But there was still a problem which, if I had even hung up my TV, not just to solve so. My TV: Panasonic TX-p42gw30 has, like most Panasonic plasma, a relatively large current connector which is not far from the holes for the wall bracket.
I had a carpenter who has hung me on the TV. The right wing has then covered exactly the connector. The carpenter was then cut with a Flex the corner so I could reintun the plug, but not perfect because of the prop, lock only needs to order the fully seated, but it goes well.
But I, and probably most of the others, have not even just to make a flex in the house something, so very important to check if there are any problems with the terminals.
