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.
This one looks to be a more difficult to diagnose because most? of TCON seems integrated ( CSOT BGA on buffer baord) into the left panel edge board ( looking from rear of TV) There are 2 buffer boards for each 1/2 of the screen. Main connects to the left buffer board... -
Hello team,

I'm having a random issue with this otherwise nice double oven/air fryer. It sometimes does not respond to the controls. Sometimes only the upper control buttons work, sometimes they all work and sometimes none of them work. The power supply is good as the control board has a steady 5V and 3.3V. The pushbutton switches are all good as tested with multimeter. When the buttons are working, there is about 2.5V to the high side of the pushbutton. I'm assuming pressing a button grounds the input pin to the microprocessor. When the buttons are not working, there is about 0.3 volts on the high side....
