CAUTION: Before servicing the chassis, read the “Safely Precaution”.“X -Ray radiation Precaution” and “Product Safety Notice” in this manual.

X-RAY RADIATION PRECAUTION1. Excessive high voltage can produce potentially hazardous X-RAY RADIATION. To

Avoid such hazards the high voltage must be specified limit. The normal value of thehigh voltage of this receiver is 24.5KV +/-2KV under 230V AC power source. Thehigh voltage must not exceed 27KV.

2. Each time a receiver requires servicing the high voltage should be checked followingthe HIGH VOLTAGE CHECK procedure in this manual. It is recommended thereading of the high voltage be recorded as a part of the service record. It isimportant to use an accurate and reliable high voltage meter.

3. The primary source of X -RAY RADIATION in this TV receiver is the picture tube. For

continued X-RAY RADIATION protection, the replacement tube must be exactly thesame type tube as used in this TV receiver.

4. Some parts in this receiver have special safety-related characteristics for X-RAYRADIATION protection. For continued safety, parts replacement should beundertaken only after referring the PRODUCT SAFETY NOTICE below.

SAFETY PRECAUTION

WARNING: Service should not be attempted by anyone unfamiliar with the necessary Precautions on this receiver.The following are the necessary precautions to be observed before servicing thischassis.1. Since the power supply circuit of this receiver is directly connected to the AC

power line. An isolation transformer should be used during any dynamic service toavoid possible shock hazard.

2. Always discharge the picture tube anode to the CRT conductive coating beforehandling the picture tube. The picture tube is highly evacuated and if broken, glassfragments will be violently expelled. Use shatterproof goggles and keep picture tubeaway from the unprotected body while handling.

3. When replacing a chassis in the cabinet, always be certain that all the protectivedevices are put back in place, such as: nonmetallic control; knobs, insulating covers,shields, isolation resistor-capacitor, network, etc.

4. When replacing parts or circuit boards, disconnect the power cord.5. When replacing a high voltage resistor (metal oxide resistor) on circuit hoard,

keep the resistor APP. 10mm(1/2 in.) away from circuit board.6. Connection wires must be kept away from components with high voltage or high

temperature.7. If any fuse in this TV receiver is blown, replace it with the FUSE specified in the

chassis parts list.8. The receiver is designed to operate with 230V(50Hz) AC mains.

PRODUCT SAFERY NOTICE

Many electrical and mechanical parts in this chassis have special safety-relatedcharacteristics are often passed unnoticed by a visual inspection and the X-RAYRADIATON protection afforded by them cannot necessarily be obtained by usingreplacement components rated for higher voltage. The use of substitute replacementparts that do not have the same safety characteristics as specified in the parts list maycreate shock, fire, X-RAY RADIATION or other hazards.

GENERAL ADJUSTMENT

AUTOMATIC DEGAUSSINGAn automatic degaussing coil is attached around the picture tube, degaussing the tubeproperly in about one second after the set is switched on. If the receiver is moved orfaced on a different direction, the power must be switched off at least 15 minutes inorder that the automatic degaussing circuit operated properly. External degaussing isnecessary if the automatic degassing proves ineffective after the set is moved.

B+ ADJUSTMENT

CAUTION: To avoid X-ray hazards and result in a nominal display width, B+ voltagemust be set in the scale of 108.0V+/-0.5V.

1. Make sure the AC power supply is 230V, 50Hz.2. Switch on the TV receiver, tune in an active channel.3. Measure the voltage between C641 on Main P.C. Board by DC voltmeter.4. Set contrast, brightness, color to maximum.5. Adjust VR631 on Main P. C. Board for B+108.0V+/-0.5V voltage reading.

HIGH VOLTAGE CHECK

CAUTION: There is no high voltage adjustment in this chassis, B+108V voltagedirectly relates to the high voltage. The high voltage does not exceed 27KV under anyconditions.1. Connect an accurate high voltage meter to the second anode cap of the picture

tube.2. Turn on the receiver, set brightness and contrast to minimum (Zero beam current).3. Make sure the high voltage does not exceed 27KV.4. NO matter whether the luminance, contrast and chrominance controls are set to

maximum or minimum, the high voltage must be kept under 27KV.

FOCUSING

Receive a TV test pattern signal; adjust controls for optimum picture. Adjust FocusControl for a well-defined, sharpest display in the center area of the screen.

ADJUSTMENT AND SERVICING THE CHASSISSERVICE MODE

To enter the service mode, a special remote control which contains an additionalSERVICE key must be used. See the illustration. Press the ‘SERVICE’ key on remotecontrol, TV will display service menu as following table 1 line by line. To select theparameter by using the ‘P+/P-’ keys. To adjust the selected parameter by using the‘V+/V-’ keys. To quit the service mode, press the ‘P.P.’ key on remote control when inthe service mode.

For CPUs with English, French, German, Polish or English, French, German, Turkish,

Please refer to the setting as below.1. If OPTION 5 = 00, then the TEXT languages like "ENGLISH, FRENCH, SWEDISH,TURKISH, GERMAN, PORTUGUESE, ITALIAN, RUMANIAN " can be decoded.2. If OPTION 5 = 02, then the TEXT languages like "POLISH, FRENCH, ESTONIAN,CZECH, GERMAN, SERBIAN, LETTISH, RUMANIAN " can be decoded.3. If OPTION 5 = 04, then the TEXT languages like "ENGLISH, FRENCH, SWEDISH,CZECH, GERMAN, PORTUGUESE, LETTISH, RUMANIAN " can be decoded.4. If OPTION 5 = 06, then the TEXT languages ENGLISH, FRENCH, SWEDISH, TURKISH,GERMAN, PORTUGUESE, LETTISH, RUMANIAN can be decoded.B. For coming new OTP/CPU with English, Russian, Czech, Polish, the setting of the OPTION5 will be changed as below.1. If OPTION 5 = 00, then the TEXT languages like "ENGLISH, FRENCH, SWEDISH,CZECH, GERMAN, PORTUGUESE, ITALIAN, RUMANIAN " can be decoded.2.

If OPTION 5 = 06, then the TEXT languages like "POLISH, RUSSIAN, SWEDISH,CZECH, GERMAN, PORTUGUESE, ITALIAN, RUMANIAN can be decoded.Normally, it is supposed not to set OPTION 5 = 01. If you set the OPTION 5 = 01, then the fontcan be switched by press key MENU on remote control in TEXT mode for TV3K. If you setOPTION 5 = 00, 02, 04, 06, then there is no any activity while press MENU in TEXT mode.Please check.

A.F.C. ADJUSTMENTRemoving any R.F. signal source and prevent any stray signal source from enteringthe tuner by shorting the tuner input inner contact to the out screen.Inject the 38.9 MHZ carrier into the tuner IF output pin (pin 11).Select the parameter‘VCO Coarse’ in the service mode (see Table 2).The ‘VCO Status…’will appear on thescreen. Then press the ‘AV’ key on remote control, the CPU will adjust automaticallyuntil the ‘VCO Status OK’ appears on the screen. If this can not be achieved, i.e. thereis no any pattern on the screen, please adjust the T201 first until a stable pattern

appears on the screen. And then press the ‘AV’ key on remote control. The CPU willadjust automatically once again until the ‘VCO Status OK’ appears on the screen.

GEOMETRYTo adjust the picture position and vertical size, select the appropriate parameter in the servicemode and adjust as necessary. Please see table 2.
