Leica Minilux Zoom - Error 51

[thecornflake]

So I took a long shot on a cheap broken Minilux Zoom for the hell of it on my favourite auction site (I knew it didn't have er01\02 but that it was broken in some way). Everything is ok except er51 and a few clicking sounds when the shutter fires. A quick search online sounds like it's a shutter replacement required but I'm wondering if it's worth taking it to bits in case it's something I can sort myself. I know this isn't anywhere as good as the fixed lens version but for the price figured it was worth a shot in case it was something simple.
