Hi. First post here. Total electronics beginner looking to learn how to repair all things electronics.
I heard that to test for a bad SMD capacitor, you should check for continuity to ground on both sides. It should only be grounded on one side, and if it's showing as grounded on both sides, there's a short somewhere on that line. Is that right?
So I have two identical tablets here. One with no power and one known-good. While testing the faulty one, I noticed a few capacitors on the main power rail (next to the battery connector) were beeping on both sides (black probe ground, red probe on each side one after the other)
Thing is, I took the known-good tablet to compare it with, and I'm getting continuity to ground on both sides of the same capacitors with that one too, but it works just fine. Am I completely missing something here or is the continuity test bs?
