The cause might be the Transistor, radio which is present in the circuit, A NPN or PNP transistor which supply the voltage and make it amplified.

Find out the faulty transistor, transistor are Three pin small mostly Black in color item, similar to the Capacitor And then replace it.
For checking you need to have the Multi-meter.

The following website are carrying useful info about transistor:

1. General instruction


Let me know if you are able to find out the fault in the circuit, othewise I will help you out with more useful information.

Make sure initially that cables are connected firmly and they are not defective. You may better try another connection cable. Make sure initially that cables are connected firmly and they are not defective. You may better try another connection cable.

If you want to try replacing capacitors, have a look at links below to get some usefull informations.
