Does anyone happen to know whether the hours used display in the service menu reflects the number of hours on the panel itself or whether it's the hours the media box has been used? I've bought a 'new' 506xde that is displaying over 2000 hours. The thing is though that the build month is June making it practically impossible to have that number of hours on it. If it's just a case of swapping the media box it would be a lot easier than the whole lot. Any help much appreciated.
