I put a Samsung newer 40” tv in mine. They have a smal thin frame. Coming home from AZ we were on a pretty rough road. When we got home there was a thin line running from top to bottom in the middle. Loss of pixels. It got worse, when doing a search I found that there are ribbon connectors running along the bottom and can come lose. I squeezed the lower frame with my hand and the lines went away. I took it apart and could find no loose ribbons. I ended up putting a clamp on the frame, not pretty but pixel lose went away. I blame all this on the new TVs having this thin frame and have less support then the older ones. I would suggest putting a strap around the middle of the tv top to bottom to minimizing this to happen.
