Commodore 64

This is a template page for creating new pages for devices, troubleshooting them, part lists, and other repair info.

Causes
The voltage regulator on the 5V DC output fails routinely, producing a large voltage spike that fries the chips on the C64's mainboard.

Solutions

 * Only use a modern aftermarket power supply at all costs (the original power brick is virtually impossible to repair on account of Commodore filling the housing with epoxy)
 * If using an original power supply then an over-volt protector, such as a Commodore Saver from Ray Carlson, should be used.
 * A new power supply can be built with minimal effort using a small prebuilt 5VDC supply and a 9VAC transformer. Dave Farquhar has an easy guide on how to do this.
