Can I work inside my TV without killing myself?

I have a ten-year-old Sony TV that's on the fritz. It's a good enough second set that I'd like to save it if possible, but it's also big enough that it's going to be a pain to haul in to the shop for an estimate. If I decide to pop the case and dive inside for a quick sanity check, what do I need to do to avoid electrocuting myself in the process?

A couple of weeks ago the picture started rolling back up on itself -- and eventually disappearing -- a few minutes after the set was turned on. In its early stages the problem would clear up for a few minutes after a gentle thump on the side of the case, which makes me wonder if the problem is just something coming loose inside.
I'd like to try the same first-cut debug approach I'd use on a PC: opening the thing up and making sure all the wiring is connected and any PCBs/etc. are properly seated. (I have no intention of doing anything more than that.) But I know there are some fairly juicy capacitors in there that pose an electrocution hazard even if the set has been unplugged. Short of not opening the case at all, what can I do to minimize the risks of navigating the set's innards?
