Used TV Buying Checklist

A TV screen can hide a lot of problems until you actually look for them. Run through this checklist before handing over any money for a used TV.

  1. Check for dead pixels with solid color screens

    Display full-screen white, black, and red screens and look closely for any pixels that stay dark or any stuck, discolored spots.

  2. Check backlight uniformity

    On a dark or black screen, look across the entire panel for patches of light bleeding through unevenly, especially near the edges and corners.

  3. Check for image retention (burn-in)

    On a solid gray screen, look for a faint ghost of a logo or a previously displayed image. This is burn-in, and it is worth checking especially carefully on OLED sets.

  4. Test the HDMI, USB, and smart features

    Plug a device into every input port to confirm it is recognized properly, and check that the remote and smart features like streaming apps work as expected.

  5. Check total usage hours if available

    Some TVs let you check cumulative on-time in the settings menu or a hidden service menu, which can give you a rough sense of how heavily it has actually been used.

A screen can look perfectly fine until you check it properly

Dead pixels, faint backlight bleed, and early-stage burn-in are all things a screen displaying regular content will hide from a casual glance. Running through solid color test screens takes only a few minutes and reveals problems a seller might not even know about.

OLED and LCD panels fail in different ways

OLED panels are especially prone to burn-in from static images like channel logos or a paused video, while LCD and LED panels are more likely to develop backlight bleed or dead pixels. Knowing which panel type you are looking at helps you know exactly what to check for.

Frequently Asked Questions

Is a small amount of backlight bleed normal on every TV?

A very faint amount of light bleed at the extreme edges is common on many LCD panels and usually is not a dealbreaker, but noticeable bright patches spreading across a dark scene are a legitimate reason to negotiate the price or walk away.

How do I check total usage hours on a TV?

The exact menu path varies by brand, but it is often found under a settings, support, or self-diagnosis menu, sometimes labeled as a hidden service menu. Search the specific model number online for the exact steps.
