    Ok, if the 7805 isn't getting power, check if the solder points in the power jack are good. Reflow if needed.



    Try testing all the components that are laid from the power jack to the regulator. If that fails, try soldering a wire directly from the power jack to the regulator. It might be that some traces on the PCB are damaged.
