Just got my XBR55X900E w/ HT-CT290 Sound bar and it seeem to get out of sync after watching a while. I worked for about a week but now it's happening. Connected with HDMI to the correct HDMI. I've tried all the settinga dn TV and Sound bar are up to date. Any fixes or do i need to contact sony?
One odd thing is that if i switch the channel on the cable box it seems to reset for a few minutes. Then it goes out of Sync again. Onyl thing i haven't tried is to unplug the unit and reset it that way.
Welcome and thank you for considering the SONY Community!
Our apologies for the delayed response. Below are the steps we can follow to isolate the issue.
There are a number of circumstances that can cause theaudioandvideoto beoutofsync:
If watching a TV program, it could be the broadcast itself or a bad connection between your cable/satellite set-top box (if applicable).
If a DVD or Blu-ray Disc® player is connected, a poor connection or the disc itself could be the cause.
When connected to a home theater system with a digital optical cable, then there may be anaudiodelay that requires a manual adjustment on the home theater system. There may even be a setting on the TV itself causing this issue.
NOTE:Because each of the steps below represents a possible solution to this issue, check if the issue is resolved after completing each step.
Make sure that the TV has the latest system software (firmware) installed.
