I also immediately had flash-backs to opening up an old CRT 13" TV that was going flaky (the sort of flaky where sometimes percussive maintenance worked). Being an electrical engineering student at the time, I thought I could handle it. I knew about the high voltage, I knew about the retained charged of the capacitors, etc, etc. What I wasn't prepared for was just how poorly shielded this thing was once I got it opened. I shocked myself almost immediately as I was doing basic examination. I hadn't even gotten to probing for shorts or broken connections. Thankfully, the shock wasn't bad, more startling than anything (I remember it being somewhat like brushing up against an electric fence). I was wearing a grounding strap on the arm of the hand where I got shocked. Not sure how much/if that helped any. That was enough for me to determine I wasn't qualified to work on it. I reattached the case and lived with its flakiness for a few years longer until it was replaced with an LCD.
