Is a used Sanyo TV worth buying? Which older sets still make sense, plasma burn-in risk, old smart TV apps, a 10-minute test, and fair used TV prices.

A used Sanyo TV is worth buying only when it's close to free, because a brand-new budget 4K set now costs less than most people expect. The same logic covers every older TV you'll find secondhand: plasma sets (which nobody has made since 2014), early smart TVs, and budget brands like Insignia, Element and Onn. Some of these are genuine bargains. Most are worth less than the seller thinks.
I help people buy and sell big, heavy things for a living, and TVs are the category where I see the widest gap between asking price and real value. In this guide I'll cover which older sets are still worth it, whether plasma burn-in is a real risk, what happens when an old smart TV stops getting apps, how to test any used TV in ten minutes, and what to pay for a 50 to 65 inch set by age and panel type.

A used Sanyo TV is worth buying for a spare room, a garage or a kid's room if it works perfectly and costs very little. It's not worth paying real money for, because Sanyo was a budget brand and newer budget sets beat it on picture and software.
Some background helps. Sanyo was a Japanese electronics company that Panasonic absorbed around 2010. In the US, later Sanyo-branded TVs were built by Funai under a license deal and sold mostly through Walmart. Funai also made sets under names like Magnavox, Emerson and Philips. So a Sanyo TV from the last decade is a Funai budget TV with a familiar badge.
That matters for two reasons. Parts and support for these sets are thin, and Funai went through bankruptcy proceedings in Japan in 2024. If a used Sanyo breaks, you're not getting it fixed. You're replacing it. Price it that way.
Where a used Sanyo TV makes sense: it's a working 32 to 50 inch set, it's cheap, and you plan to plug a streaming stick into it anyway. Where it doesn't: anyone asking near new-TV money because "it's a Sanyo." I've seen older Sanyo sets listed for hundreds of dollars more than a new 4K TV of the same size. Skip those.
No budget TV brand is reliably better than another on the used market. What separates a good cheap TV from a bad one is the panel age, the backlight and whether the smart software still works, not the logo.
Here's how I think about the common budget names:
| Brand | Who's behind it | Used verdict |
|---|---|---|
| Sanyo (US, recent years) | Funai, under license | Cheap spare-room TV only |
| Insignia | Best Buy's house brand, often with Fire TV or Roku built in | Fine if the built-in software still updates |
| Element | Budget brand sold through big-box stores | Basic picture, price it low |
| Onn | Walmart's house brand, many with Roku built in | Fine and easy to reset |
| TCL or Hisense (mid and upper tiers) | Major panel makers | The used budget sets actually worth hunting |
If you have a choice, a two to four year old mid-range TCL or Hisense beats any older budget set at the same used price. I covered that tier in depth in my guide to buying a used Roku TV, since most of those sets run Roku.
A used plasma TV is a good buy only for a picture enthusiast who wants deep blacks and smooth motion and doesn't care about 4K, HDR or power use. For everyone else, a cheap new LED TV is the better pick.
Plasma had real strengths. The best ones, like Panasonic's VT and ZT series and Pioneer's Kuro line, had black levels and motion handling that budget LED sets still struggle to match. Enthusiasts still hunt for them. But every plasma tops out at 1080p, none support modern HDR, they run hot, and they draw far more power than an LED set the same size.
Burn-in is a real risk on a used plasma. Static images, like a news ticker, a channel logo or a video game health bar, can leave a permanent ghost on the screen. Some light image retention fades after a few hours of varied content. Permanent burn-in doesn't. So when you test one, put up a solid gray or white screen and look closely for faint shapes. If you see a logo shadow, walk away.

Two more plasma quirks. They're heavy, often much heavier than an LED set of the same size, so plan for two people. And it's widely recommended to move them upright, never flat, because the glass panel can crack under its own weight.
Many older smart TVs don't. Streaming services and TV makers periodically drop support for older models, and when that happens apps stop working or vanish from the store. The fix is a cheap streaming stick in the HDMI port.
Early smart TVs from roughly 2010 to 2016 are the most exposed. Their processors are slow, their app stores are frozen, and some apps have already been pulled. You'll see this when a seller says "Netflix used to work on it." It probably did.
Here's the thing, though. It barely matters. A streaming stick costs less than a nice dinner, plugs into any HDMI port, and gives you current apps and a fast interface. When I look at an older smart TV, I treat it as a monitor with speakers. If the panel is good, the software is a solved problem.
What does matter: make sure the TV has at least one working HDMI port, ideally two. Very old sets with only component inputs aren't worth taking home.
Turn it on, show a plain white screen and a plain black screen, test every HDMI port, and check the remote. Those four checks catch nearly every expensive problem on a used TV.
If the TV has sound but no picture, shine a flashlight close to the screen. If you can faintly see the image, the backlight is dead. On a budget set, that repair usually costs more than the TV is worth.
Stripped mounting holes, cracked corners and pressure marks on the screen are the signs a TV was mounted badly or dropped. Check the back and the edges before you check the picture.
Look at the four threaded holes on the back where a wall mount attaches. Stripped threads, cracked plastic around the holes, or screws that are snapped off inside mean someone forced the mount. That can put stress on the panel behind it. Then run your hand around all four corners of the frame. A dented or cracked corner is the classic sign of a drop, and panels damaged that way often fail weeks later.
Finally, look at the screen from an angle with a light on it. Pressure marks show up as faint circles or rainbow patches that don't match the picture. If the stand feet are missing, ask why. Usually it's because the TV lived on the wall, which is fine. Just confirm the mount holes are clean.

A used TV should sell for a share of what the same size and tier costs new today, not what the seller paid years ago. TV prices fall every year, so the original receipt is almost meaningless.
Before you look at any listing, check what a new TV of the same size costs at a big-box store right now. That's your ceiling. Then:
The bigger the screen, the more a used TV saves you. A 43-inch used set barely beats a new one. A used 65-inch mini-LED for the price of a new 55-inch budget TV is a real upgrade. Getting a 65-inch home is the other problem. It needs to ride upright, padded and strapped, and it won't fit in most cars. On Commonplace, we handle pickup and delivery, the TV is inspected at pickup, and you see it working before you pay. Here's how buying on Commonplace works.

In the US, recent Sanyo TVs were made by Funai under a license and sold mainly at Walmart. Sanyo itself became part of Panasonic around 2010.
Many still run today, more than a decade after the last ones were made. The bigger issues on a used plasma are burn-in, heat and power draw, not sudden failure.
Light, temporary image retention often fades after a few hours of varied content. Permanent burn-in can't be fixed. Test with a solid gray screen before you buy.
Often yes, if the panel is good and the price is low. Plug in a streaming stick and the app problem disappears.
No. Keep it upright on its long edge, padded with a blanket, and strapped so it can't tip. Laying it flat lets the panel flex over bumps.
