check your owner's manual as they vary by the weight of the sets

You will need to purchase a suitable wall mount separately. (You'll need one for LARGE TVs.) On the back of your TV set you'll see there are 4 holes in the lower-central region of the rear panel. They are about 20" apart (left-right) and about 12" apart (up-down) These should match up with the bracket that comes with your wall mount. You will need M8 metric screws that are about 1.25" long. These will also be included with the wall mount. (Which will include some general directions for wall mounting.)

Here is a manual for your TV:

PANASONIC Viera TC P60U50 Owner Manual Page 7

The 3 most common sizes for the bolts to mount the wall mount to the TV is either M8x20mm or M6x20mm or M4x20 depends on the size of the screen. This site has a chart that will show you what to look for, for your TV M6x20mm TV to Wall Mount Bracket Phillips Bolts Screws Stainless VESA 200

Call Panasonic customer service and they will provide either the parts or the size and thread type----most of these bolts are common and can be purchased at Home depot etc.

There is an internal fault, you will need to have the set diagnoses. There are a number of boards that can cause your problem.

The picture is zooming in to much,u getting a close up large picture.Look in ur tv remote look for a button said like LCD MODE,VIEWMODE or P.SIZE,push one of those buttons on the remote to pick a picture differece view modes.That can fit ur tv screen.

Thank you for the feedback.

The screw holes are metric. The set is supplied with M5x25 screws to attach the pedestal, so the wall mount screws will be in that same range.
