Hey. I moved overseas recently, and took my DX930 with me. Of course I bought a 220V to 110V converter and was using that to power up the receiver and it's been working fine. However, yesterday, by mistake, somebody plugged it in directly to a 220V outlet, and now it's not working. No sign of life whatsoever. I hope it has some kind of protection against this but I am not sure (fuses, etc). Any suggestions ?
I don't know for sure, but I suspect that if you open it up, there should be a fuse near the power supply portion of the unit. It may have taken the hit for you and can perhaps be replaced easily.
(As a disclaimer... be sure the unit is not plugged in when you open the case! And only replace the fuse with another of equal rating.)
If it's not a fuse, then you probably smoked the primary winding of the transformer. If it got past that, you may have popped the rectifier and/or capacitor(s) in the power supply.
A 6ya expert can help you resolve that issue over the phone in a minute or two.

Since this unit dose not come with power adaptor. It has direct plug in in to the port behind the sub-woofer unit and other end to the wall outlet. Is there any way to convert the power supply from UK to US (220v to 110v). For example Desktop PCs have a switch behind every desktop unit to change power from 110v to 220v or vise versa. Anyone has any idea how to make this happen in Bose Companion 3 system. I bought it from UK and now moved to US and I want it to work in US. othervise use waltage adapter to use it
If you want to fry your electronics or appliances that's it's a sure way to accomplish that.
While appliance working ONLY at 220v will just not work or under perform (like a hair drier) when plugging electronic equipment that runds ONLY at 110v then that item will be "fried" as all its electric components will be burnt as it will receive twice the power that it was build to receive. Should that happen the safety switch on the 220v circuit where the item was MISTAKENLY plugged will be triggered (hopefully or there will be risk of fire and serious injuries, even death) and the power will be shut off. That's a major but possible mistake.
If traveling abroad those who come to US will unlikely damage their appliances (like electric razors) as they will receive less power (110v vs 220v) and usually these items are protected against these mistakes by the specifications of their own design. The opposite is not true of course as just mentioned above.
So do not play around with dangerous items please! ;)
On a positive note though: Nowadays most appliances have dual power and should work whether plugged in a 110v, 60Hz (most common in US) or 220v 50Hz (most common in Europe). So nothing really happens... it just works as long as you have the proper adapters to plug the appliance to the different receptacles.
Note: One of the differences is that (without going into the math of it all), an appliance working at 110v will draw x2 times the power than it draws when working on 220v so if an appliance was drawing 3A at 110v it will only draw 1.5A when working at 220v.
I can not respond to the warranty issues. My kitchen aid mixer is past warranty as well. I live in a country that uses 220V and my kitchen aid mixer is 110V. I have been using my kitchen aid mixer for almost 4 years with no problems at all.
The converter boxes are supposed to blow the fuse on the converter before it reaches your appliance and cause any problems.
If you purchase a 220V kitchen aid (although it would cost more money) it would probably have more power because of the higher voltage.
You burned the Power supply you don't need to switch motherboard out just knew power supply. And in the future there is a switch located on the back of them that will make them a 220v powersupply. But usually only a high end PC for gamers will need that so just put in a new powersupply and you should be good
Good day mate, no problem you can plug your dvd direct to your outlet since it indicates 100 - 240V it only means your player is capable of having either 110V 0r 220V.
note: also try to check 1st if you will see a voltage selector at the back of your dvd player. it's either a slide switch indicating 110 or 220V. if no sign of this selector no problem you can plug your player straight to your socket.
You have damaged the system beyond economical repair. There are so many components inside that have fried that it is impossible to repair. Sorry. That's what happens when you overvolt an electronic circuit.
