WARNING AND LASER SAFETY INSTRUCTIONS GB WARNING NL 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 set via a wrist wrap with resistance. Keep components and tools also at this potential. F WAARSCHUWING Alle IC’s en vele andere halfgeleiders zijn gevoelig voor elektrostatische ontladingen (ESD).
LASER BEAM SAFETY PRECAUTIONS This DVD player uses a pickup that emits a laser beam. Do not look directly at the laser beam coming from the pickup or allow it to strike against your skin. The laser beam is emitted from the location shown in the figure. When checking the laser diode, be sure to keep your eyes at least 30cm away from the pickup lens when the diode is turned on. Do not look directly at the laser beam.
IMPORTANT SAFETY PRECAUTIONS Product Safety Notice J. Be careful that foreign objects (screws, solder droplets, etc.) do not remain inside the set. Some electrical and mechanical parts have special safety-related characteristics which are often not evident from visual inspection, nor can the protection they give necessarily be obtained by replacing them with components rated for higher voltage, wattage, etc.
Safety Check after Servicing Examine the area surrounding the repaired location for damage or deterioration. Observe that screws, parts, and wires have been returned to their original positions. Afterwards, do the following tests and confirm the specified values to verify compliance with safety standards. Chassis or Secondary Conductor Primary Circuit Terminals d' d 1.
STANDARD NOTES FOR SERVICING Circuit Board Indications Pb (Lead) Free Solder 1. The output pin of the 3 pin Regulator ICs is indicated as shown. When soldering, be sure to use the Pb free solder. Top View Out How to Remove / Install Flat Pack-IC Bottom View In 1. Removal Input With Hot-Air Flat Pack-IC Desoldering Machine:. (1) Prepare the hot-air flat pack-IC desoldering machine, then apply hot air to the Flat Pack-IC (about 5 to 6 seconds). (Fig. S-1-1) 2.
With Soldering Iron: (1) Using desoldering braid, remove the solder from all pins of the flat pack-IC. When you use solder flux which is applied to all pins of the flat pack-IC, you can remove it easily. (Fig. S-1-3) 3. The flat pack-IC on the CBA is affixed with glue, so be careful not to break or damage the foil of each pin or the solder lands under the IC when removing it. Hot-air Flat Pack-IC Desoldering Machine Flat Pack-IC Desoldering Braid CBA Masking Tape Flat Pack-IC Soldering Iron Fig.
2. Installation (4) Bottom of the flat pack-IC is fixed with glue to the CBA; when removing entire flat pack-IC, first apply soldering iron to center of the flat pack-IC and heat up. Then remove (glue will be melted). (Fig. S-1-6) (1) Using desoldering braid, remove the solder from the foil of each pin of the flat pack-IC on the CBA so you can install a replacement flat pack-IC more easily. (5) Release the flat pack-IC from the CBA using tweezers. (Fig.
Instructions for Handling Semi-conductors Electrostatic breakdown of the semi-conductors may occur due to a potential difference caused by electrostatic charge during unpacking or repair work. 1. Ground for Human Body Be sure to wear a grounding band (1MΩ) that is properly grounded to remove any static electricity that may be charged on the body. 2.
