I was mistaken about being inside my manufactured warranty period. I looked it up and I had purchased the tv last JUNE.
He said that there is a way to tell if the back cover has been removed. Instant warranty void. But if you are outside of warranty there is really nothing to the removal to check the issue. Take ALL the screws off the back and 2 from the bottom near the mount. If it is the first time for removal the back will need to be jiggled a bit to get it to come off. The inside is basically hollow. The main board is basically a 6x6 board. The harness is 12-14" long and goes to the PSU which is even smaller than the main board. There is also 3rd board which I imagine is related to ethernet and back panel connections. That is it it. I was quite suprised to see so little.
