    Samsung LNT4071 FX/XAA no picture with lines

    Hey all, gotta non working Samsung LNT4071 FX/XAA

    https://www.dropbox.com/s/222ccrm00z...707_154756.jpg

    This is what it looks like when the tv is turned on. The the discolored band down the center seems to be the menu, as it shifts after a few seconds from the left of the screen to the center. Here is a picture of what happens when you change channels:

    When you plug in a source you get sound, but as far as picture, you get this:

    First thought after some research was the TCON board. Ordered a new one off ebay that said it was pulled from a working tv with a cracked screen. Swapped it with no change. Then, I thought it was the FRC board, bought and swapped that as well with no change. So now I'm stuck. I've reseated the 4 TCON ribbon cables as well as the cables going to the FRC board and main board, also with no luck. It seemed like playing with the TCON ribbon cables made the lines come and go, but there is still no menu whatsoever. Does the TCON provide the menus? Before messing with it you could make out the small input display in the top left, but that seems to be gone now as well. Any help is greatly appreciated. Thanks!

      Looks like a bad panel to me, I have a couple of Samsung's that look like this and nothing can be done for em.

      If you flex the bezel does it change? Looks like the tab bonds to the glass from the TFT boards have failed.


      Also, try unplugging 2 of the 4 ribbon cables from the T-con to the TFT board up top and turn the panel on, does the unplugged side of the screen turn grey/black any change?

        Thank you for your reply. I was afraid of that being the case. Here are some pics of it with the right side ribbon cables unplugged:

        And the left:
