DVM-2815 4 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.
DVM-2815 5 IMPORTANT SAFETY PRECAUTIONS Product Safety Notice I. Also check areas surrounding repaired locations. 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.
DVM-2815 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' 1.
DVM-2815 STANDARD NOTES FOR SERVICING Circuit Board Indications How to Remove / Install Flat Pack-IC 1. The output pin of the 3 pin Regulator ICs is indicated as shown. 1. Removal Top View Out 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) Bottom View In Input 2. For other ICs, pin 1 and every fifth pin are indicated as shown. 5 Pin 1 Fig.
DVM-2815 (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) 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.
DVM-2815 Instructions for Handling Semi-conductors 2. Installation (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. Electrostatic breakdown of the semi-conductors may occur due to a potential difference caused by electrostatic charge during unpacking or repair work. (2) The “I” mark on the flat pack-IC indicates pin 1. (See Fig. S-1-7.
