Hello there. I have a Data East MNF. Today when it turned on there was a loud hum from inside, opening theme talking "Welcome to Monday Night Football...", was distorted and score display flickered various areas on and off. Although it completed start up checks and seems to play, obviously something wrong. I opened the bottom and other than speaker sound saw/smelled nothing amiss. I opened the top and under close inspection found some burning on a circuit board and saw some lights/sparks from behind the board. I believe this is a power board but am not sure. I have attached a pic of the noticeably burned board (inside yellow box). I am assuming I need to replace this part but wanted to run it by the experts first. Can you advise, please?

Rob, thank you so much for replying to my inquiry! C7 being the cylinder above and right of yellow box, correct? Instead of repair, new "drop-in" boards are apparently available, maybe cheaper than repair. Are these recommended, I would hate to ruin more than a power board!

Thank you again for taking your time to answer!

Rob, I just saw you are a board tech and I assume "circuit board".... Can I mail to board to you for repairs?

Thank you, sent!
