All the strings still there? Is the guitar still in tune?

If you suspect that a spring is loose, just remove the plastic cover on the back of the guitar that covers the tremolo cavity and see if a spring is loose. If it is, just re-attach it. It'll take some force and will be difficult without any kind of gadgets to help.
