Hi Teckman, if you're still checking this post. These do suffer from display panel failures. If you disconnect the wide top flexi cable from the main board and turn the TV on, I believe the connected 1/2 of the display will still give a picture. If it gives a clear picture, you likely have a faulty display panel. You can't do the same with the second flexi because the TV won't work with it out.
Did a smaller MU6100 taday and I was able to repair it with the "tape cut-off" method. There are a few videos on you tube describing this.
