Default Instrument Cluster Gone Crazy!!!

When ever I start my car the lines in my cluster all light up! But, when it idles for a few minutes some go away and come back. When I drive around everything like mph,trip,mpg,etc. are lit up! Now does anybody know what would cause this and I could do to fix it?


Thank you,
George :confused:
