Our TV stuck in the up - closed position last year,. Or was it two years ago? Anyways, the problem was intermittent - sometimes it would operate okay and other times it would stick in the up - closed position. But, importantly, it always stuck in the up - closed position; never in the down - open position. When I raised the TV it sounded like something might have been out of adjustment... like a clunk sound right at the top when it became fully up - closed. After some tinkering I found that if I pushed the toggle switch with a bit of pressure to one side, then the TV seemed to open normally. From that I concluded the toggle switch was likely the problem. I replaced the toggle switch and it's never failed to operate since.
