The main board is a pain to remove on the mk1, but can be done without touching the display board. The main issue with the display board is that it's easy to plug the display connector in 1 row off on the connector, which blows (surface mount) fuses.

You could send it back to us for repair, but the cost of shipping (if you're not in the UK?) outweighs the cost of repair by quite a lot... though if you bought a sled from us (if we have some mk1 ones left - we may have a few in a "need repair" state, which is better than building your own from scratch!)

Out of interest, how come it doesn't have a sled?
