I've got mixed up with the 10,000 on status 5 sorry, thought that seemed alot of hours watching!I managed to get to the menu using remote app on my phone whilst the TV was still going mad flicking between mute and volume.
I will contact Costco tomorrow and see what they say. Thanks very much.I believe that means 1,004 hours, and I think the 548 relates to power cycles. How many times it's been put in and out of standby. So you appear to have had the big cycle at the appropriate time, just for whatever reason you have unfortunately encountered this fault you describe. Panny or the retailer should resolve to your satisfaction.
