Is It Safe to Buy a Used TV? 6 Checks Before You Pay
A used or open-box TV is usually a safe buy if you test the screen, check OLED wear and get the warranty terms in writing. Here are the six checks.

Yes, buying a used or open-box TV is usually safe, and it is one of the easier things to check before you pay. A TV either shows a clean picture or it does not, and most sets have a built-in test that makes faults easy to see. The real risks are three: a panel fault you did not test for, wear on an OLED screen, and a TV that tips over once it is home. Six checks, about ten minutes, cover all three.
A used TV hides very little if you test the screen, ask about its hours and anchor it at home.
If you are still deciding between "open box", "refurbished" and "used", start with our guide to what those labels actually mean. The checks below work for all three.
Is it worth buying an open-box TV, or a second-hand one?
It can be, because a TV has few moving parts and the most likely problems show up right away on the screen. What you are really buying is the panel, and the panel is exactly what you can test in person.
The question to ask is not "used or new?" but "what am I giving up, and is the saving worth it?" Here is a simple way to think about it:
| What you are buying | What usually comes with it | What to ask before paying |
|---|---|---|
| Open box from a store | Often the box, remote and stand; a store return window | How long is the return window, and is there any warranty? |
| Refurbished | Some warranty, usually written | Who gives the warranty, the maker or the seller, and for how long? |
| Used, from a person | Whatever they hand you | Can I watch it working first, and is the remote included? |
A good open-box or used TV comes with its remote, its stand or feet (with screws), and a power cord. Each missing piece is a small extra cost, so count it in before you agree on a price.
How do you test a used TV screen for dead pixels and lines?
Use the TV's own test first. Many brands build one into the settings. On recent Samsung sets, for example, Samsung's support page gives the path as Settings, All Settings, Support, Device Care, Self Diagnosis, then Picture Test. The TV shows a sharp test photo that you examine for flaws. Samsung says that if the test picture looks fine, the problem is probably a cable or a connected box, not the TV. If the fault shows on the test picture, or comes and goes, it may be a hardware fault.
Then do your own check, which works on any brand:
- Plain colours. Show a full-screen white, then black, red, green and blue picture (a phone or laptop on screen-share works, or search "solid colour test" on the TV's video app). Look for tiny dots that stay black or stay one colour.
- Lines and bands. Look for straight lines running top to bottom or side to side. They do not go away with a different cable.
- Dark scene. On a black screen in a dim room, look for bright patches at the edges or in the corners.
- Every input. Plug something into each HDMI port you plan to use. A dead port is easy to miss and annoying later.
- Sound. Turn the volume up and down. Listen for crackle or a buzz.
Wipe the screen gently first. A speck of dust can look like a dead dot.
Does an OLED TV wear out? What about burn-in?
OLED screens can keep a faint ghost of an image that stayed still for a long time, such as a news ticker, a channel logo or a game's health bar. LG's own reliability page calls this image retention and says it happens outside normal viewing conditions, not during ordinary use.
LG also explains how its sets look after themselves, which tells you what to ask a seller. Its Pixel Refresher runs by itself after the TV has been on for more than four hours in total and is then switched off. After 2,000 hours of use, which LG describes as about five hours a day for a year, a longer run of about an hour happens after switch-off. LG says vertical lines on the screen during that run are normal, not a fault.
So for a used OLED:
- Ask how it was used. A TV that sat on one news channel all day is a bigger risk than one used for films.
- Show a plain grey screen. Ghost shapes of logos or boxes show up best on mid-grey.
- Ask whether it was a store display model. Those often ran the same demo for long days.
LCD and LED sets do not get burn-in the same way, so for those the plain-colour test above is the main check.
What warranty comes with a used TV in DC, Maryland and Virginia?
Ask for the warranty terms in writing, and keep the receipt. The FTC's warranty brochure says almost every purchase carries an implied warranty under state law, meaning the product should do what it is meant to do, unless it is sold "as is". That brochure lists Maryland and the District of Columbia among the places that do not allow "as is" sales of this kind. Virginia is not on that list.
Maryland's own law says it plainly: wording from a seller of consumer goods that tries to remove the implied warranty that a product works is unenforceable. That is the general rule, not advice for your case. For a dispute, your state or DC consumer protection office is the right place to ask.
The FTC brochure also suggests checking who provides repairs, whether a heavy item must be shipped back at your cost, and whether the original box is required. For a big TV, those details matter more than the length of the warranty.
What should you do once the TV is home?
Two things: reset it, and anchor it.
Reset it. A used smart TV may still be signed in to the last owner's streaming accounts. Do a full factory reset before you sign in to anything. Our smart device reset checklist walks through it. It is also worth looking the model number up in our guide to checking for recalls before buying used.
Anchor it. This is the safety step most people skip. In its 2022 report, the U.S. Consumer Product Safety Commission said that since 2000 there had been 581 tip-over deaths involving furniture, TVs or appliances, and 472 of them were children. A television was involved in 71% of the child deaths. The same report estimated about 22,500 emergency room visits a year from tip-overs over 2018 to 2020.
The good news from that report: tip-over injuries fell 55% from 2011 to 2020, mostly because fewer people were hurt by TVs. The agency says most anti-tip kits cost under $20 and take under 20 minutes to fit. If you cannot anchor it, put the TV on a sturdy, low base and push it as far back as it will go. Keep remotes and toys off the stand so children are not tempted to climb.
The six checks, in one list
- Run the TV's own picture test, if it has one.
- Show plain white, black, red, green and blue screens and look for stuck dots and lines.
- Try every HDMI port you will use, and the sound.
- On an OLED, show a grey screen and ask how it was used.
- Get the warranty and return terms in writing; keep the receipt.
- At home, factory reset it and anchor it to the wall.
The bottom line
A used or open-box TV is a safe buy when you can see it working first. Test the screen, ask about OLED hours, get the terms on paper, and spend the small cost of an anchor kit. If a seller will not let you turn it on, walk away.
