Anand Number of Pages Available. Snapshot About the book. Do not leave the soldering iron on the transistor terminals too long.
Mark pin 1 on the PC board with a felt pen. Remove the old IC with solder-wick and soldering iron. Use longnose pliers or heatsink tool to dissipate the heat.
Leave it in the envelope until it's ready to be installed. Doublecheck the transistor wire terminals and the bottom base diagram Fig. Correct mounting of 1C is found in the solid-state replacement guide. Place silicon grease and metal heatsink behind large ICs.
Lift the defective IC out by prying underneath the component. Move the mesh down as it picks up solder. Place silicon grease between the transistor. Check for the terminal 1 dot. Flick the pin with a pocket blade or with a small screwdriver. Look in the replacement guide for a universal IC replacement if the original one is not available. Handle it with care. The horizontal drive wavefom from the oscillator stage can be traced through. When looking down on top of the IC.
Pin 1 is indicated with a white dot. Crucial waveforms taken in these circuits are functioning. To horiz. The defective motor circuits in the CD player and camcorder can be located with the oscilloscope. If one of the waveforms is missing or if there is incorrect polarity and improper waveform. A double resistor chip contains two resistance elements of a different value in.
The microprocessor can have gulltype wings or elements that solder directly on the PC board Fig. The scope waveform can locate a weak. Just compare the audio signals in both channels at a given point.
It's wise to acquire the exact part from the manufacturer for replacement. The surface-mounted components. The resistors. These ICs might have more than 80 different soldered elements. Now take voltage. If the waveform is improper or missing. You might find a part that looks like a resistor. C ' s SMDs. The digital transistor might have the base and bias resistors mounted inside of the surface-mounted component. Notice that the PNP digital transistor has the base and bias resistors tied to the emitter terminal.
When a resistance measurement is taken. These chip compunents take the place of wire jumpers to tie two different circuits together on the regular PC board. The first two numbers indicate the resistance value. Fixed capacitors and transistors might contain stamped letters and numbers on the top side of the component. Small SMD replacement capacitors. Fixed resistors can be marked with white stamped numbers. The small transistor might have all three elements out of the bottom.
In the last position. You might find round capacitors and resistors instead of flat-chip components in some TVs. Notice that a feed-through SMD part can be easily mistaken for a fixed resistor. A resistor with the numbers has a value of 12 kS1. Determine whether the transistor is a standard or a digital t y p e before testing Fig. You might ftnd more than one diode in the surface-mounted c o m p nent.
When making transistor tests on digitd transistors. A different hookup connection can be made with positive and anode connections. A h the defective IC has been located. Some have from 40 t o 80 different terminal connections found in the CD player Fig.
Slowly slide the wick along as the solder is melted. ICs are sensitive to static electricity. The surface-mounted parts can be resistors.
Do not keep the soldering iron on one area for any length of time to avoid lifing the wiring. Beat the area by laying the wick material along the row of terminals.
You might also see LEDs with a compact. A solder sucker that fits over an IC terminal can quickly remove solder from around the pins. Keep them in the foil or static containers until you are ready to instakl them. These components are mounted flat on the board. ICs handle many other functions. The digitd signal processing LSIs can integrate up to 13 or more different digital functions in a single chip. Remove the solder around the leads with a solder sucker or solder wick.
Some have more than five different kinds of ICs. Always obtain these parts h m the manufacturer because they mount perfectly. Use extreme care so as not t o damage the PC wiring.
The resistor has a number for identification with lines at the ends. If they are not obtainable. Use a W pencil or regulated soldering iron Fig.
The quickest and easiest method is with the diode test of a DMM. The surface-mounted transistor might appear in a chip form with flat contacts at one side. Throw away all surfice-mounted components removed fiom the chassis. Clean off lumps of solder from the wiring with the soldering iron and solder wick. I Many different surface-mounted devices are used in CD and cassette players. Be sure that all solder is removed before lifting small components. The resistors appear as round.
Because many surhce-mounted devices have similar shapes and sizes. These transisbrs and diodes can be tested like any regular diode or transistor. You might find more than one transistor inside one chip. Remove jagged or overlapping solder horn the PC wiring with solder mesh material. Do this to each terminal until all are removed. Two or more fixed diodes might be found in one component. Some larger components might be glued underneath. The ceramic capacitor is a flat.
Do not use a large soldering gun and solder wick to remove small surface-mounted cornponents. Transistors and diodes are o h identified with two letters. Be very careful not to short them out when you take voltage measurements on these terminab with test probes. Hold the part with a pair of tweezers and twist as the compunent is removed. To remove a surface-mounted transistor or diode.
Use small-pointed test probes when making tests on S M D components. They should not be used after removal. Grasp the end of the component or lead and melt the solder from the other end. Do not leave the soldering iron on the transistor or IC terminals for too long.
Lay the component over the end pads with a pair of tweezers. Remove only one S M D component fiom the package because you might m n h s e the values. Replace all chip components. Check the new compunent before installation. Now solder the other end.
The large IC or processor should be flat and should mount right over each correct termind mnnection. Use extreme care not to damage the new chip. Recheck the SMD aRer installation.
Tin or presolder the contact p i n t s on the circuit pattern or wiring. Inspect the soldered joint with a magnifying glass. Do not bend or apply pressure to the transistors or IC terminals in the replacement. Be careful because these tiny devices can flip out of sight. Touch up b t h ends of the flat compunent with solder. Avoid using a rubbing stroke when soldering. Apply more solder over the terminal if it is needed for a good b n d.
Use a soldering pencil or regulated soldering iron tmponents. Do not drag the TV chassis over the bench because the surhce-mounted components can be damaged.
Press down the component with tweezers and apply the soldering iron to the terminal connections Fig. Use the smallest diameter of solder available for SMD connections. Place it upon a piece of white paper so that you can see it. Tack in one end with solder to hold it in place. CD players. The double-sided board Is used In portable radlos. In many of the compact CD players with only one large PC board.
Double-sided PC boards are used in small portable radios. A hair-line crack is difficult t o see on a PC wiring connection. In some chassis. Double-sided wiring presents various service prob1ems when iroubleshooting the chassis.
FiRy years ago. Set aside one hour a day for study. Locate the manufacturer's parts layout section. You might need to make various voltage and signd tests on components m the top side that feed through to the suspected component underneath. Howard W. Cracked wiring and surface-mounted element connections can break loose if the b a r d has the opportunity to warp or sag. If test points are not provided on the top side of the chassis. Motors were brought to him from miles around. Besides attending the manufacturer's service meetings.
This hour a day can keep you abreast of new developments and provide more efficient use of your time in eleckonic servicing.
These components lay flat and solder directly to the wiring. He would go to work at 7 a. Read and Study With the electronic service business changing from year to year. Some technicians place the repairs in a 3"-X-5" file-card system. One quick method is to list the problem along the side of the schematic diagram.
Long troub1eshooting techniques can also be stapled t o the service literature. The same service problem might occur over and over again in another chassis. One case history might save hours of time in the busy world of electronic servicing. You cannot possibly remember all of the various problems related to a special TV chassis. Preventative Maintenance Repeated call backs can be eliminated if preventive maintenance procedures are followed in servicing the electronic chassis.
Each part can be identified on the schematic for easy reference. He was efficient. Case Histories The tough or unusual repairs on TV. Replace any dial light that comes on. Be sure that it fits properly and is not loose or falls off. Check for a loose dial bulb assembly or poorly soldered connections if the lamp is intermittent.
Check for poorly soldered terminals and hookup wires around highwattage resistors. Do not forget to clean the TV tuner assembly after each repair job. Sometimes the capacitor can explode. Replace the spring or the entire knob. If a small control is frozen. Most rotary tuners need to be cleaned once per year. The same applies to neon lights o r neon bulbs. Recheck the tape speed. Repair or replace burned terminal strips connected to various heated components.
Enlarged areas on the body of the capacitor might indicate the need for replacement. Check the motor drive belts for slippage and replace them. Check each h o b. Check for good soldered connections of highwattage resistors. Check the ends of small filter or bypass capacitors for signs of deformed o r cracked ends.
Always clean the tape heads. This indicates that the bulb will not last very long. Clean the capstan bearing and apply a drop of light grease on bearing area. Lubricate the tuner bearing areas. Squirt an approved cleaning fluid inside of the volume. Always check each dial light and see if it is lit. As in every job. Besides making a good living.
Although the high voltage generated in the TV chassis might be above 32 kV. The 3. Discharge filter capacitors before checking voltages in the power-supply circuits. The same can occur if the capacitor is instaIIed backwards.
Be sure that voltage test instrument cables are good. Work on a rubber mat to protect yourself not only from electrical shock. Safetv Lessons Besides having each service bench fused with grounded polariv outlets. Think before you leap when working in the ac power line or high-voltage circuits.
Safely rules followed everyday can prevent numerous injuries. Get in the habit of playing safe. Sometimes a Laky horizontal or power regulator transistor can be red hot.
