Safety regulations require that the unit should be returned in its original condition and that components identical to the original components are used. The safety components are indicated by the symbol . 2. In order to prevent damage to ICs and transistors, all high-voltage flash-overs must be avoided. In order to prevent damage to the picture tube, the method shown in Fig. 1 should be used to discharge the picture tube. Use a high-voltage probe and a multimeter (position DC-V). Discharge until the meter reading is 0 V (after approximately 30 seconds). 3. ESD All ICs and many other semiconductors are sensitive to electrostatic discharges (ESD). Careless handling during repair can drastically shorten their life. Make sure that during repair you are connected by a pulse band with resistance to the same potential as the ground of the unit. Keep components and tools also at this same potential. 4. When repairing a unit, always connect it to the AC Power voltage via an isolating transformer. 5. Be careful when taking measurements in the high-voltage section and on the picture tube panel. 6. It is recommended that saferty goggles be worn when replacing the picture tube. 7. When making adjustments,use plastic rather than metal tools. This will prevent any short-circuit or the danger of a circuit becoming unstable. 8. Never replace modules or other components while the unit is switched on. 9. Together with the defleciton unit, the picture tube is used as an integrated unit. Adjustment of this unit during repair is not recommended. 10. After repair, the wiring should be fastened in place with the cable clamps. 11. All units that are returned for service or repair must pass the original manufactures safety tests. Notes 1. The direct voltages and waveforms are average voltages. They have been measured using the Service test software and under the following conditions : - Mode : 1024 * 768 (56.5kHz / 70Hz) - Signal pattern : grey scale - Adjust brightness and contrast control for the mechanical mid-position (click position) 2. The picture tube panel has printed spark gaps. Each spark gap is connected between an electrode of the picture tube and the Aquadag coating. 3. The semiconductors indicated in the circuit diagram(s) and in the parts lists are completely interchangeable per position with the semiconductors in the unit, irrespective of the type indication on these semiconductors. � Go to cover page Forward Back Mechanical Instructions 8 109B2 GS3 CM25 Fig. 5 Fig. 4 Fig. 3 Fig. 6 Fig. 8 Fig. 2 Fig. 7 screw 0.

Purity adjustment 2. Static convergence - Make sure the monitor is not exposed to any external magnetic field. - Produce a full red pattern on the screen, adjust the purity magnet rings on the PCM assy (on CRT) to obtain a complete field of the color red. This is done by moving the two tabs (2-pole) in such a manner that they advance in an opposite direction but at the same time to obtain the same angle between the two tabs, which should be approximately 180 degree. - Check by full green pattern and full blue pattern again to observe their respective color purity. Introduction Slight deviation in the static convergence can be corrected by using two permanent pairs of magnets which are fitted around the neck of the CRT. These are the 4-pole magnet and the 6-pole magnet. The 4-pole magnet move the outermost electron beams (R and B) parallel in the opposite direction from the other. The 6-pole magnet moves the outermost electron beam (R, B and G) parallel in the opposite direction from the other. The magnetic field of the above magnets do not affect the center of the CRT neck. Setting - Before the static convergence setting can be made, the monitor must be switched on for 30 minutes. - The focus setting must be made correctly. - Signal: 640 * 480, 31.5 kHz/60 Hz mode. - Set the tabs of the 4-pole magnet in the neutral position. This is when the tabs are opposite one another. In this position the magnets do not affect the deflection of the R and B electron beams. - Set the tabs of the 6-pole magnet in the neutral position. This is when the tabs are opposite one another. In this position the magnets do not affect the deflection of the R, B, and G electron beams. - First set the 4-pole magnet optimally. - Then set the 6-pole magnet optimally. - If the convergence is not now optimal, then adjust to the optimal setting with the 4-pole magnet and then with the 6- Pole magnet again. - Set the tabs of the 6-pole magnet in the neutral position. This is when the tabs are opposite one another. In this position the magnets do not affect the deflection of the R, B, and G electron beams. - First set the 4-pole magnet optimally. - Then set the 6-pole magnet optimally. - If the convergence is not now optimal, then adjust to the optimal setting with the 4-pole magnet and then with the 6- pole magnet again. 2-pole purity magnet 6-pole convergence magnet 4-pole convergence magnet Deflection

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.

