I have an LG 42LH30 that has power, but no sound or menus. The backlight works. Here is the weird part. If I am facing the TV and I put a very slight pressure on the very top right hand corner of the TV bezel (push straight back towards the wall) the TV menus will pop on and the tv works perfectly. I took the back off the TV and looked at everything and pushed on everything with a plastic rod to test for loose wires, etc and can find nothing loose. I am assuming a bad panel (or cold solder joint somewhere) but this in an uneducated guess. I can actually rig the TV to work by using strong tape to slightly pull back towards the wall on the upper right hand corner, but I feel that is dangerous. Any suggestions, ideas or comments would be very welcomed and appreciated. 
*note* There are no bad caps (visual inspection only) and no burn or scorched areas on any boards or elsewhere. All cables are tightly connected and every screw I could find has been tightened but made no difference.
