A:AnswerYes! Either the Wii composite or component cables will work with this TV. It only has one input that serves as both composite/component so you could not use two devices that require those inputs at the same time.
A:AnswerThe exact weight of the TV I am not sure of but if I was to estimate it doesn't weigh more than 50lbs. If anything it most likely weighs anywhere between 25-30lbs. I carried heavier chihuahuas.
