Found this at the curb so I rescued it. This is the largest display I have worked on in a while. Tear down was nice and easy. 3 screws for the stand and three screws for the shell then pry at the bottom corners and wala.
Accessing the power board was also simple. Slide the main cover on one end to expose power lines. Unhook the remaining connectors and lift it up and three screws and the invertor board is free to work on.
Symptoms+Powers on with picture but flickering then black screen with blue power still lit. Turned it off and restarted it and picture came on without flickering but shuts down to black screen in 10 seconds or so blue power still lit.
Most of it is bulging caps as you can see in the pics. I think I will do a full recap knowing Samsung's track record with their tv's and displays. I was also pleasantly surprised to find so few caps on the board! Should be an easy fix.
