SAFETY NOTICE
SAFETY PRECAUTION
1. An isolation transformer should be connected in the power line between the receiver and the AC
line when a service is performed on the primary of the converter tran sformer of the set.
2. Comply with all caution and safety-related notes provided on the cabinet back, inside the cabinet,
on the chassis or the picture tube.
3. When replacing a chassis in the cabinet, always be certain that all the protective devices are
installed properly, such as, control knobs, adjustment covers or shields, barriers, isolation resistorcapacitor networks etc.. Before returning any television to the customer, the service technician
must be sure that it is completely safe to operate without danger of electrical shock.
X-RADIATION PRECAUTION
The primary source of X-RADIATION in television receiver is the picture tube. The picture tube is
specially constructed to limit X-RADIATION emissions. For continued X-RADIATION protection,
the replacement tube must be the same type as the original including suffix letter. Excessive high
voltage may produce potentially hazardous X-RADIATION. To avoid such hazards, the high voltage
must be maintained within specified limit. Refer to this service manual, high voltage adjustment for
specific high voltage limit. If high voltage exceeds specified limits, take necessary corrective action.
Carefully follow the instructions for +B1 volt power supply adjustment, and high voltage check to
maintain the high voltage within the specified limits.
PRODUCT SAFETY NOTICE
Product safety should be considered when a component replacement is made in any area of a receiver.
Components indicated by mark in the parts list and the schematic diagram designate components in
which safety can be of special significance. It is particularly recommended that only parts designated
on the parts list in this manual be used for component replacement designated by mark. No deviations
from resistance wattage or voltage ratings may be made for replacement items designated by mark.

2. Two-None (no picture, no sound)
The failure shows that the set does not display the picture but it has noise wave or blue background or OSD on the screen. This means that the circuits of power supply, horizontal scanning, vertical scanning and video
amplification are normal and they are not considered in the repairing. The failures are mainly in the small signal processing circuits.
Before checking these circuits, a kind of practical test method is introduced. It is called “Signal-input way”. The detail is described a s follow: We ca n use the resistance function of an analog multimeter, connect the red pole
(negative in ohm scope) on the circuit board ground, then touch softly the test point with another pole (black pole) in ohm scope meanwhile observe the reactivity on the output device.
Note: In the TV test, we mainly observe the noise wave on the CRT and listen to the noise voice liking as “Ka…..Ka” from the loudspeakers.

b. No sound
In this kind of failure, first of all we should observe if there is the picture on the CRT. It proves the small signal circuit to work correctly with the picture on the CRT and we only check the sound signal processing and sound
amplification circuit. The repairing method (B1) may be referred without picture. The detail checking and repairing steps are as follow.
Note: Before repairing, assure that the volume is on and the state of set is in “TV”.

3. Only horizontal line in the middle of the screen:
If vertical deflection circuit does not work, this kind of failure will happen. In deflection yoke, there only has horizontal sweeping, the electron beam in the CRT only moves in the horizontal orientation, so form this failure.
(While checking horizontal and vertical deflection circuit’s failure, we have better to use an oscilloscope.)

4. Only vertical line in the middle of the screen
This is a dangerous failure. It probable causes flashover and smoking inside the set. Don’t let your TV wo rk for a long time as this failure appears. Because the electron beam can not move in the horizontal orientation, the
failure should be in the horizontal deflection circuit. We mainly check the open-circuit fault in horizontal deflection circuit. The detail checking and repairing steps are as follow:
5. UOC does not work
In television, remote-control system is similar with the computer system. In theory, it can work if it holds two conditions as follow:
The power supply: In general, it is 5V, the error is not above 10% and the disturbance pulse is as small as possible.
The clock pulse: In TMPA88XX circuit, the clock pulse is generated by pin 6 / pin 7 of N204 and 12M crystal oscillator.
Television’s remote-control system also needs reset circuit that can preset the values in internal register. The circuit around pin 5 of N204 is called auto-re set circuit. If UOC detects errors in resetting, it will come to the state of
program protected.
The detail checking and repairing steps are as follow:
Check Z901, N204
Check N204 Check the voltage on the emitter of V902
Check if there is bad solder between XZ411, and the main board
Check L414, C412, C415, C416 especial in inductive components and connector

6. No OSD (On Screen Display)
This failure is usually cause by the circuit of character generated and located. Most of reasons are that the horizontal and vertical flyback pulse signals do not come to UOC.
We can judge this failure by measuring the wave of the character in an oscilloscope.
The detail checking and repairing steps are as follow:
Check FBT T402, N402

Check the wave on the pin 4 of FBT and N402 pin1
