Hi

I bought a faulty Nintendo Switch and the guy who sold me it told me he didn´t open it (lies). If I plug the USB C tester I get 0.52A

Once I opened it I realized it had a reflow in the CPU and when I removed the shield I saw a lot of missing cap in the CPU. Checking for shorts I just find one in a cap near the MAX77812 chip but if I remove it I still get a "short" but if I plug the usb tester I get 0.15A. Maybe the chip is faulty? I think it is a power regulator

On the other hand, maybe even changing the MAX77812, the "reflow" had damaged the CPU, what do you think? I atach some pics. Thanks in advance

Do you think it would worth to replace the MAX77? Or should I remove first to see if the short gone

Still shorted. I have seen one of the cap in the tegra SoC is also shorted, maybe both are related. Is there any way to see diagrams of the board? I attach the pic of the cap shortes in the tegra SoC

Put the missing capacitors and try to reball the Tegra SoC

As much I could do a reflow also. I have a Quick 2008 hot air station but not a reballing station. I think maybe is a stupid question but is there any cheap reballing station to start?

Capacitors I think I read they are 0210 1uF

    i don't think nvidia wants to get in the x64 cpu market anyways
  • The Real Jdbye @ The Real Jdbye:
    you've seen how much intel is struggling getting into the gpu market
  • The Real Jdbye @ The Real Jdbye:
    and nvidia is already doing ARM
  • The Real Jdbye @ The Real Jdbye:
    i don't think they want to take more focus away from their gpus
  • Psionic Roshambo @ Psionic Roshambo:
    Yeah I think Nvidia s future lays in AI GPU acceleration stuff if they can get that going it's going to be super interesting in the long term

    AI assisted game creation might become a thing

    At least that's something I think would be pretty cool.

    Many TBs of assets and the programming of something like that is going to be tough but I think it's something we might see in 20 years maybe sooner
  • The Real Jdbye @ The Real Jdbye:
    @Psionic Roshambo AI assisted game creation is kinda already here, there was recently that AI that can turn any 2D image into a fully modeled 3D object, it's not perfect, but it's a starting point, beats starting from zero

  • The Real Jdbye @ The Real Jdbye:
    before that there was one to generate a fully modeled scene from a 2D image

  • The Real Jdbye @ The Real Jdbye:
    but most recently, there was one that actually generates a working unity scene with terrain and textures already set up that you can import right into unity, that's a huge time saver right there

  • The Real Jdbye @ The Real Jdbye:
    and using LLMs to generate NPC dialogue and even dynamically generated quests is something i'm sure is already happening

    will just take some time for games made using those things to be completed and released
