Quick summary: If your TV starts tilting over time, the cause is usually related to the mount’s adjustments, VESA attachment, weight capacity, connections, or wall installation. First, identify what has shifted and check the hardware and cables. Then decide whether the mount needs adjustment or replacement.
After installation, a TV may stay in its intended position for a long time: the screen is level, the tilt angle is set, and the mount holds it securely on the wall. Over time, however, you may notice a change. One side of the screen may sit lower than the other, the TV may start tilting forward, or it may no longer stay in place after adjustment.
The TV itself is not always the cause. More often, you’ll need to check the mount’s adjustment mechanisms, weight capacity, VESA compatibility, wall attachment, and cable routing.
Let’s look at why a wall-mounted TV may start tilting, what you can check yourself, and when adjustment alone is no longer enough.
What Has Changed? Identify the Problem
Before making adjustments, identify exactly how the TV has shifted. This will determine what to do next.
The Screen Tilts Forward
The most common issue is that the top of the TV gradually tips forward and the screen no longer holds the selected tilt angle.
Start by checking:
- The tilt adjustment mechanism.
- Whether the TV’s weight is within the mount’s rated capacity.
- Whether the fasteners are secure.
- The condition of moving joints, especially if you reposition the TV regularly.
This misalignment is especially noticeable on large TVs: the wider the screen, the more visible even a slight shift becomes.
Some full-motion TV wall mounts allow you to level the screen after installation. For example, the ONKRON M6L-B provides ±4° of levelling adjustment to correct minor installation misalignment. However, if one side of the screen keeps dropping, leveling it again is not enough. You need to find the cause first.
One Side of the TV Is Lower Than the Other
If the screen leans noticeably to the left or right, possible causes include:
- Unevenly secured mounting components.
- VESA mounting rails that have shifted.
- Play between the TV and the mounting plate.
- Movement in an adjustable joint or an installation that was not level to begin with.
The TV Changes Position When the Mount Is Extended
With a full-motion mount, extending the TV farther from the wall increases the leverage on the structure. A mount that is in good condition and compatible with the TV’s weight and other specifications should hold the screen in the positions intended by the manufacturer.
If the TV changes angle on its own after repositioning or needs repeated adjustment, check:
- The adjustment of moving joints.
- Whether the TV’s weight is within the mount’s rated capacity.
- The condition and security of the connections.
The Mount Moves Against the Wall Along With the TV
If the wall plate moves along with the TV, the issue may be with the installation.
In this case, check:
- The mounting hardware.
- The condition of the supporting surface.
- Whether there is any play between the wall plate and the wall.
- Whether the hardware is suitable for the wall material.
If the wall plate is pulling away from the wall, cracks appear, or the fasteners visibly shift, stop using the mount until the installation has been checked.
Common Causes of a Tilting TV
A Loose or Incorrectly Adjusted Tilt Mechanism
Many TV wall mounts let you change the screen’s tilt angle. The mechanisms that hold it in position vary by model.
If you adjust the TV frequently, check the mechanism periodically as directed by the manufacturer. If the mount is in good condition and compatible with the TV, correctly adjusting the locking mechanism may be all that is needed.
Do not simply tighten the adjustment screws as far as they will go. The correct adjustment direction and amount of force depend on the mount’s design.
The TV Exceeds the Mount’s Weight Capacity
One possible cause is a mount that is not suitable for the TV.
Consider the TV’s weight as well as its screen size. Two TVs with the same screen size can have very different weights, so screen size alone is not enough.
When choosing a TV mount, check:
- Its maximum weight capacity.
- Its supported screen size range.
- VESA compatibility.
- Any other TV compatibility limits specified by the mount manufacturer.
The TV’s weight must not exceed the mount’s stated maximum capacity. If you are unsure whether your TV and mount are compatible, see “How to Choose a Wall Bracket for Your TV.”
