That doesn't sound like a power-related issue to me. Try cleaning the contacts on the cart.

best method of cleaning the contacts?

EDIT: This is what i'm getting.

Use a pencil eraser to clean the contacts. Your RGB cable is inserted correctly too yes?

[SuperBeatBoy]

Yeah only fits one way. Get the same sort of thing without the cart in it.

Resolved. Used my multi-voltage and upped it from 5v to 9v. Working perfectly now, so it was a power issue after all. Loving it. Getting my ass handed to me on Sam Show 3. So hard!