This highlighting is done by boosting the brightness and sharpness on a selected region of the monitor screen. Since high brightness and sharpness are not preferred for most standard Windows applications, this special feature will only be active in certain circumstances. So that you can control these circumstances, a special program and icons will be installed in your Windows operating systems. Philips LightFrame will only work with monitors that have been built to use this software. Earlier Philips monitors or other manufacturers’ monitors will not work with this special software. It is recommended that you install this software only on a Philips monitor designed to use it. These monitors can be identified by the LightFrame™ logo on the front of the monitor. This software is not designed for use with LCD flat screen monitors. LightFrame will work with true Windows-based programs and DOS- based programs that operate in a Window’s environment. It will not work with DOS-based programs operating only in a DOS environment. The following list contains definitions for frequently used words. Highlighted window: The selected window on which LightFrame is active. Highlighted area: The selected rectangle (area) on which LightFrame™ is active. This version of LightFrame™ is compatible with Windows 95 Windows 98 Windows NT Windows 2000 Professional Edition. While English is the default language of LightFrame™, the User Interface can be set up to operate in Dutch, French, German, Italian, Portuguese, or Spanish. 1) To install LightFrame™, place the CD in the CD-ROM drive. 2) Next, when the menu of items on the CD appears on your screen, click on 'Install LightFrame '. 3) Now, follow the on-screen prompts to properly install the program. The software checks to see if you have a compatible monitor. You must say yes to the license agreement for the software to install. 4) After installation, LightFrame automatically loads and the icon appears in the taskbar. LightFrame is installed in the Start menu, under Programs. Unless otherwise selected during installation, LightFrame is installed in “C:\Program Files\Philips\LightFrame.” A shortcut is installed in the StartUp folder and on the desktop. (If needed, LightFrame can be operated manually from the StartUp folder.) If LightFrame detects that your monitor is not LightFrame compatible, an message appears on the monitor screen. See Error Message number 1 under the heading Error Messages. If you see this message, you can select to abort or continue the installation. However, if you continue the installation, LightFrame will probably not work on the monitor. ™ ™ ™ ™ ™ ™ ™ ™ ™ ™ ™ ™ Notes Notes Uninstall Operating LightFrame Icon and Colors How To Activate LightFrame How to Deactivate LightFrame Should you need to remove the LightFrame software, please follow these steps. 1) First, click on the Start Menu. 2) Next, highlight Settings. 3) Then, click on Control Panel. 4) Now, click on Add/Remove Programs 5) Finally, select LightFrame from the list and then click on the Add/Remove button. After installation, LightFrame starts up automatically whenever the computer is started. At system start up, LightFrame checks the selected resolution of the monitor and if the monitor is LightFrame capable. An icon of a monitor represents LightFrame on your desktop. This icon appears as a shortcut on the Windows desktop. LightFrame has three (3) modes of operation: Active, Inactive, and Suspended. The same icon with a different color in its center represents each mode. Active = The LightFrame icon has bright green center. Inactive = The icon has a gray center. Suspended = The icon has a yellow center with a red cross. An active window must be 100% visible, i.e. it must be on top of all other windows or areas. If any part of another window or area overlaps a highlighted window, LightFrame automatically suspends operation. That means the icon goes from a green center to a yellow on with a red cross and the feature ceases. Once that window or area is removed and the original highlighted window is on top again, LightFrame automatically re-engages and the icon regains its bright green center. An active window must also be 100% on the monitor’s viewing area. If part of a highlighted window moves off the monitor’s viewing area, LightFrame automatically goes into the Suspended mode. If part of a window is off the viewing area, you will not be able to use LightFrame on that window. Only one window or area at a time can be highlighted. 1) Click on the LightFrame icon in the systemtray (the area to the far right in the taskbar). . The icon will turn from gray to a green center. 2) Guide the mouse to the window you want displayed. As you move the mouse, the cursor changes to a small arrow with a light bulb. 3a) Click on the window you want to have highlighted. The brightness and sharpness are automatically adjusted. 3b) If you want to highlight only an area of a window, click on the left mouse button and drag the cursor over the area to be highlighted while holding the mouse button. A rectangle forms around the area. When the area is encompassed by the rectangle, release the mouse button and the area becomes highlighted. To deactivate, click on the LightFrame icon in the System Tray of the Taskbar. The light in the middle of the icon turns gray and LightFrame is deactivated. If a highlighted window is closed before LightFrame is deactivated, LightFrame is automatically deactivated. ™ ™ ™ ™ ™ ™ ™ ™ ™ ™ ™ ™ ™ ™ ™ ™ ™ ™ ™ Notes Note 72 109B2 GS3 CM25 Go to cover page Forward Back LightFrame for Windows (Continued) ™ Right-Click Features LightFrame is Suspended When . . . Error Messages On the LightFrame icon in the taskbar, click the right-side mouse button to bring up a menu from which you can select: which tells you something about LightFrame which takes you to the Help screen where you can find additional information which exits the LightFrame Program. If you select exit and the color in the center of the icon is green, it will turn gray and LightFrame is deactivated. If you select exit an Exit message appears asking you if are sure you want to exit. Select "Yes" to exit or “No” to abort the exit. If you select Yes, you can always restart LightFrame by clicking on the desktop shortcut icon. LightFrame goes into the Suspended mode as soon as a screensaver becomes active on your computer. This is true even though the monitor icon may still have a green center. LightFrame becomes active again as soon as the screen is reawakened and the screensaver quits. The same is true when the computer goes into Sleep mode or Deep Sleep (Power Off) mode. LightFrame goes into Suspended mode and reawakens when the monitor is reawakened. LightFrame suspends when a highlighted window is minimized. LightFrame reactivates when the highlighted window is again maximized or restored to its previous size. LightFrame suspends if a window that is not highlighted overlaps a highlighted window. LightFrame reactivates once the highlighted window is again on top. If the monitor is “hard powered off” while a window or area is highlighted and then hard powered on again, LightFrame is no longer active. The icon may still show the feature as still active. In this case, you have to exit LightFrame and restart it via the icon on the desktop or the Start menu.

Go to cover page Safety Checks Fire and Shock H azard Implosion X-radiation After the original swevice problem has been corrected,a complete safety check should be made. 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
