I'm trying to set up the DIY TinyTV kit and after assembling the TV I inserted the microSD card switched it on and got a message on the screen about needing to insert a card.

I had loaded additional .tsv videos onto the card before inserting it so assumed that I needed to install the Tiny Video Player Arduino Program which I did and now I'm seeing the error "Card not found"

I thought it might be an issue with the microSD card that came with the kit but after trying another card (which I copied a few .tsv files onto) I receiving the same error.

Is there away to reset it back to the way it was shipped? So that I can start again and try and figure out if the issue is with the card or if I haven't set up the board properly.
