Students work on LCD TV

Hi just a posting were are fixing a 50 inch LCD TV. We found that the back-light LED was open, the left side of the LED strip behind the LCD had a bad LED. we tested the diver board and it was okay at 380 volts. The student learned how to troubleshoot high voltage power supplies safely, yes I did get a shock. Even with years of experience I get it once in a while, the important thing is keep one hand in your pocket while probing around high voltage, it can save your life.
