TV HAS POWER TO IT BUT IT WILL NOT TURN ON VIA REMOTE OR MANUALLY
LG had a serious quality problem with the main board and there is a bad solder joint on all original 42lv4400 and 47lv4400 units.It will manifest the problem either went it gets warmed up and then power down itself or never power up. The red light stays on and the TV does not respond to manual or Remote input.
A factory reset will not fix this problem. It takes a "NEW" main board. The big white label on the back panel has the original manufacture date and LG will send out a factory authorized technician to repair the unit within the first year after that manufacture date.call 800 243 0000 to schedule a home visit to get the repair done.
By the Way, a 42lv4400 main board will not work in a 47lv440 even though they look identical. The reverse is also true.

SOURCE: LG TV - TV Guide Function Stuck
I have the same issue on an LG TV. The TV Guide is completely black with a small picture in the corner. It's as if the software is no longer working.
SOURCE: LG 26lx1d tv will not turn on. Power supply is
Have an LG26Lx1D for about 3 years, dropped off by my son.(Figures).Power light just blinking, but went back to red.Removed back panel, and metal cover. Just above antenna/cable input, its a small fan,mine was full of dirt. Blow off dirt, and make sure its turning freely.
Install back the covers, an voila....its a miracle...its working again.
Good luck
