Can one plug a 110v tv into a 220 v outletl without doing any damage?

I have a friend who brought her 110v TV from the US to Europe when a helpful neighbor plugged it straight into the wall. 220volts.



Is there any chance he did not damage it?



Is there any chance he only blew a fuse? Does this tv even have a fuse? I googled for a schematic for it, didn't find a schematic, but did find a video of someone checking that very model (I don't have the link handy), finding one of the soldered in fusible resistors to be blown, and replacing it. He didnt' say it was blown by 220 volts or give any reason why it broke. Believe it or not, I take a screwdriver and a VOM with me when I travel, and I'm willing to buy a soldering iron and solder, if that will do it. It would save her a lot of money, boost her image of me, and boost my ego.



It's a Toshiba 40RV525U made in 2008. 2008. 2.75 amps max.



She's not stupid at all but it's been months since this happened and I think she's forgotten some details. The story is that her cousin's friend checked it out and decided it was fine and just needed a transformer. Internal? I dont' think so, so he must have meant a 220 to



110 transformer** but I may not be able to talk to him directly becaause he's old and does not speak English. **But if that's it, why didn't my friend try it when she got the TV back. She says she has 2 of them for other appliances and just about any commercial step-down transformer will power 2.75 amps, right? I thought she said he took it apart, but now she says he didn't, so maybe he was just assuming it wasn't broken and giving the generic answer when people ask about 110 volt appliances. She's going to call him again, or maybe she said call her cousin.

She lives about 90 minutes from where I'll be. I expect to visit at least a ccouple more times anyhow, but I'd like to come prepared to do this in the minimum number of trips.

It sure does. That would be great if it were only the fuse. And by golly, the seller is in Baltimore!!!! That's where I live. Of course now the TV and I are 2000 miles away.

If it's worse than the fuse it would be worth buying the whole board for $40. He wants 10 for shipping but I'm sure he'd want more to ship to Europe. It would still be worth it. Tnx.

I'm sure he used an adapter. That's what I use for the laptop.

No, this was a 110 volt only tv, not -240. I know about 110 to 240, my laptop and my phone chargers are that. But this is from 2008 and it's

110.

Any chance he did not damage it?

That would be good.

The label on the back says 110 (or 120) I can't imagine it is designed to work with 240 and they didn't say so on the back.

European countries encode TV signals for either PAL or SECAM. U.S. countries (and TV's) use NTSC formatting. Without also using a HDMI converter (and they are not cheap), the picture is likely to be blurry at best and possibly not even watchable. I found this link, which may be helpful:

Many do, but if you read the start of the thread, you would think this one doesn't. :-)

Working on answer to Retired

I came back to this t hread to ask about 50 vs. 60cps. I had't thought about PAL vs. NTSC yet. A big problem. OTOH, since she struggles with any language other than English, maybe she plans to stream etc. and not watch local cable. I will ask her.

She had a lot of help available planning this move, and I'm sure she took advantage of it, but maybe this part was skipped or ignored or forgotten later, and she just brought this big "beautiful" tv.

This tv has both NTSC and ATSC. and QAM.

From what I was able to view in the page information portion of my browser, the original article was published in 2020 and edited in August of 2021. I wouldn't exactly call it "way" out of date; if it is, what does it make all of us? Fossils? I'm always interested in learning more. What specific information in this article is incorrect and what's the up to date correction?

That sounds good. I plan to let you all know what happens.

The TV they show is modern, but the rest of it is either out of date or out of touch or both:

"Yes, your TV will work in Europe as long as you have an adapter/converter to convert from 240 volts (Europe) to 120 volts (US). You can then stream content using apps on your TV. If want cable, you?ll additionally need an HDMI video format converter to convert the format to NTSC."

Convert HDMI to NTSC? What on earth for? Modern TVs have had HDMI input now for a long time and they don't have NTSC input.

"Ultimately three standards were born, and they are still with us today: NTSC, PAL, & SECAM.

Every country in the world uses one of these three standards, and therefore your TV was built to work with one of them.

In the United States we use the NTSC format, whereas Europe uses either PAL or SECAM."

That's wrong too. The US has been using ATSC for all broadcast for about fifteen years now. I'm pretty sure that a US TV isn't going to work to pick up over the air in Europe. What kind of output their cable boxes have over there and if it's compatible with HDMI on a US TV, IDK. Presumably you could stream over the internet just like you can here if the TV has that built-in or you have Roku, etc streaming device.

We lived in Germany from 2003 to 2008 courtesy of the Army. We brought an American TV which plugged into a transformer to convert 220 to 110, and it worked on the American Armed Forces stations via satellite. We also bought a German TV that could do all 3 standards and used it on the German satellite receiver.

I have heard that the Army is courteous.

There you go. I asked about this locally, not to electronics types but those who had moved from the US or knew someone who had, and a couple claimed there would be problems. Buy new!! There are always people saying to do that. And it seems always people saying, "It won't work".

and it worked on the American Armed Forces stations via satellite. We also bought a German TV that could do all 3 standards and used it on the German satellite receiver.

If the device is rated only for 110v - 120v and you plug it into a 220v - 240v source, unless some protective device quickly cuts off the power, you will probably quickly realize that you should not have done it. The results could range from quiet destruction to dramatic fireworks and smoke.

Yes, because the outlet clearly can accept the plug. Notice how a 120 or a 220 volt outlet looks different from a 240 volt outlet or a 125/250 volt outlet or from a 20-Amp 3-Phase outlet. A 120 or 220 volt outlet looks like it can accept the plug, so you can plug it in.

If the 120 or 1255 volt plug does NOT fit the 220volt outlet, then it won't work.

If 220V is actually present at the receptacle and the TV is only capable of 120V, it will either fry it or at a minimum blow the fuse. Presumably when one asks about plugging a 120V device into a 220V receptacle, they mean using an adaptor. Plus in the US it's 240/120, not

220.

I remember as a kit it was referred to as 110/220. It used to be.

Nominal US voltage was 110/220 until the 1930s when it changed to

115/230, and changed again in the 1960s to 120/240 which it has been since then. Some people are just resistant to change.

A lot of older people say 110/220. It seems to mean the same thing as

120/240. I've also heard 115/230, 117/234, 118/236, and 125/250 (always a 1:2 ratio),

BTW, I've measured it here. Almost exactly 120/240.

And, of course, 120/208 ...

Shouldn't you say "Don't ask" 3 times? ;-)
