    Based on this pictures RT851 is for the DC OUTPUT jack, the RT852 is for the main AC.
    RT851 is the one that burnt up? If you do not use the DC OUTPUT JACK then you do not need to replace it, someone must have connected something into that DC jack and caused the damage to the RT851 and may be the circuit too.

      Wow!
      Thank you, Budm, for your quick response. I have taken pics of my board now.
      I am a novice and don't even know what these things are. But I am determined to learn to fix this stuff myself.
      The monitor exhibited the difficulty powering on symptoms. Also, someone had cut the power cord on the auxiliary speaker that gateway has. This jack is the 12v out to the speaker bar. I DO want to use the output jack

        At this point you should fix the main problem first and deal with DC output jack later.
        That part burnt up may be due to short circuit in the speaker bar.
        So carefully install the new set of caps first, bad cap may not show any sign of domed top.

          Thank you, I will do that.
          Hopefully, someone can identify that NTC Current limiter and I can get it and the cap next to it replaced.

            Macbook Air M2 A2681 Kernel panics after screen replacement
            by reformatt
            Just had a customer bring in a M2 MBA A2681 that had had a screen replacement in April at another repairer. Since then, she has been getting intermittent kernel panics. It's an aftermarket screen, and of course it fails in diagnostics as the calibration hasn't been done. The error in the panic log is "No device added after powering on the rails".

            It seems the original repairer has swapped the board and the screen to other MAC's, and said that it isn't a screen issue. From what I understand, by doing a quick search on Google, this is in fact a screen issue. The panic relates...

            Unknown transformer : how to find a good replacement part ?
            by the_rem
            Hello guys,

            I would like a quite old but still good 800 W ATX PSU to be repaired. The problem was an extremely heavy coil whine coming from the small secondary transfomer on the PCB.

            I desoldered it hoping the references on the upper side would allow me to find a adequate replacement part. Sadly the written references drove me nowhere but to the manufacturer (I-MAG). I sent them a message like a bottle in the see asking them to send me a datasheet of the transformer. And... They responded ! I received a kind of datasheet (see attachment) but my competencies do not allow...

            PS4 controller left stick potentiometer replacement issue
            by ezenia
            Hello,

            Not sure if this is the correct section, but I have a PS4 controller that I am trying to fix. It developed stick drift on the left stick and the usual simpler methods did not fix the problem.

            So I went on eBay and ordered some replacement potentiometers. https://www.ebay.co.uk/itm/174967976757 is where I got them from.

            I took the green potentiometers off the replacement sticks and soldered them onto the PCB. Assembled the controller and ran some tests. The drifting was somewhat fixed (not fully in center, but way better than before). However,...

            by boosti45
            i have a 2020 macbook pro 13" A2251 with 820-09149 logic board so i found an issue with chip labeled U6903 according to schem. boardview using flexBV software, so i removed it from the board and the issue im having is that the chip says "07A08FI ELC180​" on top of it but when searching for a replacement chip, i can find tons of identical looking chips that also have "ELC180" printed on them but the first set of digits is never the same so im trying to find out if i need this exact chip with these same numbers as mine and if not which ones are compatible as a replacement?...
