I recently acquired a what I beleave is a 2012 Vizio model # M3D550SL 55" Smart Tv. Everything works fine, and even picks up a few more channels that my other TV's. The prob Im having is with the Backlight. From what Ive been able to dig up is that it is a Edge Lit screen. What Im trying to do is decipher weather it is the Led Strips, or if it may be the Led Driver Board? I will include a few pics, and wondering what other peoples thoughts might be on this. Thanks in advance.

We don't have Vizio branded TV's here in the UK.
