I don't know how this turned into a double post. I wanted to add the model name to the post. I suppose I did something wrong. The first time I tried to post it made me retype the entire post.

LCD displays a 2nd image slighty offset vertically. And multiple pairs of black lines along the bottom. Probably common as google "TCL 49S405 double image" pulls up this ifixit post ( link ) with identical ( nearly, but their fault seems to be on the other half of the panel than mine ) problem without solution.

1) On power up - display double images, and flicker once every few seconds.
2) After 3-4 minutes at this state - display suddenly back to perfectly normal (although there are few horizontal lines at the bottom of screen).
