hello,

I have an 820-00840-A motherboard, and there is no liquid damage. During my initial checks, I noticed that U3200 was getting hot, and I realized that there was a short circuit in the PP3V3_UPC_XB_LDO line. I replaced U3200, but then I noticed that PI3USB32224BXEAE was getting hot. I removed this component, and I haven't been able to replace it yet. Currently, the motherboard is drawing 5V at 0.021A, and then it goes back to 5V at 0.000A - 5V at 0.021A continuously. Is it happening because PI3USB32224BXEAE is missing, or is it due to a different issue?

"I replaced the CD3215C on it with CD3215B. Will there be any issues? Also, these chips don't have any firmware on them, right? Because I installed a brand new product I bought from AliExpress."
