I received a DSO Shell kit as a gift for Christmas and I am having troubles testing it. After soldering a couple components and removing resistor R30, the board does not work. The LCD shows a white screen, and the MCU (U1) gets extremely hot and I can smell it burning up. LM1117 (U2) also gets very hot but not as hot as U1.
I was wondering if there could be an issue with the board or the MCU?

Re: LCD White Screen and MCU Heating Up
Did you test the main board before soldering? Was it working?

Yes, I tested before soldering and everything seemed to be working properly.jye1 wrote:Did you test the main board before soldering? Was it working?
