No dash lights or no power to ANY electrical devices is a common sign of a problem way back at the start of the power chain...the battery, battery pos and neg connections, battery earth point, or power supply lines from the battery.
Check that Battery terminals, particularly the earth are tight and clean, including where the negative lead is grounded.
If they are good, follow the positive (red) power supply line from the battery to any junction boxes, then to the starter, again checking for clean and tight. Broken, corroded or poor condition cables can also stop power supply.
Do those secondary checks with the battery negative cable disconnected to avoid any surprises.
A multimeter or test lamp can tell you a lot about how far power is reaching along the supply chain.
Edit: and don't forget the engine to body ground strap under the car, rear RHS of engine.
