I am working on a Samsung UN46D6003SFXZA LCD/LED TV which worked but the backlight LEDs were failing. I got it down to the LEDs which are all along the top and consist of two strips of 72 LEDs each.
When replacing the LED strips, I only disconnected the cable to the little Remote control sensing PC board in the lower right hand corner and the cables to the panel. Nothing else on the back was disconnected or any of the boards removed.
After replacing the LEDs and connecting all, the red light comes on when plugged in but the TV will not turn on using either the remote or manually.
I checked that the new LEDs where good at the LED connectors after I mounted them but did not check at the power supply connector to see if the cables where OK.
Since the TV worked when I started, I don't think that a circuit board has failed. So, I'm thinking that it is something I did or forgot to do is keeping the TV from turning on.
I would appreciate any suggestions.
Thanks
