why do you think theres bad connection to the display?the greyed out part on the second screen is the bar which is changing faster than the camera can catch up.the screen is fine as far as i can tell.but i cannot measure coltage with it,and it stays on at the off position,so there must be a problem with the dial terminals?(seems fine,not corroded or bent) or theres a blown component on the track somewhere but visibly theres no damaged part
