I just bought a used, "as new", UE55H6400 and I'm trying to check the actual running time. I found the "Panel Display Time" info in the Service Menu which showed 0Hr. I doubt that it's accurate, though. As I understand, PDT is set to zero by a factory reset. I found out that older TV models had another hidden menu displayed by pressing MUTE, 7, 3, 7, OK, which had a MRT value displaying actual running time. However, this sequence doesn't work on my TV. Are there any other options to check running time?
