It is black when turned on and after it warms up some, shows a picture for a few minutes. Then it goes black again. I do not believe that it is the back lights at this time. My model number is un55fh6200f. Any ideas? Thank you
It is very well that your TV has an LED problem. Many of these come into the shop for this problem. It is very tedious and time consuming to replace the LEDs inside the panel (TV SCREEN). Do not attempt do this yourself or ask a novelist. I would contemplate a new TV. Save the thought that, “I should of replaced the TV to begin with”. Thanks for asking, Matt of Martins TV Repair.
