Buying a Second-Hand TV in Australia: The In-Person Inspection Checklist

A used TV off Facebook Marketplace or Gumtree can be a genuinely good buy. A two or three year old panel that cost well over a grand new often sells for a few hundred dollars, and TVs do not wear out the way a phone battery does. The catch is that you have to test it in person, because a private sale gives you almost no safety net if it turns out to be faulty.

Here is the part most people miss. When you buy privately from another individual in Australia, the Australian Consumer Law consumer guarantees that protect you in a shop do not apply the same way. A private sale is largely buyer beware. There is generally no automatic right to a refund, repair or replacement if the screen dies a week later, and no warranty unless the TV still has manufacturer warranty that transfers to you. Once the cash changes hands and the seller drives off, the problem is yours. That is exactly why the inspection below matters so much: your inspection IS your warranty.

(One distinction worth knowing: if you buy a used TV from a business or a second-hand dealer that sells in trade, ACL consumer guarantees can still apply, because it is a business sale. Our guide to TV warranties and the ACL covers how that works on retail purchases. The buyer-beware rule here is specifically about buying privately from another person.)

So treat every private used-TV purchase as final, and never buy one you have not seen powered on. Work through the checklist below before you agree on a price.

Before you go: what to bring

Turning up empty-handed means taking the seller's word for it. Bring the gear to test it yourself:

• Your own HDMI cable, so a dead port cannot be blamed on "a dodgy cable".
• A phone, laptop, or games console as an HDMI source to prove each port works.
• A USB stick with a few full-screen solid-colour images on it (black, white, red, green, blue) plus a photo or two. This is your dead-pixel and backlight test.
• Cash, counted, and ideally the exact amount once you have agreed.
• A second person if it is a higher-value set or an unfamiliar location.
• The TV's model number if the seller has listed it, so you can look up what the same or an equivalent model costs new before you go.

Give yourself time. A seller who rushes you or will not let you run these checks is telling you something.

Step 1: Confirm it powers on from cold

Ask for the TV to be switched off at the wall before you arrive, or turn it off yourself and unplug it for a minute. Then plug it in and power it up while you watch.

A TV waking from standby can hide a fault that only shows on a true cold boot, like a power board that struggles to start or a backlight that flickers on start-up. If a listing says the power is disconnected, it cannot be demonstrated, or the seller only offers to show you a photo of it working, walk away. "Works but I can't plug it in right now" is the oldest dodge in the book, and there is no way to verify it. Never buy a TV you cannot see fully powered on and running.

Step 2: Check the panel for faults

The panel is the expensive part and the one thing you cannot fix cheaply. Run these while it is on:

• Dead or stuck pixels. Put up each full-screen solid colour in turn (black, white, red, green, blue). A dead pixel shows as a tiny black dot that stays dark on every colour. A stuck pixel stays one colour (a red, green or blue dot) when the rest of the screen changes. One or two can be hard to spot from the couch but obvious up close, so get near the screen.
• Vertical or horizontal lines. A solid colour makes any thin coloured or dark line running across the panel stand out. Lines usually mean a failing panel or a loose internal ribbon connection, and that is generally not worth repairing on a used set.
• Backlight clouding and flashlighting. On a full-screen black image in a dim room, look for uneven grey patches, brighter blotches, or bright pooling in the corners. Some unevenness is normal on cheaper LED sets, but obvious cloudy patches or corner "torch" glow (often called flashlighting or dirty-screen effect) are worth knocking the price down for, or walking away from.
• A quick moving image. Play a video and watch for stutter, colour flickering, or sections that lag behind. This catches processing and panel faults that a still image will not.

If it is an OLED, add a burn-in check

OLED panels look great but can suffer permanent burn-in, where a static element like a news ticker, channel logo or game HUD gets faintly etched into the screen. On a used OLED this is the single most important thing to check. Put up a full-screen mid-grey or a solid colour and look hard for any faint ghost of a logo, bar or menu. Also try a plain white screen, which tends to reveal retention. Our explainer on OLED burn-in and image retention covers what causes it and how to tell temporary retention from permanent burn-in. On a private sale there is no coming back from it, so if you see a ghosted logo, that TV is worth a lot less than a clean one.

