Ld = all water level lisghts flashing slowly accompanied by 5 fast beeps every 4 minutes - LID is open position

got this out of machine manual hope it helps

ld indicates a LONG DRAIN. yo ucan remove the lower panel and clean the filter housing, this will impede the draining abiltiy

replace the lid switch

I would guess you bought a dud micro drive or its been cleaned off. You could try a hard reset and see if it fixes itself. Perhaps the fellow cleaned off his information but hopefully he left the restore partition alone. You can rebuild that if you extract the files from the 2.0 upgrade and so on. There are a few tutorials on how and what to do on some of the hardcore LD sites.

Hopefully you didn't harm the board itself with a static discharge. I've seen a few guys do the swap and end up with a dead LD but usually they don't see anything at all.
