    Dell 23" monitor model ST2310f inverter fault

    Hi guys,
    I got in this set and i need some advice. There is an IC on a small upright board that solders into the power supply that drives the ballast transformer. The chip is marked AO3436 and has the shape of a rectangular 8 pin SMD I C. The chip is two mosfet transistors in one ic package. I get no info on this chip and neither a schematic online. I am not closeby to take photos because at that time i gave up trying to fix it. Does anybody in the forum know what i am talking about and can advise me on how to proceed. Its only a replacement chip that i need or maybe configure two n-channel mosfets to do the work.
    Regards

      Dell monitor PSU vs Dell laptop PSU
      by keepread
      Hi there!
      Someone gave me their old monitor, it's Dell S2715ht.
      The owner was using it when his PSU began to smell and then to smoke. It literally began to melt. He turned the monitor off, pulled the PSU, and ditched it because it was smelly even after it cooled. So I got the monitor but not the plug.
      Now, I tried to bring the monitor back to life, by plugging one of my many Dell laptop PSUs. They are of the same 19.5V, and the wattage of the laptop PSU is higher than that which the monitor is rated for. Visually, the socket on the monitor seems compatible, and the plug plugs...

      Guide to transplant MEC1503 EC chip and EEPROM reprogamming for T14s gen 2 and X13 gen 2
      by acedogblast
      This is a guide that I am writing for helping others to replace their MEC1503 EC chip if it breaks (or to get around an inconvenient prompt to the BIOS). This forum has been extremely helpful to me so I would like to contribute to help others. I will tell you right now that this task is very difficult to do. You MUST have experience and tools to do precision micro-soldering, BGA reballing, trace repair, and general laptop repair skills.

      There are some specialty tools needed to do this task. The replacement MEC1503 chips can be acquired from Aliexpress. Do not buy the bare chips as...

      Help with BIOS update on Dell G15 5515 after chip replacement
      by capoplays
      Hey everyone,

      I recently bought a Dell G15 5515 with an AMD Ryzen 7 5800H and 3060 RTX. The BIOS chip on it was dead, and my hardware guy replaced the chip. After that, everything was working fine.

      The BIOS is currently at version 1.22.1, and I wanted to update it. I downloaded the latest BIOS version from Dell Support using my ST: FQZMYJ3, but when I tried to run it, it says "unsupported system." I asked my tech guy what he did, and he said he took the chip from another board and flashed it onto mine.

      When I check the BIOS using the F12 menu Flash...

      ASRock B650M PRO RS - BIOS CHIP 25Q256JW BLOCKED BY STATUS REGISTERS
      by DynaxSC
      Hi

      I have a very strange issue with the BIOS SPI chip of an ASRock B650M PRO RS motherboard.
      The SPI chip is an Winbond 25Q256JWEQ model (1V8).
      The motherbaord doas not POST - it lits only CPU and DRAM EZ Debug Leds, and stays that way forever.
      The Flashback function of the motherbaord is also not working, despite all instructions followed correctly - I'm 100% sure of this.

      I have then desoldered the chip, backupped the contents, and tried to earease the chip in order to program stock image, but the chip is locked by status registers SREG2 (TB) and SREG6...
