Response from Jonathan: With issues like this, a cap kit is a great place to start. Please see our post on Installing A Cap Kit for more information. In this post, there is also a link to the What’s My Monitor page on Bob Roberts website that will help you identify which monitor you have so you can order the correct cap kit for it. Obviously installing a cap kit does require some soldering skills so if you’re not familiar with this you might order our Volume One DVD as it has a soldering tutorial video that you might find helpful. You can also purchase this video on our YouTube page if you would rather go that route. We also recommend checking out our post on Removing And Installing A Monitor Chassis as you will need to take the chassis out of the game to work on it.

Since you have a Space Invaders cabinet, we highly recommend checking out the Space Invaders page on brentradio.com for manuals and other tips for working on these cabinets. The monitor schematics can also be found here which may help you out.

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