Help Galaxy I9003- connecting to TV through USB

[Samsung fan]

I am using Samsung galaxy si9003. I am trying to connect it to my LED TV via USB through 'USB Mass storage' option. it gets connected i.e. i am to see the contents in the memory card on my tv screen, but after 4 to 5 seconds it gets disconnected. i think there is some problem in the phone which is preventing the connection for a extended time period.

Could someone help please?

thanks
