red standby light will flash red but no picture
I have a Samsung UN55HU9000FXZA that won't turn on. The red standby light will flash red and rapid flash when remote is pressed, but no picture. When I disconnect the One Connect box, the TV screen shows a pic of an unplugged One Connect box, then once I plug the box back into the TV, the screen goes black again. Tried replacing the One Connect box and cable, no luck. I also popped off the back of the TV and checked all the caps and they all look great. I'm now at a loss....any help from anyone would be great.
