Found a bad capacitor on a 10 year old Samsung TV by just listening for the buzz
My neighbor was about to toss a 55 inch Samsung from 2014 because it wouldn't turn on, so I took the back off, heard a faint high pitched whine near the power supply, replaced three swollen capacitors for $3.50 total at a surplus store in Akron, and it fired right up has anyone else had luck tracking down issues by sound alone?
