Hello,

Could someone tell me which component of my TV has burned out?
The screen only lights up halfway.

Behind the left motherboard, at the power supply level, there is some burnt material between two solder points, but I don’t know which component has gone up in smoke. ????‍♂️

I have photos; is it possible to post them here?

Thanks for your help and happy new year!

    Hello
    there is a good chance that it’s the inverter (or backlight of the panel)
    what’s surprising is that it controls two parts of the screen, I thought a single inverter controlled the entire screen, but there may be two in your model depending on the size of the panel
    it's not too expensive as a part, I think it's worth repairing this time, unless the TV is really old

      I resoldered the board and it works great, but the neon lights are out.
      Do you know if it is possible to buy new neon lights? Or does that make the TV irreparable?

    It's behind the electric arrival that it burned out, but I don't know if there was a component that disappeared while burning out.

    re
    too technical for me; but if you know and have the right tools to test and repair, then go ahead

    Not sure given the photos, but some that are damaged need to be replaced.
    Best regards

      What exactly? It's the soldering at the power supply connection that burned out, but I don't know if there was a component or not.
