set the contrast to maximum and the brightness, chroma to medium.
2) Set H. V. lines near Philips pattern center to thinnest with the FCB on the FBT. After finishing
adjustment, ensure that no poor focusing exists near the center or around of the frame.
