Hi, this sound like the same fault as i had, our tv only had half the screen go off also, the right side, 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
