    Best quote from Digital Electronics Repair: Troubleshooting and Fixing Devices

    “

    Professional technicians find that nearly 40 to 60 percent of PCB faults are actually visible to the naked eye if you know what to look for. It’s not always some mysterious 'brain death'; it’s often just a cracked trace or a tiny, bulging capacitor.
