2019 iPad 7 Wifi A2197 does not power up
My iPad A2197 fails to power up. Since having the CPU replaced (as suggested elsewhere) would cost more than buying another iPad, I've decided to have a go at repairing this myself and hopefully up my skill set at the same time. I figure it's better than chucking it straight in the bin.
With the aid of schematics and a component placement diagram, and using my probe, I've found that caps C8120-C8126, C8180 and C812F are shorting to ground. All caps are connected to PPVDD_S1_SOC. As it's unlikely that they've all failed, I'm wondering what could be causing this short.
Any suggestions as to what to do to further narrow down the problem? What additional information would you need me to provide? TIA!
