There is a short somewhere. Check for any damaged whiring.
Start at the power cord and follow all whires. Put a piece of tape on the whires that have been checked and are good.
Check the isolation of the whires themselves as well as all connectors.
If any whire contact some metal, look if you can ensure that there is NO contact. Some string can come in handy to pull on some whires to prevent them from contacting damaging metal pieces.
Replace any damaged whires, or, if you can't replace it, use some electric tape to cover the damaged part.
