Thanks for the info.

It seems TV firmware has been corrupted for some reason and causing the problem. Since TV shows logo that means sustain boards and display panel are working. I would recommend to update firmware by going to following LG link to download the firmware update file along with upgrade instructions file to proceed...

http://www.lg.com/us/support-product/lg-50PM4700

You would need a USB memory stick for it. If it doesn't fix the issue then I'm afraid you would need to replace main board of TV, main board is one where all video inputs are located. Please check with following supplier to get identical replacement main board if you are working on this TV yourself...
