Another successful repair here. Strangely, my PLM (usb) has been going strong for many years (5+), but it was my EZIO device that failed. I had tossed it into the recycle pile when I came across this thread and learned that this device has the same base board as the PLM. I only replaced C7 and C13 (10uf originally) with 100uf 50V caps. I measured C7 at about 7uf after I took it out. Glad to have my sensor back (which was monitoring my alarm panel). I hope the repair job lasts a lot longer than the original.