Step 3: Work out the age and usage

A cheap TV is only a bargain if it is not on its last legs. Two things tell you how much life is left.

• Model year. The model number encodes the year the TV was released. Learning to read it tells you whether you are looking at a recent set or something closer to a decade old that is near the end of its panel and software support. Our guide to decoding Australian TV model numbers walks through how each major brand structures theirs. A sticker on the back usually carries the full model and serial number.
• Panel hours. Some TVs expose an internal usage counter or panel-hours reading in a hidden service menu. If it is available it gives you a rough sense of how hard the set has been run. Be realistic here: service menus vary a lot by brand, are not always accessible, the reading is not always present or reliable, and poking around in the wrong setting can change calibration or other options you did not mean to touch. If you are not confident, leave the service menu alone and lean on the model year and the visual checks instead.

Step 4: Test every input and the remote

Ports fail, and a TV with one working HDMI is a lot less useful than the listing suggests.

• Every HDMI port. Plug your own source into each HDMI socket in turn and confirm you get a picture and sound from all of them. Do not accept "they all work" without seeing it. HDMI ports are a common failure point and a hard one to repair.
• USB ports. Plug your USB stick into each USB socket and confirm the TV reads it (this is also how you display your test images).
• The antenna tuner, if you will use free-to-air. Ask the seller to run a channel scan, or check for tuned channels, so you know the tuner works.
• The remote, every button. Step through power, volume, channel, input, the direction pad, and the menu button. A common trap is "works but no remote". Some brands have a phone app that can control the TV, and universal or replacement remotes exist, but neither is guaranteed to cover every function on every model, and smart-TV setup can be painful without the original remote. Treat a missing remote as a real cost and a reason to pay less, not a minor detail.

Step 5: Make sure it is logged out and factory reset

A used smart TV can still be tied to the seller's accounts, which locks you out of streaming apps and, on some sets, ties the TV to their Google, Samsung or LG account. Before you pay:

• Ask the seller to sign out of their streaming logins (Netflix, Stan, Disney and so on).
• Have them run a full factory reset, or do it together, so the TV starts fresh for you. This clears their accounts and settings.
• Confirm it boots into first-time setup afterwards, which proves the reset actually took.

Doing this in front of the seller also confirms the smart platform still works and has not been abandoned by the manufacturer, which happens on older sets.

Step 6: Sanity-check the asking price

A used TV with no warranty and no returns should be a clear discount on the new price, not a small one. The way to judge that is to know what the same model, or a current equivalent, costs new today.

TV Rex tracks live new prices from Australian retailers, so before you agree on anything you can look up the seller's model or a comparable current one and see what new actually costs right now. We do not stock or sell TVs; we track and compare prices, which is exactly the reference point you want. If a three year old set is being sold for not much less than a newer equivalent goes for new (with a warranty and consumer guarantees behind it), the used one is overpriced. As a rough guide, the older the panel and the closer the used price creeps to new, the less the deal makes sense.

Step 7: Buy safe and avoid the scams

Most sellers are ordinary people offloading a TV. A few are not. Watch for these:

• Possibly stolen goods. Be wary of a listing with no box, no accessories, no reason for selling, or several identical TVs from the one seller, especially paired with a cash-only rush. Ask why it is being sold. A vague or impatient answer is a flag.
• The "can't demo it" dodge. Covered above and worth repeating: no power, no antenna, no remote, "just take my word for it". If you cannot see it running, do not buy it.
• Meet safely. For most pickups, go in daylight, take someone with you, and inspect at the seller's home rather than a random car park where you cannot check much. For higher-value sets, many Australian police stations offer a safe-exchange zone or car park for private sales; a public, well-lit spot is the fallback. Pay cash in person, and only after you have inspected and tested the TV. Never pay a deposit to "hold" a TV you have not seen.

Run the whole routine, in order, before any money moves. It takes ten minutes and it is the only protection you get on a private sale.
