I'm getting arcs across the exterior back of the tube!! HELP!!

Went to the thrift store and looked at a TV. everything was fine for the
first five seconds or so it was on, then I heard arcs goin' off like mad.
I opened up the back and they were shooting across the back of the tube
around where an orange wire was mounted to it with what looked like an EKG
pad(medical ref.) Judging from the power source (a bunch of undersized
and ratty extension cords) It could have been not grounded or experiencing
a line voltage issue. I immediately started looking for a capacitor but
I'm an installer of HVAC equipment by trade and troubleshooting is not my
area of expertise. If anyone has a simple answer please reply. It was an
NEC w/built in dolby stereo receiver (don't have the model #, didn't get
to look long). Thanks.
