Warning 1. Servicing of SMDs (Surface Mounted Devices) All ICs and many other semi-conductors are susceptible to electrostatic discharges (ESD). Careless handling during repair can reduce life drastically. When repairing, make sure that you are connected with the same potential as the mass of the unit via a wrist wrap with resistance. Keep components and tools also at the same potential ! 1.1 General cautions on handling and storage - Oxidation on the terminals of SMDs results in poor soldering. Do not handle SMDs with bare hands. - Avoid using storage places that are sensitive to oxidation such as places with sulphur or chlorine gas, direct sunlight, high temperatures or a high degree of humidity. The capacitance or resistance value of the SMDs may be affected by this. - Rough handling of circuit boards containing SMDs may cause damage to the components as well as the circuit boards. Circuit boards containing SMDs should never be bent or flexed. Different circuit board materials expand and contract at different rates when heated or cooled and the components and/or solder connections may be damaged due to the stress. Never rub or scrape chip components as this may cause the value of the component to change. Similarly, do not slide the circuit board across any surface. 1.2 Removal of SMDs - Heat the solder (for 2-3 seconds) at each terminal of the chip. By means of litz wire and a slight horizontal force, small components can be removed with the soldering iron. They can also be removed with a solder sucker (see Fig. 1A) - While holding the SMD with a pair of tweezers, take it off gently using the soldering iron's heat applied to each terminal (see Fig. 1 B). - Remove the excess solder on the solder lands by means of litz wire or a solder sucker (see Fig. 1C). 1.3 Caution on removal - When handling the soldering.iron. use suitable pressure and be careful. - When removing the chip, do not use undue force with the pair of tweezers. - The soldering iron to be used (approx. 30 W) should preferably be equipped with a thermal control (soldering temperature: 225 to 250 C). - The chip, once removed, must never be reused. o 1.4 Attachment of SMDs - Locate the SMD on the solder lands by means of tweezers and solder the component on one side. Ensure that the component is Positioned correctly on the solder lands (see Fig.2A). - Next complete the soldering of the terminals of the component (see Fig. 2B). - When soldering the SMD terminals, do not touch them directly with the soldering iron. The soldering should be done as quickly as possible, care must be taken to avoid damage to the terminals of the SMDs themselves. - Keep the SMD's body in contact with the printed board when soldering. - The soldering iron to be used (approx. 30 W ) should preferably be equipped with a thermal control (soldering temperature: 225 to 250 C). - Soldering should not be done outside the solder land. - Soldering flux (of rosin) may be used, but should not be acidic. - After soldering, let the SMD cool down gradually at room temperature. - The quantity of solder must be proportional to the size of the solder land. If the quantity is too great, the SMD might crack or the solder lands might be torn loose from the printed board (see Fig. 3). 2.

CA110 1. SUMMARY The LCD Colour Analyzer CA-110 was designed to upgrade the white-balanceprocess on production lines for colour LCD televisions and computer colour LCD panels in the colour LCD industry. The CA-110 consists of a main unit and a measuring probe. The measuring probe utilizes an optical system suitable for measurement of colour LCDs and is equipped with a viewfinder to verify the area to be measured. 2. APPLICATIONS * White-balance adjustment and inspection on LCD production lines. * Quality control and shipping inspection by LCD manufacturers. * Inspection of LCDs upon receipt by computer manufacturers. � Go to cover page �Back Forward� 21 140S LCD Colour adjustment � Go to cover page �Back Forward� 22 140S LCD Colour Adjustment ZERO CALIBRATION Zero calibration is performed to determine the output of the measuring probe when no light reaches the sensor and to set this as the zero point to which all other measurements are referenced. Zero calibration must be performed after the POWER switch has been set ON brfore taking any measurements. To perform zero calibration : * Before performing zero calibration, check that the measuring probe has been connected to probe connector P1. 1. Check that the POWER switch is set to ON. 2. Set the measuring/viewing selector to the (viewing) position. (An image can be seen in the viewfinder, but no light will reach the sensor.) 3. Press 0-CAL. * If zero calibration is being performed immediately after the POWER switch has been set to ON, press 0-CAL after "PUSH 0-CAL KEY" appears in the liquid crystal display. 4.

The 25mm measurement area can be used for measuring LCDs with 2 - inch or greater diagonals: the 50mm measurement area can be used for measuring LCDs with 4 - inch or greater diagonals. o I o I o I o I Set the measurement area : Using a slotted screwdriver, loosen the lens - barrel locking screw. Slide the lens barrel to the position corresponding to the desired measurement area. The lens barrel should be slid in the desired direction until it stops. Extending the lens barrel fully sets the 25mm measurement area: retracting the lens barrel fully sets the 50mm measurement area. Use the screwdriver to tighten the lens - barrel locking screw and lock the lens barrel in position. Changing the measurement area also changes the measurement angle. this may result in differences between values measured with the 25mm measurement area and those measured with the 50mm measurement area to the viewing - angle characteristics of the LCD. For this reason. it is recommended that the measement area be constant for all measements. o I o I o I o I 2.

