DIY TV Lift Cabinet: How to Choose and Install a TV Lift Actuator

A TV lift cabinet is one of the most satisfying actuator projects there is: press a button, the TV rises out of the cabinet; press again, it sinks away and the room looks like a room again. It is also a project where one measurement mistake — usually the stroke — turns a weekend build into a rebuild. This guide walks through the measuring, choosing, and installing in the order that avoids that mistake.

How a TV Lift Works

The idea is simple. A linear actuator mounted vertically inside the cabinet pushes a TV mounting bracket upward. When the actuator is fully retracted, the TV sits hidden inside the cabinet. When it extends, the TV rises through an opening in the top (or above a false top panel) into viewing position. When it retracts, the TV drops back down.

Two features of HyHaven actuators do a lot of the work for you: built-in limit switches stop the motor automatically at both ends of the stroke, so you do not need external limit switches for normal use, and the actuator holds position when power is off, so the TV does not drift down overnight. Your job is to get the geometry, the force, and the power right.

Step 1: Measure Before You Buy Anything

Measure three things, in this order, with the actual TV and mount in hand:

1. The lift height. Stand the TV on the mount the way it will sit in the cabinet. Measure from the TV's resting position (fully lowered, inside the cabinet) to its viewing position (fully raised). That distance is the minimum stroke you need. Then add clearance: the TV must clear the cabinet top opening with room to spare, and any cables must have slack through the full travel. Choose a stroke longer than your measured lift height — never exactly equal to it, because you need margin for the mount, the cable slack, and small build tolerances.

2. The cabinet interior. Measure the inside height, depth, and width. The actuator plus the mounting bracket, in its fully retracted state, must fit inside with the TV lowered. Also measure the top opening: it must be wider than the TV plus its mount, with clearance on both sides so the TV cannot scrape the cabinet on the way up.

3. The weight. Weigh the TV together with the mount and any bracket you will attach to the actuator. Do not guess this from the TV's box or a specification you half-remember — weigh the assembly you will actually lift. This number decides the force rating you need.

Write all three numbers down. Every choice below refers back to them.

Step 2: Choose the Actuator

Force. Pick an actuator whose rated force comfortably exceeds the weight you measured. "Comfortably" matters: a lift that runs at its force limit will be slow, will strain on any slight binding, and will have no reserve for a heavier TV later. Use the measured weight, add a sensible margin for the mount and for friction in the guides, and then pick the next force rating above that total — not the one that only just covers it.

For reference, HyHaven's force range runs from the U1 at 900N through the U2 at 1500N and the U11 at 3500N to the U3 at 6000N and the U6 at 7000N. Most TV lifts land in the lower half of that range once the real weight is measured — but let your scale decide, not a rule of thumb about screen size, because two TVs of the same screen size can weigh very differently.

Stroke. Pick a stroke longer than the lift height you measured in Step 1. If your measured travel is, say, just under a standard stroke option, take the next option up — the built-in limit switches will stop the actuator at the end of its stroke, and you set the raised and lowered positions with the mounting geometry, not by wishing the stroke were longer.

Speed and noise. Check the speed and noise figures on the specific model's product page (Full Specifications) rather than assuming. A TV lift does not need to be fast — a calm, steady rise looks better than a rushed one — but it should not be so slow that you are waiting on it. Noise matters more here than in a workshop project, because the lift runs in a living room: read the model's noise figure before buying, and do not assume all models are equally quiet.

Voltage. 12V or 24V both work for a mains-powered cabinet (you will buy an AC-to-DC supply either way). The main difference is current: the same model draws less current at 24V. Check the table in Step 4 and read our 12V vs 24V guide if you are torn.

Step 3: Plan the Mounting

A TV lift fails more often from bad guidance than from a weak actuator. The actuator pushes; it does not guide. If the TV can sway, twist, or rack sideways, it will bind — and a bound lift looks like a dead actuator when it is actually a geometry problem.

