Punch-Out!! Sanyo 20-Z2AW flickering, horizontal bands and lines
The bottom monitor on my Punch-Out!! just started to develop this odd horizontal banding/lines that shows up periodically while you are playing the game. They flash on the screen for a spit second in seemingly random spots on the screen and across the width of the whole monitor. The monitor has been capped and has been very reliable thus far. If I unplug the video signal it still does the horizontal lines on the empty white no-signal screen. If I plug the bottom monitor signal into the top the picture is perfect. So, it's not the board.
Any ideas what I should be looking at? Is the flyback going? Can you get a flyback for a 20-Z2AW?
