It can be done, but it is not a simple replacement. It is much easier to just add the Dish Home Protection Plan for a month and then have it replaced. They should ship you another 508 for 14.95 shipping. I have had to replace 2 508's over the years and never had a problem using the DHPP.
Actually it is Dishmod group.
might be better off upgrading to a 625 dual tuner box. it can output 2 seperate tv feeds at the same time
the one i took apart had a 40 gig maxtor in it. i saw it with my own eyes.
dont know what else to say.
how do i find ekb?
