The tv is a lg 39ln5700. The screen did have an image with the flash light test. At first we thought it was the power board. We replaced it with no difference.
After reading more here I found a way to test the LEDs to see if that was it. Yep.
Got the 4 strip pack and replaced the 2 bad strips. Before reassembling check to see if it worked. Yep we have light. Reassembled the tv, turned it on and a bunch of vertical lines. Brighter strip in the middle.
Check the ribbon cables and the ends were damaged. Got replacements for those. No difference. Read some more, may be a bad t-con board. Got one of those. Now we have a black screen no image with flash light test.
So now what? It's frustrating that it had an image before we took it apart and now it doesn't. I'm looking for some help.
