VIZIO E701i-A3 – Screen flashing like strobe light

Subject: VIZIO E701i-A3 – Screen Flashing VIZIO 70” TV Model E701i-A3 I am trying to repair a Vizio E701i-A3 LED TV. When I got the TV (used) it worked properly but there was a dark triangle at the bottom middle of the screen. I diagnosed it as a faulty LED backlight and ordered a new one. Once that was replaced and the TV put back together is when I started having these serious issues... After reassembly, I powered it on I would get the Vizio symbol on the screen for about 1 second and it would go off (the screen looked perfect for that 1 second or so that it would stay on). I ordered the complete set of boards from shopjimmy.com. This came with all the cables and boards needed. After replacing them, the TV now flickers like a strobe light and nothing is displayed on the screen except the flashing lights. I also hear a "static" (electrical) noise from the main power board. Please advise on what I should try next before I need to trash the TV and return the parts. Here is a video that shows the problem: https://youtu.be/TwWBRQlSlEk
