The Panasonic Viera TH-42PZ8U has a big 42-inch screen and therefore seems scarier to hang it on the wall than a smaller TV because the bigger the TV, the harder the crash. The good news is that if you mount it correctly, there is no reason for the TV to fall from the wall. The Panasonic Viera TH-42PZ8U is made with VESA holes in the back that are specifically designed for mounting your TV. In other words, the Panasonic Viera TH-42PZ8U was made to be mounted.
Use a wall stud finder to find two vertical wall studs where you want to mount your TV. Once you have located the studs, draw an outline of the wall studs on the drywall so you know where the studs are for future reference.
Hold the wall plate against the wall where you want to mount it. Make sure the mounting holes of the wall plate are lined up over the wall studs. Insert the lag bolts through the mounting holes of the wall plate and screw them into the wall stud using a Philips screwdriver. The wall plate is now mounted on the wall.
Position the TV so you can easily access the back. Locate the VESA holes on the back of the TV. The VESA holes are aligned in a box-shaped pattern. Place the mounting bracket against the back of the TV so the VESA holes line up. Insert the VESA screws through the mounting bracket's VESA holes and tighten with a Philips screwdriver.
Lift the TV with the screen against your chest and take it to the wall plate. Have a friend guide the brackets connected to the back of the TV into the connectors of the wall plate. Insert the security screws through the brackets and into the connectors and tighten with a wrench.
