    Asus X555LD, main board don´t power on. Only produces periodic clicks.

    I everyone.
    I'm triying to repair the X555LD main board, but when I plug the power adaptor only produces a periodic sound, like "clicks". When it happens, all the voltage drops to zero and restarts the normal voltages again.

    I checked the adaptor voltaje and it's OK. The voltaje after the first mosfet is ok too.

    I measured the resistance of the coils and the electrolitic capacitors and it's ok.

    I need your help, I don't realice what can happen.

    Regards, and sorry for my English.

      Is it possible to upgrade from a Vestel 17MB97 main board to a 17MB110 Main board?
      by cheeky2
      I suppose the real question is whether the existing pinouts from ether a 17IPS71 psu are cross compatible with a 17IPS12 psu? If they are then the exchange of the main boards should have no issues providing the screen is compatible with both main boards. Obviously you can change the screen configurations easily enough (providing you have the correct files) for the main board. Why may you ask would I do this? Well a lot of the smart features are no longer working on a Hitachi 48HBT62U main board I wish to give it a new lease of life!
      Obviously the same LVDS connector for the screen connection...

      LG 55NANO77SRA TV – Menu scrolling by itself even after removing button board (Main Board EBU66792103)
      by ygorsan
      Hi everyone,




      I’m looking for help with a persistent issue on an LG TV model 55NANO77SRA, which uses the main board EBU66792103 (also used in LG UQ80 and NANO75/NANO80 series).







      🧩 Problem Summary:
      • The TV keeps scrolling through the menu or selecting items by itself.
      • I removed the physical button board (the entire panel with power and volume buttons) and also disconnected the flat cable (CN202) from the main board.
      • The remote control is not in use (batteries removed), and the TV still shows the same behavior.

      Help Needed: Samsung UE55MU8000 Dead - Possible Main Board Issue
      by Asraf Atb
      Hi everyone,

      Im looking for some advice regarding my Samsung UE55MU8000 TV with main board model BN94-11606C. The TV suddenly stopped turning on and now shows no signs of life at all not even the standby light at the bottom.

      Initially, I suspected an issue with the PSU, so I took it to a repair center. They tested it and confirmed that the PSU works perfectly, even on other TVs. Based on that, I started investigating the main board.

      I disconnected the main board from the PSU, and the backlight turned on, which seems to confirm the main board is the issue....

      Toshiba 37bv701b power supply main rails
      by semiRocket
      The set is not turning on, when buttons on the front are pressed the button press sound is coming from the speakers, but the set is not trying to turn on, consuming only couple of watts.

      I am troubleshooting a Vestel 17PW26-5 from the set. Not sure how it is supposed to turn on main supply, but with the main board disconnected not getting the main supply to turn on either.

      Standby supply is working, PFC is working (390V), but the main supply is dead. Checked the mosfets and driving transistors and found they are not shorted and showing a diode junction. The suspicious...
