A:AnswerI didn't know which cord to purchase either but is recommended that you take a picture of the back of your TV or product and show the Best Buy representative that picture and they will let you know whether to get polarized or nonpolarized
A:AnswerFollow-up: I bought 2....one each of different polarities. I returned the one I didn't need. (The TV will accept either 2 round or one round/one square plug.)
A:AnswerLook at the rear of your tv where the power cord goes in, there are 2 kinds, polarized and non polarized. Polarized has a flat bottom of the figure 8 shape, non polorized does not, this is the polorized cord.
A:AnswerI needed a new cord for my t.v. It was the right shape to fit so I thought I would try it knowing if it didn't work I could return it. My t.v. Is a different brand but I t works just fine.
