Panasonic Plasma

Question? - Panasonic plasma. TC-P65ZT60 and TC-P65VT60.  I know you can check the usage hours and counts (power on) by going into the Service Mode in the SRV-TOOL area.  I also saw where you can check usage hours by going into the menu, Menu-Help-Version-Status 4. The Status 4 line is suppose to show usage hours. Is checking usage hours through the Menu a reliable way to check hours? I am looking to buy one of these TV's and don't have one yet to try this out.Thanks
