Does Mounting a TV Void the Warranty?

Part of our complete guide: How to Mount a TV on Any Wall.

This one comes up a lot, usually with the TV still in the box. It is a fair question, because a new television is an expensive thing to put four bolts into, and nobody wants to find out later that they signed the warranty away to get it on the wall.

The short answer is no. Mounting a TV does not void its warranty, and the reason is sitting on the back of the set.

1. The Holes Are There on Purpose

Turn a modern television around and there are four threaded inserts in the back panel, spaced to the VESA standard. The manufacturer put them there, published the spacing in the manual, and in many cases sells a wall mount of its own that bolts into them.

Both of the brands we see most often give wall mounting instructions in their own documentation. Samsung's TV support guide walks through fastening the VESA screws; LG's owner's manuals tell you to use a mount and screws that meet the VESA standard. A manufacturer does not write installation instructions for something that forfeits its own cover.

So the act of hanging the set is not the problem. What the paperwork actually excludes is damage, and that is a narrower and much more useful thing to know about.

2. What the Manuals Actually Say

It is worth reading the words rather than the rumour, because they are quite specific about hardware.

Samsung's guide says to fasten all four VESA screws, not to use screws longer than the standard dimension because screws that are too long may cause damage to the inside of the TV set, and not to fasten the screws too firmly because that may damage the product. LG's manuals put it even more plainly: do not over tighten the screws, as this may cause damage to the TV and void your warranty, and any damage or injury caused by misuse or an improper accessory is not covered by the warranty.

Read together, that is one message. The mount is fine. The bolts are where the risk lives, and both makers are warning about the same two specifics: length and torque.

3. The Three Mistakes That Actually Cost You

Nearly every genuine warranty problem from a wall mount comes down to one of three things, and all three happen during the install rather than afterwards.

• A screw that is too long. The insert has a finite depth. A bolt that runs past it bottoms out against the chassis behind the panel, and tightening it from there puts pressure exactly where you least want it.
• Too much torque. Those inserts are set into a plastic housing on most sets. Over-tightened, they strip, crack the housing around them, or spin loose in it — and a stripped insert is not a thing you can put back.
• The wrong bracket. A mount below the weight rating of the screen, or one that is not to the VESA pattern the set uses, is the improper accessory the warranty language is talking about.

The length question is the one most people get wrong, and a longer bolt feels safer when it is the opposite. Our guide to what size screws a TV wall mount needs covers how to work out the right one for a given set.

4. The Mount Has Its Own Warranty

Worth separating clearly, because people conflate the two. A wall mount bought separately is its own product with its own warranty from whoever made it. LG's manuals note that a third-party mount is not covered by the television's warranty, which is simply saying it is not LG's product.

That matters in one practical way: keep the mount's paperwork and its hardware bag. If a bracket ever has to be claimed on, that is the document that does it, and the spare bolts in the bag are the ones matched to that plate. Our notes on reusing an old wall mount cover what to check when the bag and the manual are long gone.

5. Tilt, Ceilings and the Odd Installs

The manuals also set limits on how a set may be mounted, and they are more specific than most people expect. Samsung's guide advises against mounting a television at more than fifteen degrees of tilt, and warns that installing one on a ceiling or a slanted wall risks it falling.

That lines up with how a tilting mount works anyway: it angles the screen down a few degrees to deal with height or glare, nowhere near that limit. It is worth knowing about if a room is pushing you toward something unusual — a ceiling mount or a high or vaulted wall both change what the set is being asked to tolerate. Tell us what the room looks like and we will tell you what that spot takes.

6. What a Careful Install Does About It

All of the above turns into a short list of habits, and it is most of the difference between a set that is fine in ten years and one with a cracked insert.

• The bolt length the set specifies, taken from the manual rather than from the longest one in the bag.
• Spacers where the back is curved or recessed, so the bracket sits flat instead of being pulled into the housing.
• A mount rated above the weight of the screen, with the VESA pattern checked against the set rather than assumed.
• Snug, not forced. The bracket needs to be solid against the back of the set and no tighter.
• Safety screws engaged and cable slack checked, so nothing is under tension when the mount moves.

Every installation covers mounting the TV, leveling, basic cable management and all wall hardware. The mount itself is separate — flat $35, tilting $45, full-motion $125 for 32 to 55 inch sets as a special order — or bring your own and we will fit it at no mount charge if it suits the TV.

7. What to Have Ready When You Book

• The model number off the back or the box, which is what settles the VESA pattern and the weight.
• The hardware that came with the set, if there was a bag of bolts and spacers in the carton.
• Any mount you already own, so we can check it against the TV before the day.
• The manual, or where to find it online, if you want the figures read off it with you.

Installation is $129 on sets up to 55 inches, $139 at 65 inches, $229 at 75 and $279 on 85 inches and above. Service is free within 20 miles of Lexington, and Richmond is our home base so it is free there too.
