My TX-65JZ1500 is still in its box and I shall wall mount it using a Sony SU-WL850 bracket. My studded wall was custom made to fit a bracket for a non VESA TV and so I cannot rely on industry standard vertical or horizontal stud pitch. The Panasonic TV manual does not show the height from the bottom of the TV to the bottom VESA hole. It is this dimension that I am seeking. I would be grateful if anyone would confirm this dimension before I start drilling too many test holes! Our room is in the middle of renovation I would prefer to leave the TV in its box until the time to lift it into position.
