Quoted from chefjoez:My machine won't power up. Is it a fuse? I hate to call in a tech....
Do you have any electronics knowledge beyond replacing a fuse? A fuse blows for a reason, so you would need enough electronics knowledge to go beyond just replacing a fuse that would likely just blow again. Do you have a DMM or voltmeter and know how to use it?
If you can't answer yes to these questions, you are best off calling a tech.
