Here is what you need to do:
- Find two vertical studs, that is all you need TWO...
- Get a nice rectangular piece of poplar or oak (maybe 2by2 or 2by3 depending on the size of the TV; the idea is to make this an anchor for the TV).
- Affix this piece of board to the studs with 3 inch nails or screws around the location where you intend to hang the TV.
- (optional) Paint this board to match the wall color.
- Once secured, you can bold the mounting hardware anywhere on this piece of board.
- Secure the TV to mounting hardware.
If you have other items to mount such as BluRay, DVD player, Roku, etc. follow the steps below:
- purchasePurchase a pack of "cable tie mounts"
- packPack of thin zip tie (the idea is to place cable mount at the location where you plan to mount the device example, device is 4 by 4 inch, secure four cable mount 1 inch apart and 4 inch between in height)
- runRun zip tie under those cable ties and secure device you wish to mount.
Let me know if you need clarification on any of this.
