I have a question regarding audio sync issues with the 42LG30 LCD TV. I recently switched my cable box from component to HDMI. After switching to HDMI, I noticed that there were some audio sync issues. I notified LG, and they shipped me a usb drive with an update that is supposed to fix the issue. I have plugged the usb drive into the TV and nothing happens. Apparently a menu is supposed to pop up with my TV model number. After selecting the model number, further directions are supposed to pop up. It says if the menu does not pop up immediately to turn TV off, and then turn it back on and insert drive. After inserting the drive it says to press menu on the remote then highlight option and press the 7 button 7 or more times to get the menu stored on the usb drive to display. No luck with any of those tactics. Has anyone else experienced this problem? Any other ideas on how to get the usb menu to display? LG customer service had no clue how to help me. They are going to send me another usb drive, but I don't have high hopes after this experience. I apologize if this has already been posted, and thanks for any help you can provide!!
