Now it's time to get down and dirty.
Let's pop that box open.
First things first: unplug the power cord from your TiVo and wait
five minutes for it to discharge. Do not—I repeat, do
not—plug the TiVo back in until you are all
The TiVo, just like any desktop computer, has a pretty large power
supply mounted inside its case. No matter how long you leave the TiVo
unplugged, it can still hold a sizeable charge. Be careful to avoid
it as best you can, trying not to brush a stray elbow against it,
lest you find out just how far you can jump.
In addition to protecting yourself
from your TiVo's power supply, be very careful of
static electricity, which can destroy your TiVo's
internal parts. A good idea before you begin is to touch a large
grounded metal surface with your hands to dissipate any electricity
your body has built up. It's a very bad idea to open
your TiVo up on a carpet.
Depending on your TiVo's
lineage (see earlier
in this chapter for the four types of TiVo architectures),
it'll have a different number of screws on the back
to remove with your screwdriver. TiVos of type 1 have three Torx
screws on the back, type 2s have four Torx screws on the back that
are surrounded by the top of the TiVo's case, and
Tivos based on type 3 architecture also have four Torx screws. The
Sony SVR-3000 (the sole member of type 4) is a beast of a different
color: it has two Philips screws on the back, surrounded by silver
from the top of the case. Remove these screws and the two large-head
screws on each side of the
the screws are removed, you have to remove the lid; this sometimes
doesn't actually turn out to be as easy as it
sounds. The tried and true method is to place the TiVo on the floor
and to kneel down with your knees at the front of the TiVo. Place
your palms on the top-side edges of the TiVo, toward the middle of
the TiVo's cover, and push toward the back of the
TiVo. Start with a small push, but don't be
surprised if you have to use the force of your entire body to jar the
lid loose. If this method fails, you can try using a flathead
screwdriver or similar device between the top-front of the TiVo and
the lid. Eventually, you will jar the cover loose, and it will slide
back and then up. Remove the cover from the TiVo.
And you're in.
