8、an. LEAKAGE CURRENT CHECK Measure leakage current to a known earth ground (water pipe, conduit, etc.) by connecting a leakage current tester between the earth ground and all exposed metal parts of the appliance (input/output terminals, screwheads, metal over- lays, control shaft, etc.). Plug the AC
9、line cord of the appli- ance directly into a 120V AC 60Hz outlet and turn the AC power switch on. Any current measured must not exceed 0.5mA. ANY MEASUREMENTS NOT WITHIN THE LIMITS OUTLINED ABOVE ARE INDICATIVE OF A POTEN- TIAL SHOCK HAZARD AND MUST BE CORRECTED BEFORE RETURNING THE APPLIANCE TO THE
10、 CUS- TOMER. Device under test Test all exposed metal surfaces Also test with plug reversed (Using AC adapter plug as required) AC Leakage Test Leakage current tester Reading should not be above 0.5mA Earth ground - 4 - LASER BEAM SAFETY PRECAUTIONS CLASS 1 LASER PRODUCT DANGER INVISIBLE LASER RADIA
11、TION AVOID DIRECT EXPOSURE TO BEAM This Receiver uses a pickup that emits a laser beam. 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 1 foot away from the pickup lens when the diode is turned on. Do not look directl
12、y at the laser beam. Caution: Use of controls and adjustments, or doing procedures other than those specified herein, may result in hazardous radiation exposure. Do not look directly at the laser beam coming from the pickup or allow it to strike against your skin. Laser Beam Radiation - 5 - HANDLING
13、 LASER PICKUP The laser diode in the optical system of this receiver can be damaged by electrostatic discharge from clothes, body, etc. Proper electrostatic grounding for service personnel is required during servicing. BEFORE REPAIRING THE DVD MECHANISM a. Human Body Grounding: Many of the component
14、s used in this compact disc player, including the laser pickup, are sensitive to electrostatic dis- charge. Service personnel should be grounded with an electrostatic armband (1M ohm). Caution: Static charge on clothing does not escape through a body grounding wristband. Be careful not to contact th
15、e pickup or electrical components with your clothing. b. Workbench and Tool Grounding: A properly-grounded electroconductive plate (1 M ohm) or metal sheet should be fitted to the workbench surface. Tools and instruments (soldering irons, scopes, etc.) should be grounded to prevent AC leakage. c. Ma

17、TS LOCATION SymptomCauseRemedy No power. The power cord is disconnected. Plug the power cord into the wall outlet securely. The power is on, but the DVD player does not work. No disc is inserted. Insert a disc.(Check that the DVD or audio CD indicator in the DVD display is lit.) The TV is not set to
18、 receive DVD signal output. Select the appropiate video input mode on the TV so the picture from the DVD player appears on the TV screen. The video cable is not connected securely. Connect the video cable into jacks securely. The connected TV power is turned off. Turn on the TV P-SCAN is selected Ch
19、eck the front display. If P-SCAN segment is on, press P-SCAN key of remote control unit. The playback picture is poor. The disc is dirty. Clean the disc. No disc is inserted. Insert a disc.(Check that the DVD or CD indicator in the display is lit.) The DVD/VCR player cannot read the disc because it
20、is damaged or an incorrect type (for example, a CD-I) Check the a disc type, color system and regional code. Check for any scratches or smudge on the disc. Insert a readable disc. The disc is placed upside down. Place the disc with the playback side down. The disc is not placed within the guide. Pla
21、ce the disc on the disc tray correctly inside the guide. The disc is dirty. Clean the disc. A menu is on the TV screen. Press SETUP to turn off the manu screen The rating level is set. Cancel the rating function or change the rating level. The remote control is not pointed at the remote sensor of th
22、e unit. Point the remote control at the remote sensor of the unit. The remote control is too far from the unit. Operate the remote control within about 23 feet(7m). There is an obstacle in the path of the remote control and the DVD player. Remove the obstacle. The remotes batteries are exhausted. Re