Incorrectly Installed VESA Mounting Rails
The VESA mounting standard specifies the spacing between mounting holes on the back of a TV. If the rails are misaligned or the screws are tightened unevenly, the screen may hang crooked.
Before installation, check that:
- The TV’s VESA pattern is supported by the mount.
- The mounting rails are positioned symmetrically.
- The correct screws and spacers are being used.
- All mounting points are secured evenly.
Loose Connections
If you frequently tilt, swivel, or extend the TV, periodically inspect the connections and locking components identified in the manufacturer’s instructions.
Pay particular attention if:
- There is noticeable play.
- The screen no longer stays in position.
- The mechanism moves differently than usual.
- You hear unusual sounds or see components shifting.
Follow the instructions for your specific TV mount when inspecting or adjusting it.
Wall Installation Issues
Even a compatible TV mount cannot provide a secure installation if it is attached to an unsuitable surface or installed with the wrong hardware.
The installation method depends on the wall’s material and construction. Concrete, solid or hollow brick, structural wood, and framed walls may require different mounting methods. With drywall, it is especially important that the load is supported by an appropriate structural element, rather than the drywall sheet alone.
If you are unsure, see “How to Install a TV Wall Mount.”
Cable Tension
Cables can sometimes affect the TV’s position. This is especially noticeable with full-motion mounts when a cable is too short or becomes taut as the TV swivels or extends.
A cable can:
- Pull the TV to one side.
- Restrict the mount’s full range of motion.
- Put extra force on the TV at the limits of its travel.
Leave enough cable slack for the mount’s full range of motion, and organise excess cable using the provided cable management features.
What You Can Check Yourself
You can perform a visual inspection and compare the TV and mount specifications. If the wall plate is pulling away from the wall, or you see cracks, noticeable play, or damaged components, stop adjusting the TV until the installation has been checked.
1. Is the TV Within the Mount’s Weight Capacity?
Make sure the TV’s weight does not exceed the mount’s maximum rated capacity.
2. Does the TV’s VESA Pattern Match the Mount?
Compare the TV and mount specifications, including:
- The spacing between mounting holes.
- The supported VESA patterns.
- The screws and spacers being used.
3. Is There Any Play Between the TV and the Mounting Plate?
Inspect the connection between the TV and the mount:
- Check for any play.
- Make sure all required locking components are installed.
- Check that the VESA mounting rails are attached symmetrically.
4. Does the Tilt Mechanism Hold Its Position?
If the TV gradually tilts downward, consult the manual and check the settings of the relevant adjustment mechanism.
5. Are Any Adjustment Mechanisms Damaged?
Check the hinges, swivel joints, and adjustment mechanisms for noticeable play, damage, or shifting.
6. Does the Wall Plate Stay in Place?
Make sure it:
- Sits firmly against the wall.
- Does not shift as the mount moves.
- Has no visible damage.
- Shows no surrounding cracks or shifting fasteners at the mounting points.
It is safer to have two people inspect and adjust a large TV, especially if the screen needs to be supported or repositioned during the inspection.
When the Problem Is the Installation
Sometimes the cause is the installation itself, rather than the mount’s mechanism.
Pay particular attention to the following factors:
Wall Type
Different wall materials require suitable mounting hardware. Do not assume that one hardware kit works for concrete, brick, hollow materials, and framed walls alike.
Installation Quality
Even a strong TV mount will not be secure if:
- The wrong hardware is used.
- The supporting surface is not strong enough for the load.
- The installation does not follow the manufacturer’s instructions.
Surface Condition
Cracks around the fasteners, movement of the wall plate, or a noticeable gap between the wall and the mount mean you should stop adjusting the screen and check the installation’s security first.
When to Replace the TV Mount
Sometimes adjustment alone is not enough. Replacement may be necessary if:
- The TV’s weight exceeds the mount’s capacity.
- The TV’s VESA pattern is not supported by the mount.
