100 Corporate Drive Mahwah, NJ 07430 Service Bulletin No. : OST-803 Date: May 8, 2007 _____________________________________________________________ Model: DVD-9000 Subject: 1) Countermeasure for sound interruption during the playback of a particular disc. 2) Countermeasure for the Chroma Delay at the Progressive Output. Symptom: 1) Sound interruption: Upon playing back Queen's "The Game" (DVD Audio), if the playback continued up to Track #4 after selecting Stereo in the MENU, the sound interruption occurs in approximately 12 minutes and 20 seconds. 2) Chroma Delay: On the Progressive Output image, the C (color difference) signal has delayed against the Y (intensity) signal and the color is blurred. Solution: 1) Sound interruption: The ESS MICON program file has been improved. 2) Chroma Delay: Changed the circuit and the software so that blurred color does not occur. Modification: 1) Hardware (Circuit): Replace the LP Filters with ones whose group delay time has been improved, and replace the transistors with ones whose high frequency characteristics is sufficient.
