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 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 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 RADIATION 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 directly 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 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 components 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 the 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. Make two standard ESD solder bridges on the Laser optic PC Board Before disassembly of mechanism or disconnect any cables in it, make two standard ESD solder bridges on the laser optic PC Board. Ground conductive wristband? for body INCORRECT CORRECT - 6 - DISASSEMBLY - DISASSEMBLY - 7 - PRINCIPAL PARTS 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 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 Check 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 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. Place 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 the 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. Replace the batteries with new ones. Other function is selected. Press the function key what you want to operate. DVD/VCR The disc is not writable DVD DISC. Remove the disc and insert a proper writable DVD DISC. The disc is CD-R/RW. Only DVD+R/+RW/-R/-RW DISC can be recorded. Remove the disc and insert a proper writable DVD DISC. The disc is full. Remove the disc and insert a proper writable DVD DISC. The disc is dirty. Clean the disc and insert a blank writable DVD DISC. The disc is a suitable DISC to record. Use the recommended DISC for better operations. The disc is finalized. Unfinalize the DISC and then record in the DISC. No picture. The DVD/VCR player does not start play back. The remote control does not work properly. Recording does not work properly. - 8 - TROUBLESHOOTING SymptomCauseRemedy The disc is not writable DVD DISC. Remove the disc and insert a proper writable DVD DISC. The disc is CD-R/RW. Only DVD+R/+RW/-R/-RW DISC can be recorded. Remove the disc and insert a proper writable DVD DISC. The disc is full. Remove the disc and insert a proper writable DVD DISC. The disc is dirty. Clean the disc and insert a blank writable DVD DISC. The disc is a suitable DISC to record. Use the recommended DISC for better operations. The disc is finalized. Unfinalize the DISC and then record in the DISC. The DVD/VCR does not respond when thebuttons are pressed. Static electricity caused by dry air. Disconnect the power plug from the outlet, and insert again. No sound is output when a function is selected. Improper connections. Make sure the component is connected correctly. Improper connections. Make sure the component is connected correctly. The input source is not properly selected Press the correct function button. Broadcast stations cannot be selected automatically. The siginals are weak.Connect an outdoor antenna. The display is dark. The sleep timer is on. Press SLEEP again No image is output when a function is selected. Recording does not work properly. - 9 - - 10 - TEST Mode shows the infomation as follows. I. Back End Version (It is to express each Buyer, each model, and version number.) II. Front End Version (It is to display the Mecha Fimware version number.) III. Back End Build time (It can be used to seperate each B/E firmware version by the day.) IV. Region No.(It is only to display region code.) operation To enter the first state of test mode, first insert a any DVD DISC and load the DISC. Then press STOP key and the front panel displays STOP. then, press key on the remote unit as follows. CLEAR - 2 - 5 - 8 -0 - CLEAR If you press key correctly, you will see the message below. Loader FW ver:X.CA05- (I : F/E version) Client ver: 0912PT-MODEL NO.- (II : B/E version) Current Region: - (III : Region Number) The update is done with CD-R. (When the firmware is changed, the updated firmware will be provided by Anam on CD-R) Put the DISC in TRAY and load the CD-R disc, and Dialogue message to confirm B/E firmware update will be diplayed on the TV screen. Updating will begin. Youll see the update progress 50% on the TV screen. When the TV screens display goes off, turn the POWER OFF. Turn the POWER ON and then DO EEPROM CLEAR. The update is done with CD-R. (When the firmware is changed, the updated firmware will be provided by Anam on CD-R) - Put the disc on TRAY at normal operation mode. - Load the DISC and Dialogue message to confirm F/E firmware update will be diplayed on the TV screen . - After about several seconds, DVD door will be open. - Turn the power off. - Turn the power on and open DISC - Remove the disc. Note: F/E update method has another method. It is that you can update using computer connections.
