The rev B has had the powersupply parts replaced once and it died again. I have most of the parts still and they will go with the unit. The end has craked off around where the power button is. I can send a picture if I need to. Still looks fine (it's on the front left side where it broke off).
The Rev A unit does not power up but has the far right green button on. Not sure what is exactly wrong with either of them.
I have gone to a HTPC (which is a lot more of a pain than the Roku ever was).
PM me a reasonable offer for one or both. I have the boxes (I think) and manuals, remotes.