- The mount is damaged or deformed.
- The tilt mechanism no longer holds its position after correct adjustment.
- The screen continues to change angle on its own.
- The adjustment range does not suit your viewing setup.
When choosing a replacement mount, consider both the TV’s size and how you use it in the room.
If the TV will stay in one position, consider the FM6-B fixed TV mount, designed for large TVs from 43 to 85 inches.
If the screen is installed above eye level and you only need to adjust its tilt angle, a tilting TV mount is a suitable choice. For example, the TM6-B supports TVs up to 85 inches and lets you adjust the tilt angle without a complex swivel mechanism.
For rooms where you regularly need to extend the TV and turn it in different directions, a full-motion TV mount is more suitable. The ONKRON M6L-B offers tilt, swivel, and wall distance adjustment. For especially large screens, the range includes the M10-B, with a maximum weight capacity of 220 lbs.

How to Keep Your TV From Tilting Again
To help the screen stay in its intended position:
- Choose a mount that matches the TV’s weight, screen size, and VESA pattern.
- Follow the installation instructions.
- Position the VESA mounting rails symmetrically.
- Secure all required fasteners evenly.
- Do not use the screen as a handle when repositioning the mount.
- Leave enough cable slack.
- Inspect the mount periodically as recommended by the manufacturer.
A compatible TV mount that is in good condition and correctly installed should hold the TV in its intended operating positions without constant readjustment.

Common Mistakes
1. Choosing a Mount Based Only on Screen Size
Screen size does not determine a TV’s weight or VESA pattern. Check all three specifications together.
2. Overtightening Adjustment Screws
Excessive force can damage the threads or components of the mechanism. Follow the adjustment method described in the manual for your specific model.
3. Ignoring Increasing Play
If the misalignment or free play becomes more noticeable over time, investigate the cause before continuing to use the mount.
4. Repositioning the TV by Applying Force to the Screen
Move the mount as its design and instructions allow, without placing unnecessary stress on the TV panel.
5. Overlooking the Cables
Taut cables can restrict movement and put additional force on the screen.
6. Using Hardware Without Considering the Wall Material
The security of the entire setup depends on the mount, the supporting surface, and the correct installation method.
FAQ
Why does my TV keep tilting down?
Start by checking the tilt mechanism’s adjustment, whether the TV’s weight is within the mount’s maximum capacity, and how securely the screen is attached to the VESA plate. If the problem persists after correct adjustment, the mount needs a more detailed inspection.
Is it normal for the TV to change position when the mount is extended?
The force needed to move the mount may vary depending on the position of its arms, but the screen should not drift out of the selected position on its own. If it does, check the adjustments, weight load, and connections.
Can I just tighten the screws more?
There is no universal rule. Some screws adjust tension, while others secure components. Overtightening can damage the mechanism, so follow the manufacturer’s instructions.
Can a cable pull the TV out of alignment?
Yes. A cable that is too short or under tension can restrict the mount’s movement and put extra force on the screen, especially at the limits of its travel.
Why is one side of my TV lower than the other?
Possible causes include misaligned VESA mounting rails, unevenly secured fasteners, play between the TV and the mounting plate, or an error during installation.
When do I actually need a new TV mount?
Replacement is appropriate if the mount is incompatible with the TV’s weight or VESA pattern, is damaged, or no longer holds the screen in its intended position after correct adjustment.
Final Thoughts
If your TV starts tilting, you do not necessarily need to replace the mount right away. First, identify what has shifted: the screen, the mount’s mechanism, or the wall plate. Then check the VESA attachment, adjustment mechanisms, weight capacity, cables, and wall installation.
If the existing mount does not match the TV’s specifications or no longer holds the screen after correct adjustment, choose a suitable replacement. Browse the ONKRON TV wall mount collection to compare VESA compatibility, maximum weight capacity, and available adjustments, and find an option that suits your TV and viewing setup.
