Opening a mains supply is not a beginner's job. Mains voltage is inside, and the large capacitors hold a charge after the plug is pulled. Old mains capacitors can fail with smoke when first powered after years unused. Voltages can be checked at the output connector without opening the case, though a reading may need a load or other test gear to mean much. Board repairs mean soldering as well, with burns and flux fumes.
When an old machine shows nothing at all, the power supply is a common place to look, with dried capacitors and failed regulators as usual causes. Mark Fixes Stuff builds and calibrates a protector against a failed 5V supply before testing several unknown C64s. New Retro Repair chases a Saturn with no power. Some videos go further and reform old filter capacitors, as in the PET transformer job. Tony's Tinkering Shop opens a dead ATX unit, where the maker is sponsored.
