U.S. Purchased Samsung TV
 
Partially related to earlier thread but different enough to warrant its own I believe. Apologies in advance if not different enough.

I have a curved UHD 3d Samsung that I do not want to replace. It says 120 v input on rear info plate. Many AV forums have talked about the power supplies bring universal since they are converting to DC internally, but they do not disclose that they are the same.

I took off the back panel to check it out and it had the input information in Chinese, and my rudimentary translation skills could not determine the input ( I do know my numbers)

When looking up the part number for the inverter board , I see them for sale throughout the world including english(UK) and German eBay sites. Usually stating removed from working tvs with crack screens, but no mention of them being a particular voltage.

Anyone have any definitive knowledge?

(Yes, smart guy answer is plug it in and see if it pops)

I checked the Samsung website (click on full specs) and the input is ONLY 110-120v (made in Mexico for the NA market) so don't try it with 220v. The previous response gives you some possibilities on the transformer.

Thanks-

(I still can't seem to be able to formally thank in this forum-maybe not enough posts?)


I do have a few step down transformers but if not needed for this device I wouldn't use it.

You are welcome. Since you have more than 10 posts you should see the thanks button on the bottom right of each post. If not, you might want to see with one of the mods.

I know the specs say 120. But I did ask a seller that had these boards for sale and he said the boards were marked input 110-240. Might be on the back that is not visible when installed. Most companies try to minimize parts in supply chain and will use common components wherever possible.

I am a bit surprised that it isn't dual voltage. I suspect that it isn't the parts cost (probably a difference of pennies per device), but rather the cost of getting approval. CSA and UL are one thing, but all the rest of the world another. It may even be dual voltage, but they didn't get approval for all the non 120 areas of the world. Best to use a Trafo.

Samsung makes many models that are only sold in NA. They usually are manufactured for the likes of Walmart and Costco and even though they share a 'series' number (5xxx, 6xxx etc) with a regular retail model, they are usually made with cheaper components and have fewer features...like dual voltage.
