Hi all, My Tivo is a series 2 Humax with DVDR, model DRT400, not upgraded or modified. It is frozen on the welcome powering up screen. I understand from searching the forum that it is probably a problem with the hard drive, though I purchased it new only a year and a half ago! Anyway, I guess I will have to repair/replace the hard drive, but does anyone have any detailed set of directions on how to do so? I am a little computer literate but know nothing about upgrading or fixing computers. I'm trying to save myself from having to get a new machine and from having to spend a lot sending it in for repairs. Please help! Thanks.
