It is advised to insert an isolation transformer in the AC supply before servicing a hot chassis. The critical safety components marked with on the schematics diagrams should not be by other substitutes. Other substitute may create the electrical shock , fire or other hazards. Take attention to replace the spacers with the originals.
Furthermore where a short circuit has occurred , replace those components that indicate evidence of overheating. After servicing , see that all the protective devices such as insulation barriers, insulation papers, shields and isolation R-C combinations are correctly installed.
When the receiver is not being used for a long time of period of time , unplug the power cord of the Adaptor from the AC outlet. Please earth human body when handle the LCD. In addition, please do not touch the interface connector pin with bare. Please follow following guidance. Turn the power off when do not use. Change the pattern periodically. Unplug the AC cord and connect a jumper between the two prongs of the plug.
Measure the resistance value with an ohmmeter, between the jumpered AC plug and each exposed metallic cabinet part on the receiver. When the exposed metallic part a return path to the chassis the reading should be between 4Mohm and the 20Mohm.
When the exposed metal does not have a return path to the chassis, the reading must be infinite. Surface of polarizer is soft and can be physically damaged easily.
Please do not touch, push or rub polarizer surface with materials over HB hardness. Please wear rubber glove when touch the surface of LCD screen. Please use soft and anti-static material as cleaner. Please wipe out dry or water carefully. LCD is not proper to be used at high temperature and high humidity. Please keep specified temperature and humidity condition. Corrosive gas effect the polarizer and the circuit chemically and cause defects accordingly.
Plug the AC cord directly in to the AC outlet. Do not use an isolation transformer for this check. Connect a 2Kohm 10W resistor in series with an exposed metallic part on the receiver and an earth, such as a water pipe. Use an AC voltmeter with high impedance to measure the potential across the resistor. Check each exposed metallic part and check the voltage at the each point.
Bush D Remote Control. Bush 14RC Remote Control. Bush WS Remote Control. Ironically the cheaper dvd players can be made multi-region with simple remote commands sent from the remote that was supplied with the unit. Or they were already capable of playing discs from all regions straight out of the box.
However, this is not the case for the more expensive Sony, Panasonic and pioneer units. Although you can send special commands from a palm-pilot or magic remote it is a difficult procedure. We have made a remote that sends all the commands in one simple key press. Such 'chipped' remotes have been around for a good while but were usually one use only, rented and always expensive.
You can make up to 8 dvd players multi-region with these. As many people enjoy the security and benefits of ebay we sell many remotes on there too, over in fact were sold in the year
