Response from Jonathan: Jim,

We have a saying here at Arcade Repair Tips: ASAP (Always Start At Power). Start off this repair by making sure that the power supply is working properly. Use your multimeter and the manual (here’s a link to one if you don’t already have one: http://www.arcade-museum.com/manuals-videogames/C/Centipede.pdf) for the game to make sure that the correct voltage is getting to the board. Check out our post on Checking A Classic Power Supply for more information. Feel free to contact us again if you continue to have issues once you have confirmed that the power supply is working properly.

Hope that helps. Thank you for your question and good luck with your repair.
