Lawrence Hamilton start off by removing the back cover from your TV. Then take that interconnect wires off and make sure the contacts are clean, not corroded and not bend, Then reinsert them straight and ensure they are properly seated. That does include all LVDS cables. Since it comes on when you put pressure on the frame you probably will have to disassemble your TV and the panel. Remove the metal frame from the LCD panel like you would as you replace the LCD backlight strips. Check the connectors on the backlight strips as well as the wiring to it and the connections between those. You are bound to find something that is loose.
