2 HOW TO LOAD SOFTWARE FOR MPEG P.W.Board Trouble shooting during loading software a. Trouble "Case 1" If under above mentioned situation "c" and "d" the tray has not opened, within 60 seconds after "READING" has been displayed on "FL", pull off the power cord and then plug it in again. Then recommence the procedure from the beginning. b. Trouble "Case 2" If under situation above mentioned "d" (after the tray has opened automatically), the STANDBY LED has not light up in red after 30 seconds, pull out the power cord and then plug it in again. Then recommence the procedure from the beginning. In the case that the LED does not light up in red even if the power cord has been re-plugged in, please follow the trouble shooting case "Trouble Case 4". c. Trouble "Case 3" If under above mentioned situation "e" (before the tray has opened automatically), when power is down, it means that updating has failed. Pull out the power cord and plug in again. Then recommence the procedure from the beginning. d. Trouble "Case 4" If under above mentioned situation "e", when any unusual performance has been found caused by a power failure or any other problems, no key operation will work even after power is switched ON. In these cases, close the tray gently with fingers while the updating disc is set on the tray. When the tray is pushed slightly, the tray will close automatically. Then follow procedure "e". When the tray was closed while updating disc has not been set under unusual performance, the tray opens automatically to request the updating disc. 2. Change of DVD P.W.BOARD and DVD MECHANISM A.
