    LG 50PC5D - How to Disable AC Detect

    Hi I have a LG50PC5D
    The 4A Secondary side fuse was blowing, replaced 2 shorted MOSFET,s
    Replaced some of the cap's, don't think any were gone, but changed them anyway
    Now when plugging in the Red Light on the front comes on, PSU Clicks once and then shuts off.
    If the YSUS board is disconnected it continually cycles, clicking
    AC DETECT in cycles between 5V and 0V
    STBY pin is steady 5V
    I read a post from TOM66 about disabling the AC DETECT, the indication was that this was done by bypassing the optocouplers.
    Can anyone please provide more information on how to do this

    ThankYou
    Peter

      Lenovo C861 Ryzen 5 disable 4GB samsung onboard ram
      by brotank
      I quiet struggling with board lenovo c681 to disable 4gb samsung onboard ram because they're faulty, I followed the instruction on the schematic to disable them with resistor codes but still not detecting the ram on the slot.

      can someone disable onboard ram from my dumped bios, please 🙏

      I tried the other bios on this forum with disabled onboard ram, but no success

      my final try is to find someone that can help disable onboard ram in my dumped bios attached in this post.

      after that I officially give up 😂

      thanks for awesome jobs 😊...

      Acer A317-53 need help to disable faulty onboard ram
      by b-slayer
      Hello.
      I have an Acer Aspire A317-53 laptop with faulty onboard ram modules, after online searches, I have only found two options to get it working :
      - first one is to modify le bios to disable the onboard ram.
      - second one is to disable the onboard ram by desoldering some components on the mainboard.

      so after some hours google-ing, i have to give-up the modified bios option, main reason is I couldn't find anywhere a such modified Bios, alternate reason is that if windows update makes a bios update, the problem is always here...

      so i found that my motherboard...

      Alienware 13R3 bios mod request - to disable dedicated graphics (dgpu failure)
      by Mr.Ultimate
      Hi everyone, hope to get someone to help and modify bios rom for me.
      I need to disable dedicated nvidia graphics chip permanently.

      GPU chip had failed(cracked silicon DIE) and I can only use laptop without failing if I disable nvidia graphics in dev manager (but it still draws power from battery and generates thermal signature.

      Ideally if it was disabled from bios at preboot.

      I believe it is possible, because if I attatch external alienware graphics amplifier , laptop at boot will disable dedicated graphics #1 (failed one) and will only boot with AGA...

      Disable faulty soldered RAM on Acer A315-22
      by mat2k
      Hello, I've been googling for some pointers on this but couldn't find anything that applies to this board. I have an Acer A315-22 (board NB8607) with faulty RAM between 142 and 174mb. I just wanted to disable the onboard RAM altogether, but this one doesn't seem to have any memory down ID resistors or strap in order to disable it. I'm attaching the schematic I found, the boardview for it also seems to be available somewhere in this forum but I still don't have a use for it lol.
      How would I disable the RAM on this PC? Thanks for the help.
