Hello, good morning / afternoon / evening. I have a doubt the strw6554a and the strw5453 are the same? is that I have a sharp tv (model: 14t1-l) that uses the strw5453 but I don't have it and I want to try the strw6554a but doing a little research he has: strw5453 leg 7 the BB and the other strw6554a leg 7 has BD will be the same?
