However, you should check across this capacitor - usually only one and by far the largest in the set - with a voltmeter and discharge as suggested in the section: Safe discharging of capacitors in TVs and video monitors if it holds more than a few volts (or wait longer) before touching anything.
Some of these are as large as 1,000 uF charged to 160 V - about 13 w-s or a similar amount of energy as that stored in an electronic flash. This is enough to be potentially lethal under the wrong circumstances.
If you want to be doubly sure, discharge this also. However, unless you are going to be removing the HV connector/flyback, it should not bother you.
The energy stored is about 1 w-s but if you touch it or come near to an exposed terminal, due to the high voltage, you will likely be handed ALL the energy and you WILL feel it. The danger is probably more in the collateral damage when you jump ripping flesh and smashing your head against the ceiling.
Some people calibrate their jump based on voltage - about 1 inch/V. :-).
There will be some HV on the back of the circuit board on the neck of the CRT but although you might receive a tingle but accidentally touching the focus or screen (G2) pins, it is not likely to be dangerous.
