Common problems with your PCB (Printed Circuit Board) or in layman’s term your Galaga board which runs the whole play of the game include the following: (Please identify the type of problem your machine has from the following options below in order to narrow down the problem:)
-
-
- I can hear the sights and sounds of the game, but I can’t see anything on the monitor….Skip to the monitor repair section.
- When I put my coin in the game; it won’t start when I push the start button. Go to The Fixing the Galaga Game Buttons Post.
- My game seems to work just fine but I can’t move my Galaga either to the left or right during play; its stuck moving in one direction– or I can’t move it at all…Go to the fixing the Galaga joystick Post.
- My Galaga machine won’t register coins or doesn’t give me credits ..Go to the Fixing the Galaga coin slot Post.
- I have a stand up game but my screen now flips upside down…Go to dip switch section.
- My Galaga picture is wavy, distorted, it won’t center, or is rolling across the screen. Go to the Fixing the Galaga Monitor Post.
- Everything works but I hear no Sounds…Go to the Fixing the Galaga Sound section.
- My monitor comes on. I can hear the hum and crackle of it warming up, but no game shows on my screen. Continue reading below.
- My screen is showing gibberish (numbers lines etc): Please continue reading below and also Goto Our Advanced PCB Repair page. Also check out the Eprom Page.

Under this senario it more than likely means the PCB isnt generating the “game” for the monitor to display much like disconecting the DVD player to the TV set. It’s not your monitor’s fault that no picture is getting to it. You will first want to rule out whether you have a bad power supply or a bad PCB board. The PCB’s are usually very reliable and unless wired wrong most often times will work for a long time so let’s lean towards having a bad power supply under this senerio.
First, Plug back in your game. If you have a 15amp power supply as explained in Fixing the Galaga Power Supply post, then Check to see if the LED light is on.
If not, more than likely you have a bad power supply and will need to order a new one. Since these are realitivley cheap it’s probably a good idea to just go ahead and replace it anyway now to make sure.
Once you have the new one, go to the replacing the Galaga power supply post in order to install it. If you still have the old style power supply as mentioned and defined in the power supply section then it’s probably best to replace or bypass this as well with the new switching 15 amp power supply in order to get you’re machine up and running again. Refer to the installing a new 15 amp power supply post when ready.
If you do have the old power supply you can also check the fuses that regualte the power. With game unplugged! Follow the fuse produre in the fuses section to do this, however if the fuses test good then you have a power supply problem best to just replace it.

- Everything’s on, but the screen is all scrambled with letters, lines, numbers etc. OK you have a board problem if this happens, but even more specific an Eprom or Rom problem in layman’s terms “a chip” problem, or a bad connection somewhere. At this point if you have this problem you can do one of two things, you can order a new working Galaga PCB board and refer to the Installing a new PCB post; or if you’re feeling adventurous then this maybe a simple fix if you’re willing to take your PCB board out of your game and refer to the Fixing Galaga Eproms Page section. Please note they’re also Galaga PCB board repair services out there like this one, which will repair your board and mail it back to you.

Things to rule out first: Make sure that the PCB is in fact connected correctly to the wiring harness, make sure that noting has fallen off or has become unconnected and that the harness is installed in the correct place. Please refer to the pinouts and dip switches post.
