Hey folks, just found this topic while Googling for PLM not working. I'm glad is in this forum, because I just bought an ISY-994izw that I'm trying to setup. I ordered a new 2413s from Amazon but decided to try to fix this one as a spare as these thing don't seem to last long. Having said that, I bought mine in 2011 so about six + years of daily use.
Anyway, I opened this puppy today and here's some pics of what this looks like, specially the caps in the middle of the board. Has anyone successfully re-caped one of these little gems ?
