Hewlett-Packard HP1300 printer with 110V voltage, wrongly inserted into the 220V socket as a result of the power supply board burned out, how to repair their own?

1) The power supply part of the overvoltage insurance, pressure-sensitive components in the rated voltage of about 15% over the rapid conduction of the high current generated by the front of the fast fuse tube melted, generally two levels of pressure-sensitive components, the middle of the filter circuit. Few other components are damaged.

2) Emergency repair can remove the bad pressure-sensitive components, if the filter is bad on the straight-through connection (usually not damaged), replaced with a new fuse of the same specification. Later you can make up for the same type of varistor, but never plug in the wrong power supply oh.

3) If there is still a problem, you can pass on a photo or local simple mapping wiring diagram.
