Dashboard completely out. No gauges or lights or sound. Radio and stuff work

Hello, did you ensure the battery is fully charged? A charging system, starting with the battery, that is not working properly will sometimes cause failures of electrical components. Hard to say; could also be a blown fuse or other circuit issue. Best to consult an expert near you; this is a link to some shops that can help!