Be sure to check over the entire set, not just the areas where you have worked. Some previous servicer may have left an unsafe condition,which could be unknowingly passed on to your customer. Be sure to check all of the following: 1. Be sure all components are positioned in such a way as to avoid the possibility of adjacent component shorts. This is especially important on those chassis which are transported to and feom the service shop. 2. Never release a repaired unit unless all protective devices such as insulators, barries, covers, strain reliefs, and other hardware have been installed in accordance with the original design. 3. Soldering and wiring must be inspected to locate possible cold solder joints,solder splashes,sharp solder points, frayed leads, pinched leads, or damaged insulation ( including the ac cord).Be certain to remove loose solder balls and all other loose foreign particles. 4. Check across-the-line components and other components for physical evidence of damage or deteriortion and replace if necessary. Follow original layout,lead length, and dress. 5. No lead or component should touch a receiving tube or a resistor rated at 1 watt or more. Lead tension around protruding metal surfaces or edges must be avoided. 6. Critical components having special safety characteristics are identified with ans bythe Ref. No. in the parts list and enclosed within a broken line * (where seceral criticalcomponents are grouped in one area) along with the safety symbols on the schematic diagrams and/or exploded views. 7. When servicing any unit, always use a seoparate isolation transformer for the chassis Failure to use a separate isolation transformer may exopose you to possible shock hazard, and may cause damage to servicing instruments. 8. Many electronic products use a polarized ac line cord (one wide pin on the plug.) Defeating this safety feature may create a potential hazard to the service and the user. Extension cords which do not incorporate the polarizing feature should never be used. 9. After reassembly of the unit, always perform an leakage test or resistance test from the line cord to all exposed metal parts of the cabinet. Also check all metal control shafts(with knobs removed), antenna terminals, handles, screws, etc. to be sure the unit may be safety operted without danger of electrical shock. * Broken line 1. All picture tubes used in current model receivers are equipped with an intergral implosion system. Care should always be used, and safety glassesworn,whenever handling any picture tube. Avoid scratching or other rwise damaging the picture tube during installation. 2. Use only replacement tubes specified by the manufacturer. 1. Be sure procedures and instructions to all your service personnel cover the subject of X-radiation. Potential sources of X-rays in TV receivers are the picture tube and the high voltage circuits. The basic precaution which must be exercised is to keep the high voltage at the factory recommended level. 2. To avoid possible exposure to X-radiation and electrical shock, only the manufacturer's specified anode connectors must be used. 3. It is essential that the service technician has an accurate HV meter available at all times. The calibration of this meter should be checked periodically against a reference standard. 4. When the HV circuitry isoperating properly there is no possibility of an x- radiation problem. High voltage should always be kept at the anufacture,s rated value-no higher - for optimum performance. Every time a color set is serviced, the brightness should be run up and down while monitoring the HV with a meter to be certain that the HV is requlated correctlv and does not exceed the specified value. We suggest that you and your technicians review test procedures so that HV requation are always checked as a standard servicing procedure, and the reason for this prudent routine is cleary understood by everyone. It is important to use an accurate and reliable HV meter. It is recommended that the HV recorded on each customer's invoice, which will demonstrate a proper concern for the customer's safety. 5. When troubleshooting and making test measurements in a receiver with a problem of excessive high voltage, reduce the line voltage by means of a Variac to bring the HV into acceptable limits while troubleshooting. Do not operate the chassis longer than necessary to locate the cause of the excessive HV. : : WSRNING OFF SERVICE NOTE Before removing the CRT anode cap, turn the unit and short the HIGH VOLTAGE to the CRT DAG ground. The CRT DAG is not at chassis ground. TELEVISION/MONITOR SAFETY GUIDELINES FOR THE PROFESSIONAL SERVICE TECHNICIAN 6. New picture tubes are specifically designed to withstand higher operathng voltages without creating undesirable X-radiation. It is strongly recommended that any shop test fixture which is to be used with the new higher voltage chassis be equipped with one of the new type tubes designed for this service.Addition of a permanently connected HV meter to the shop test fixture is advisable. The CRT types used in these new sets should never be replaced with any other types,as this may result in excessive X-radiation. 7. It is essential to use the specified picture tube to avoid a possible X-diation problem. 8. Most TV receivers contain some type of emergency "Hold Down" circuit to pervent HV from rising to excessive levels in the presence of a failure mode. These various circuits should be understood by all technicians servicing them, especially since many hold down circuits are inoperative as long as the receiver performs normally. 1. Unplug the ac line cord and connect a jumper between the two prongs of the plug. 2. Turn on the power switch. 3. Measure the resistance value between the jumpered ac plug and all exposed cabinet parts of the receiver, such as screw heads, antennas, and control shafts.When the exposed metallic part has a return path to the chassis, the reading should be between 1 megohm and 5.2 megohms. When the exposed metal does not have a return path to thr chassis, the reading must be infinity.Remove the jumper from the ac line cord. 1. Do not use an isolation transformer for this test. Plug the completely reassembled receiver directly into the ac outlet. 2. Connect a 1.5k, 10w resistor paralleled by a 0.15uf. capacitor between each exposed metallic cabinet part and a good earth ground such as a water pipe, as shown above. 3. Use an ac voltmeter with at least 5000 ohmsy volt sensitivity to measure the potential across the resistor. 4. The potential at any point should not exceed 0.75 volts. A leakage current tester may be used to make this test; leakage current must not exceed 0.5 milliamps. If a measutement is outside of the specified limits, there is a possibility of shock hazard. The receiver should be repaired and rechecked before retutning it to the customer. 5. Repeat the above procedure with the ac plug reversed.( Note: An ac adapter is necessary when a polarized plug is used. Do not defeat the polarizing feature of the plug.) The primary source of X-radiation in this television receiver is the picture tube.The picturetube utilized in this chassis 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,or a Philips approved tupe. Many electrical and mechanical parts in Philips television sets have special safety related charcteristics. These characteristics are often not evident from visual inspection nor can the protection afforded by them necessarily be obtained by using replacement components rated for higher voltage, wattage, etc. The use of a substitute part which does not have the same safety characteristics as the Philips recommended replacement part shown in this service manual may create shock, fire, or other hazards Leakage Current Cold Check Leakage Current Hot Check Picture Tube Replacement Parts Replacement 1500 ohm, 10W 0.15 uF WATER PIPE EARTH GROUND TO INSTRUMENTS EXPOSED METAL PARTS � Go to cover page
