    Samsung LED only lights when mainboard disconnected ue48h6400aw

    Hiya,
    I have an LED TV that died - when plugged in the power light blinks 7 times and the screen is dark. I disconnected the mainboard and the TV lights up when plugged. If I leave the mainboard plugged in and remove either side of the tcon, screen lights up (with nothing on it).

    I replaced the tcon and the same is still true. Does this mean it's definitely the mainboard and I should order one? Is there a way I can test it to confirm?

    Thanks,
    Gil

    Under the t-con you can find 2 elongated strips, on these are various capacitors of which 1 can be defective which is easy to measure. Just measure whether there is a short circuit.

      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 TV HG46EB690QB No picture, only backlight when disconnected mainboard
      by Henke
      I came across a Samsung tv that does not seem to start up. When i plug it in nothing happens except that the red led turns on. But when i disconnect the mainboard, the backlight turns on and immediately turns back off when i connect the mb again.

      I have tried to disconnect one, none and both cable(s) from the Tcon to the screen but it makes no differens. The PSU seems to work, but when the mb is connected one of the 5V cycles high and low.

      Anyone with inputs?...
