If you live near a West Marine or any shop that sells fish finders, take the head and ask them to plug it in to their power supply for display models. If your unit comes on with no problems then it is most likely your battery or your connections. I've done this 4-5 times over the years at the West Marine in Point Loma--my problems have always been with the power supply either unseen corrosion in the pin connector from the battery or once a battery that wouldn't take a charge.
