Most TV mount problems announce themselves before they become failures. A screen leans, an arm droops, a cable pulls tight, or the wall plate starts to move. The useful response is to identify where the problem begins instead of tightening every visible fastener.
The TV is not level
Check whether the wall plate is level, the television rails sit at equal height, and the mount has a documented post-install leveling adjustment. A wall or ceiling line can be visibly out of level, so measure from the mount and screen, not from nearby trim.
The arm sags when extended
Confirm the actual TV weight and the mount's capacity. Some arms have a manufacturer-approved tension adjustment. If the joint is worn, cracked, or outside its adjustment range, replace the mount. Extending an arm increases leverage on the wall, so also inspect the wall plate.
The wall plate moves
Stop using the mount's motion. A moving plate can indicate missed framing, damaged anchors, crushed drywall, or loose structural fasteners. Peerless-AV recommends evaluating the wall for the combined display and mount load.[1] Support and remove the screen if the attachment cannot be verified.
The television does not fit the brackets
Compare the TV's VESA pattern with the mount's documented range.[2] Check screw diameter, depth, spacers, and rear-panel shape in the television manual. Do not force rails across vents or connections.
Cables bind or show below the screen
Route signal and power separately where required, leave a controlled service loop for motion, and keep connectors from carrying cable weight. Do not put ordinary extension cords or power strips inside the wall; NFPA says relocatable power taps should not replace permanent wiring or pass through walls and ceilings.[3]
The TV feels unsafe
Keep people away and remove the load safely. CPSC documents serious injuries from unstable televisions and furniture.[4] A repair is complete only when the TV, mount, hardware, and structure are all known and compatible.
