Hi,
I recently purchased a cheap non working Avalon Mini 60GH/s, after opening it up and having a good fiddle, I found that a single miner (1 of 8 miners per module) on one of the modules (1 of 2) was fried and causing the PSU to trip out and shut down the miner.
I simply removed the 20 pin socket from that miner so it is no longer connected to the backpane and it now powers up fine and mines on 15 of the 16 miners at around 55 - 57GH/s on high clock (375MHz).
I'm not that familiar with Avalons and I am not sure if I have more problems with the miner and can't seem to find any documentation about it. I noticed that I always have a much larger number of discarded shares compared to accepted shares.
For example, this is a screen shot of the share details after a couple of minutes running to show you what I mean:

Does discarded mean bad shares or does it mean shares that were lower than the min difficulty I had set (64 in this case). After a few hours mining I had around 3000 accepted shares, but there was over 5000 discarded shares.
Is this something wrong, or just the normal workings of the miner?
Reply from someone that knows would be appreciated.
