The problem is in the LCD controller board is overheated because the power supply unit is at the bottomof the TV and the heat rises upward to the vent on the top of the TV. You can verify that is hest problrm by running TV with the back removed and have a small fan blowing on the top secdtion of the TV where the LCD controller is. This how I fixed my scrambled picture after warm up (I added heat sinks to the IC on the LCD controller board) : http://s807.photobucket.com/albums/yy352/budm/LTV-32W3HD/
You can try it if the board was not badly damaged already by the heat. My has been running great for over a month now.
