I have a virtual boy I am trying to repair. The console originally had a display issue which was remedied by soldering in replacement eye patch ribbon cables. Worked great and was played for maybe 30 minutes a couple times. After being brought home, it stopped working during a game and never turned back on. The console's small DC power board has a red light when turned on and the speakers make a quiet pop sound when the console is turned off. No other sounds come from the console and no light from the displays. I checked voltages on each of the cable connectors from the main board (although I don't know the correct voltages) and they all appear to be present. What could possibly be be the cause?
