    Samsung UN40F6400 No Picture Bad T-Con or Panel!!!

    Dear all,
    I have Samsung TV, which reboots continuously and I opened the TV and checked for loose connection - disconnect and reconnect all cables.
    When I power ON and noticed that its entered into Burn mode (RED/GREEN/BLUE) screen and I turned off and checked the cables again but this time it turned into white screen only. No matter how many times I restart the TV the result is same. But Sound is OK.

    Needed your help and expert advise, whether it is the TCON faulty or Total Panel Failure??

    TV Model: UA40F6400
    T-Con Model: BN41-01939B

    Below are the Voltage measurement.

    TCON LED status: All 3 Blue LEDs are ON.
    Panel: 12.7v
    AVDD:17v
    HAVDD:8.5v
    Fuse:12.7v
    B1.8:1.7v
    B3.3:3.3v
    HVin:13v
    VonE:29.2v
    VoffE: -9.5v
    Vss: -7.5v

      What voltage do you have at the Panel_12V point?
      Willing to help but I'm no expert.

          TCL 50S535 bad tcon or panel issue?
          by x_orange90_x
          Just bought this for 10 bucks yesterday hoping to fix it. The guy said water dropped inside from a dehumidifier hose and it started showing black and white vertical bars then went blank. When I got it home and turned it on it came on fine and displayed correctly but I was noticing faint vertical bars in the image. After a little bit I turned it off and back on and it was a black screen again. I opened it up to check for water damage and corrosion but didn't find anything of the sort. I cleaned the ribbons anyway and reconnected them but still got a blank screen. If I disconnect the right side...

          Missing LCD Panel Voltages VGH, VGL, VCOM (TCL 55P6US Sound & Backlight but NO Picture)
          by maneatingmonkey
          I have a TCL 55P6US with sound and backlight but no picture. This model does not have a T-CON board, and the right (rear perspective) panel board is fed from the left panel board. I have not been able to induce any change by disconnecting the secondary panel board or the tape cut-off method on the primary board.

          There are a bunch of voltages missing on the panel boards. I can't find any shorted caps of the panel boards, and all of the missing voltage rails read in the kiloohms, which leads me to suspect the issue may lie on the circuit board, rather than a short in the panel.

          un60j620dafxza - Samsung No Display Problem
          by stylishconsultant
          Hi All,

          Need help.

          I have a samsung un60j620dafxza led tv. When I plug it in it has no display, no sounds, and no standby lights.

          So I opened the tv and disconnected the power to the mainboard and the backlight powered up. This according to many people says that this is a mainboard
          problem. I checked the voltage coming from the stb and I read 1.3 volts on pins 1,3,5 and 7 which are low volts instead of 13 volts which i think the lcd panel
          might be drawing too much power from the power supply that it prevents the right voltage going to the mainboard....

          Samsung UN65TU8000 - Panel Issue [ hole in ribbon cable ]
          by NWArkGuy
          Well, I will be the first to admit that I screwed up...

          In attempting to replace the backlight in a UN65TU8000, I made a hole through one of the ribbon cables between the board that runs along the bottom of the back of the TV and the panel. This lead to a between a 1/4 to 1/2 inch vertical stripe running the full height of the image.

          I don't have the experience; personally, to solder a bridging wire for the paths that were cut. So, I have been on the hunt for other Samsung TV's of similar size.

          I have 2 that I have found and have in my possession. ...
