I would like to disassemble a dvd player. Is it safe?

One important thing to note is that charge may be retained in capacitors for an hour or so after a mains-powered device is unplugged, and those capacitors may be charged to high voltages. If you''re disassembling a device that has been recently powered on, treat it as energised until you have verified that the capacitors have been safely discharged.

My 2nd monitor HP ZR22w doesn''t turn on after plugging it off

Sound like bad capacitor and it''s easy fix if you have the time and patience. Even if they don''t look like blown, replace them. Another way to find bad caps is to let the device run ro a while, unplug it while running and touch the capacitors on the top/not pins! And only one at the time without any other contact! The bad ones heat up.

measurement

There are many different ways to test capacitors. Using a capacitance meter, using a DMM and an analog meter. In general, is it safe to assume that a capacitor is considered functional if it''s capacitance measurement is +- 20% of it''s declared value without doing the ohm/voltage test? Are these test overkill after the capacitance value has been verified?
