Samsung UN46D8000YF, Sony 55-in. UN55RU7100F, Samsung XBR=55X850D and Sony XBR-43X800H are all listed at 100V. Are they dual voltage?

LuAnn Jensen hard to give a specific answer. By checking the power boards it appears as if those are as follows: Samsung UN46D8000YF power board BN44-00430 Dual voltage Samsung UN55RU7100F power board BN44-000932N Dual voltage Sony XBR-55X850D use a 19.5V 8.21A-9.23A AC adapter. It should have a label on it that states 110/250V if so, it is dual voltage. If not you just need to get one that uses the input voltage for whatever country you are in. All you need is an adapter that tolerates the different voltages Sony XBR-43X800H commonly uses a AC 100- 240V 50/60Hz, 1.7A DC 19.5V power adapter. It should have a label on it that states 110/250V if so, it is dual voltage. If not you just need to get one that uses the input voltage for whatever country you are in. As you can see the Sony’s are easys because of the AC adapter. The Samsung not so since you would really need to make sure the power boards are right. Going by my experience with Samsung, I am certain you have those power boards I listed above.
