I woke up this morning and my Dell monitor was apparently dead. I noticed that the power button didn’t snap in and out like the others so I figured that the snappy thing must have broke and I immediately began the tear down and repair. Also, I forgot to show and mention that there are four black screws on the back of the monitor housing where the stand connects that must be removed before the housing can be lifted off. And please excuse my messy hair. After all, I had just awakened to a dead Dell monitor and had to immediately begin a rescue!!
