As the title said, how do I check hours of operation for a Panasonic P54Z1?


I tried a couple codes I found online for other 12G models, but nothing works so far.


I tried:

1) hold [VOL -] on TV and press [Info] on remote for 3 times

2) hold [VOL -] on TV and press [0] on remote for 3 times


Thanks!

I figured it out!


For the P54Z1, I have to press and hold the [VOL -] button on the tuner box, not the TV.
