    Philips 58PUS8536/12 Backlight ok, no image

    Hello,
    the TV turns on fine, seems to be working, but shows no image outside of a thick white vertical line as it turns on that also disappears almost instantly, and then it's just backlight. I've tried unplugging either side, but still can't get an image. I suspect it's a panel issue, but thought i'd ask some smarter people to confirm. I haven't found any weird readings, but then again i'm just randomly poking around with a multimeter.

    Any information would be appreciated.

    This IC on the right hand side driver board gets quite hot, but i can't find any shorts there, or what the IC is. The markings are 211607 2531.

      Tv Philips 55PUS6031 no image, backlight ok
      by Raulnn
      good night! I have this TV, with quite poor build quality. It has a tcon integrated into the panel, a single flex from the tcon to the panel, and the 2 panel controller boards joined by glued flexes. There is no way to separate them.

      The symptom is that the image is not visible, but the backlight works. How to know if the problem is in the main or in the tcon-panel? I can't override zones.

      The board turns on, there is no image.
      Read more. When the power supply is connected, the front panel indicators light up briefly.
      When you press the power button, the button indicator lights up. The board works
      there is no image, there is no matrix initialization, there is no image on HDMI.
      When turned on, the fans do not spin, but when they warm up they start spinning.
      When you turn off the button, the fans spin up to full speed for a short...

      Hisense 40H4F no backlight but turns off after splash screen
      by frannyjunk
      So I have this Hisense tv where the backlight does not come on. But when it is turned on, when I shine a flashlight on the screen, I can clearly see the splash screen then it turns off. I looked at the mainboard and was expecting to see bulged capacitors, but they all look fine. I unplugged the backlight from the mainboard, and get the same symptoms (i.e. no backlight, dark splash screen then just a black screen). Is this just a backlight issues? Do Hisense tvs turn off by itself if the backlights are unplugged or are bad? Or is this a mainboard issue?

      TIA.