It takes only one picture tube explosion to damage your eyes for life. Wear safety goggles when replacing a picture tube. Keep the chassis away fiom grounded pipes or metal bench posts. Be careful whlle wvrklng on electrvnlc products that operate from the ac power line. Be sure that the power cord is disconnected if you touch a component such as the flyback transformer.
Discharge the picture tube before attempting t o remove it. Use an isolation variable power transformer with all TVs. Remember that the safety capacitors in the horizontal output transistor circuit hold down the high voltage at the flyback and anode terminals of the picture tube. If the current reading is higher. This current measurement check should be less than 0. Keep the high-voltage lead tied up away from components on the chassis.
Make the hot current test as follows: Tie cables up by folding long wires. Now reverse the power cord in the outlet and repeat the test. If the exact capacity is not used. Always replace with exact capacity and working voltage. If the resistance measurement is less that 1. Be sure that the speaker wires or cables are not pinched between chassis and bottom side areas. Excessive HV can cause sharp cracking of arcover voltage to the chassis.
The safety capacitors in the collector circuit of the horizontal output transistor prevents the HV from increasing to a dangerously high voltage. Take the antenna cold check and leakage hot check. If components with the manufacturer's exact part number are not available. For the antenna cold check. Safety components in the low-voltage power supply include capacitors.
Replace crucial capacitors and resistors in the horizontal output circuits with the exact type of part. IC Hor. You can find oxide metal-film type resistors in voltage-divider networks.
These crucial compnents are used in the low-voltage power supply. High-voltage fixed resistors should be replaced with those that have the same RL nuwer 'Critical components Replace all safety parts in the TV chassis. Some crucial parts are identified by a black triangle symbol in some schematics A. Route wires covered with PVC tubing. Do not leave long leads on capacitors and resistors that can flop around.
The TV chassis might be called a hot chassis. Take pride when replacing those new components. PVC tubing. Replace wire-wound resistors with those that have the same or higher-wattage parts. K such as prrwer transistors.
Make clean soldered joints or bonds. Use specified insulated materials for hazardous live parts. Replace the new component in the exact space as the original. Sloppy part replacement can cause flames. Do not touch the metal body of the horizontal output transistor while the chassis is operating. Overheated horizontal output and regulator transistors might be too hot to touch. A defective component in the low-voltage circuits can operate for a while md then cause chasQ horiz out From horiz driver To flyback - T C 1 R 2!
D Check for improper drive voltage or waveforms at the horizontal output transistor ti the fuse keeps blowing. Suspect that the HV shutdown circuits are defective if the chassis shuts down before the correct HV has been reached. The primaq line fuse in the ac TV power supply might be a 1.
The horizontal circuits within the TV chassis might operate with a hot ground.
Suspect lightning damage if the fuse holder is blown apart and the PC wiring is stripped. Always replace the line fuse with w e that has the exact ratings. Most TV chassis contain a 4. Always use the "hot" ground as instrument ground when taking voltage measurements within these circuits or the voltage measurements will be inaccurate. If the glow area of the fuse is black. An improper drive voltage at the base of the horizontal output transistor can blow both fuses Fig.
The blown fuse in the TV can be caused by leaky silicon diodes. Never replace the fuse with a high rating because it could later on cause a fire. A small break in the fuse internal wire might indicate a flash-over component or power-line outage. The hot ground is used in the ac power line. If both the line fuse and secondary fuse is blown. You would now hear a cracking and arcover symptom with excessive high voltage.
If loud cracking and arc-over sounds can be heard around the HV cable. Repair the low-voltage regulator circuits. Excessive high voltage can cause the chassis to shutdown when the internal W shutdown circuits are operating. A defective HV shutdown circuit might cause the chassis to shut down at once or it might not shut down the chassis at all. If the HV shutdown circuits are functioning.
The high voltage at the picture tube should never go over the manufacturer's listed high-voltage measurement. Remove the chassis.
Two service technicians might be needed to remove and replace the very large picture tubes.
Do not carry the picture tube against your stomach. Remove the picture tube and lay it on its face on a rug or carpet so as not to scratch the screen area.
Always wear safety glasses or goggles when removing and installing a new CRT. Never return the TV to the customer without making these adjustments.
Be very careful when making HV tests and working around the picture tube. Discharge the CRT before removing the defective tube. Now check the HV at the picture tube. Place the front of the tube or cabinet face down on a rubber mat or rug. Remove one end of the reference diode or Zener diode from the circuits. Comprehensive, nice presented, perfect for beginners. For advanced professionals. Perhaps a good addition with more details. A picture book for hobbyist. No theory but 2.
For the practiciners or those who want to become one. Undemanding but nicely presented and not expensive. My favorite. The practical relevance makes this book very useful.
