    SIL9385 Replacement

    Hi,

    I have a main board with an hdmi chip that needs replaced.
    The chip is a Silicon Image SIL9385 and the package is a 100 pin tqfp.

    I have some of the low temp alloy that will desolder the pins but this chip has a ground pad underneath.

    Can someone recommend a way to remove and reinstall the new chip? I have a hot air station but no preheater for the underside of the board.

    Thanks,
    Mike

      If the chip has failed you can use hot air to remove. Getting it too hot doesn't matter.
      Once the old solder is removed you can use solder past for the centre pad and hot air to replace.

          maybe use a hair dryer on the underside of the board whilst heating it from the top with your air station i know it wont get as hot as a proper hot air station but any extra heat will help with removal.

              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...

              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...

              Asus laptop EC/SIO chip replacement
              by ebugs
              Asus Vivobook 15 (board X513ea R2.0) gone dead when user plugged an iPhone cable into the USB-C port during boot. Now there's no LED light, no power at all. I checked all MOSFETs and capacitors, no shorts found. The board only has 3.3V and 5V present, no other voltages.

              I injected 3.3V into the EC chip power rail (ITE IT5125VG 128), and it draws 80mA, while the 3.3V LDO chip RT8249C has a max output of 100mA. I checked the boardview and found there are only two chips on this 3.3V rail, EC and Realtek audio chip. So I think EC could be the problem.

              I found the EC chip...

              Common SPI bios chip programming Questions and Answers
              ----------------------------------------------------------

              Q: I have a bios request,i can`t post my backup as i can`t read from the chip.

              A: If you can`t read from it how do you expect to write to it ?.

              Q: Why is my bios chip unreadable ?.

              A: The programmer is faulty or has a worn or broken zif socket.

              The USB cable is frayed,connector pins worn or some other physical damage.

              Not enough amperage or voltage to power the programmer properly.

              Asus Chromebox CN62 - wrong chip put on BIOS reader
              by BMCappelletti
              Long story short:
              - dad converted Asus Chromebox CN62 into Windows compatible, with mrchromebox BIOS, years and years ago
              - gave the computer to his son a couple years later
              - son now decided to revert it to Chrome OS, to sell it as original (re-writing BIOS with the backup one created by his dad)
              - too lazy to remove the board from the case, thought a voltage regulator was the BIOS chip (you know... it has 8 legs)
              (seems like the story was not that short)

              He used alligator clips to read the chip. No luck reading it. Removed chip and placed on a SOC-8...
