Re: Vizio M70-C3 Half picture is bad, main board on its last leg?

Re: Samsung UN70NU6070 TV Issue - HELP!

Re: Vizio E601i-A3 top half of screen dim

Shopjimmy seems to show 2 backlight strips as replacement. Perhaps this tv has 2 led strips, one on top and the other on the bottom? Maybe one strip is burnt out?
