Thanks members for the early responed, and my further finding for
member's questions is:
(1) The DVD player's input voltage is 240 V AC.
(2)When reverse the plug in the socket will reduce to 60 volts AC
leakage
(3) When I measure a cross with 1 K resistor the leakage voltage become
zero volt.
(4)When measure between the earth and the metal panel is 0.04 in ma
range but 137 in ua range. unknow why resultant is different. ?
(5) When measure between the earth and the power input ( two pin )
there isn't any ohm.
(6) It is not a Single shock
