Usually this would be the ribbon cable going to the screen from one of the boards!

Check the connection first otherwise replace the cable.

Most likely failed capacitors in the power supply. I recently had the same problem with my 26 month old Samsung LN46A750. Samsung paid for the installation of an upgraded power supply board.

power supply probably went out

Samsung does not have any FW updates.

Hi, not sure if you have the same fault as i had, but our tv only had half the screen go off, after looking up on the internet i found a video for a fix, what you need to do is remove the back cover, there will be ribbons that go from the front screen to the main panel, i removed each one at a time and rubbed the contacts of the ribbon with a rubber on the end of a pencil, plugged them all back in and switched it on and it was now spot on, thats more than a year ago and its still working spot on, hope this helps jim

The tv power supply board have problems,like ingaging and dis ingaging inside of the tv,that the board where the power tv a/c cord plug into it.Tries websites lke Shopjimmy.com,Ebay.com to buy a whole refurbish tv power supply board for the replacement.

it still click on/off but now wont come on

It is beyond any reasonable repair---screen unit is called a display panel and the most expensive part in the set---cost of this would (just the part) be more than a brand new set.Let it go, some people do sell sets damaged like this on EBAY for parts.....
