Basicly, you can try to inject 1v on power rail of cap and look if there is a draw, if u have draw, then look for hot spot and remove broken element. Just be sure to limit it with 1a
Long story short, sometimes I do buy broken handhelds and try to fix them. Last year I bought switch lite with weird issue- no signs of life, and 0.11a on vsys after failed picofly installation. I ve spent quite time on it, without any result...
btw i feel this a good time to remind you guys that sea of thieves was made by rare, who also made DKC1-3 and DK64, alongside banjo kazooie and conker's bad fur day
