    • Simpsons pcb vertical line

      I have a simpsons pcb I am working on. It was giving me a flashing white screen but I got it to a playable stat now. Only thing left for me to track down is this 1 vertical red (some time in game play it will be blue) line on the right. If the voltage is 4.5V or below it show up all the time. If its 5V it only show up sometime. Does anyone know where I can start looking. If it's a custom IC which 1 could it be so I can swap it out when a spare become available.

      I await your answer, oh great one