• Mount the actuator vertically, with its base fixed to the cabinet floor or a solid cross-member and its rod end fixed to the TV bracket. The push line should run through the centre of the TV-and-bracket assembly. An off-centre push twists the load and causes binding.
• Add guides. Drawer slides, linear rails, or a pair of guide rods on either side of the actuator keep the TV travelling straight up and down. The guides carry the sideways loads; the actuator carries only the vertical push. This is the single most valuable addition to a DIY TV lift.
• Keep cables in a loop with slack. Power and signal cables to the TV need enough slack for the full travel, routed so they cannot snag on the cabinet edge or the guides. A cable chain or a simple loose loop tied at both ends works; a taut cable does not.
• Leave access. You will need to reach the actuator, the control box, and the power supply again — for adjustment, for a fuse, or for a future TV swap. Do not seal them behind a glued panel. A removable back or base panel saves a future rebuild.

Step 4: Power and Control

Size the power supply for the actuator's full-load current in the voltage you chose — not the no-load current, and not a guess. Verified full-load currents:

Note the controller-kit caveat: HyHaven's Wired Controller Kit in its 24V version outputs 24V DC at 2.5 A, which covers small actuators (U1, U2) but not larger ones. For a larger lift actuator, feed the control box from a higher-rated supply matched to the table above. Our power supply sizing guide walks through this in full, and our wiring guide covers the rocker-switch, wired-controller, and wireless-remote options.

For a living-room cabinet, a wired pendant or a wireless remote is usually nicer than a fixed rocker switch — you can stand where you can see the TV while it moves. Whichever you choose, fit an inline fuse on the positive supply lead, rated above the full-load current.

Step 5: Install and Test in This Order

1. Build the cabinet frame and fit the guides first, before the actuator goes in.
2. Mount the actuator and the TV bracket, but do not hang the TV yet.
3. Wire the supply, controller, and fuse. Check polarity: if the rod moves opposite to the button labels, swap the two actuator leads.
4. Run the full stroke unloaded. Watch for binding, scraping, or cable snags through the whole travel. Fix the geometry now — it only gets harder with the TV on.
5. Hang the TV, then run the full stroke again under load. Check that it rises smoothly, stops cleanly at both ends, and sits level. Check that the top opening clears on both sides.
6. Only then close up the cabinet panels.

If the lift hesitates or stalls under load but ran fine unloaded, the usual suspects in order are: binding in the guides, an undersized supply (check the table), or a force rating with no margin. Work through them in that order before suspecting a faulty actuator.

Common Failures (and How to Avoid Them)

• Stroke too short. The TV never fully clears the cabinet, or it tops out before reaching viewing height. Avoided by measuring lift height first and choosing the next stroke up.
• Side load and binding. The TV twists because the push is off-centre or there are no guides. Avoided with centred mounting and guide rails.
• Undersized power. The lift crawls or stalls under the TV's weight. Avoided by sizing the supply for full-load current from the table.
• Cable snag. A taut HDMI or power cable catches mid-travel and either yanks a connector or stops the lift. Avoided with a slack loop and a test run before closing up.
• No access panel. A future fuse change or TV swap becomes a cabinet demolition. Avoided with a removable back or base.

FAQ

Can I use any linear actuator for a TV lift?

Any actuator with enough force, enough stroke, and a vertical mounting arrangement can work in principle — but check all three numbers against your measurements. Force without stroke, or stroke without guides, is not a lift.

Does the TV need to be perfectly balanced on the bracket?

As balanced as you can get it. A badly off-centre TV loads one guide more than the other and invites binding. Centre the TV on the bracket before you tighten anything.

Will the TV stay up if the power goes out?

Yes — the actuator holds its position when unpowered, so the TV stays where it was. It simply will not move until power returns.

Can I control the lift with a remote?

Yes. A wireless remote kit lets you raise and lower the TV from your seat, and the receiver handles the polarity reversing. A wired pendant is the alternative if you prefer a fixed control point.

What if I upgrade to a bigger TV later?

Re-weigh the new TV plus mount, and check the new total against your actuator's force rating with margin. If it still fits comfortably, only the bracket may need changing. If it does not, the actuator — not just the bracket — needs upgrading.

The Short Version

Measure the lift height, the cabinet, and the real weight. Pick force with margin and stroke with room to spare. Guide the TV straight, power the actuator for its full-load current, test unloaded before you hang the TV, and leave yourself an access panel. Do those six things and the lift will feel like furniture, not a project.
