Jetson nano didn't get turned on (Even the indication LED itself not turning on)

Hi team,

My jetson nano didn’t turn on while using the 5 V USB power supply, even the indication LED itself not working .So with my own responsibility, i disconnected the SOM from the Carrier board, while visual inspection, i found some of the contact pin of SOM got rusted and corroded, and some of the components mounted on the SOM has a residual around the components, i have cleaned those residuals and corrosion using IPA solution, and additionally i have found a short across the some of the capacitors mounted on the SOM module, i have pointed out in the attached image for your reference, if possible can anyone explain what is the purpose of those caps and if it really a short which value capacitor should i try to make the jetson nano alive,

So kindly let me know If any suggestions to make the jetson nano alive

I don’t see that in your photo.

Is this a new unused module or a module worked well before?
