Problem

This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector.

GPU is shorted and Imac wont boot at all. I informed customers that data are almost impossible to be retrived, and they are upset and think we are BS them. Of course being up in Canada, people like to believe that usa will have a better solution for it, a US data recovery company they searched on google told customer that they could get the data back without needing worry about T2 chip or Imac not working all that, I do not...

Hi, I'm an elevator technician. The attached oscilloscope display picture is from a digital elevator hall arrival lantern data signal. We have been having problems with “ghost signals” causing intermittent hall arrival lanterns to illuminate randomly when the elevator is not actually due to arrive at the floor.

The tech support of the hall arrival board manufacturer (CE Electronics) is blaming the elevator controller manufacturer (MCE), and the tech support of the elevator controller blames the hall arrival board manufacturer.

The boards are powered by a ground referenced...
