Chassis Modification

Question: Gentlemen,

I have recently been contracted to repair the games in a small local arcade. I have been listening to the podcast religiously starting from the beginning. I even suffered through episodes 6 & 7! I’m up to 16 today. Great job, very helpful all around.

Please find the attached pictures. I have a Wells Gardner 25K7191 chassis that seems to have been modified. It doesn’t power on and I didn’t see any glow in the neck board however, I was outside in the sun and it might have been to dim to see. There are two “chicklets” on the solder side of the chassis board and two jumpered leads. I will get you locations this evening. Do these look ok to you? There is also a resistor on the solder side of the neck board. It all looks a bit suspicious to me. What do you think?

Response from Jonathan: First off, thank you for listening to the podcast (and “suffering through” episodes 6 & 7 😉 ). We are glad you have found them helpful. Yes, some of our early ones are pretty bad but I feel like we’ve hit our stride now so hopefully as you progress through the episodes you will notice a vast difference between our first ones and our most recent ones.

Also, sorry for the slow response. This month has been crazy due to our efforts to try and move a ton of stuff out of our storage building. Unfortunately we will not be putting out a podcast this month because of this but we should be back next month with a special episode filled with content from our upcoming appearance at the Southern Fried Gameroom Expo in Atlanta, GA. Again, we apologize for the delay.

As for your question, these caps actually don’t look too bad. Yes, the locations would be helpful for troubleshooting purposes but the caps themselves look to be in good condition. From your pictures, it looks like the solder is getting pretty old. Michael, whom you’ve probably seen in our posts on monitor repair, always recommends refreshing the solder on any and all points that look cold on your monitor chassis anytime you have an issue such as this. I cannot tell you how many times we have “repaired” a monitor just by touching up solder points without replacing any parts at all. This would definitely be the first step we would recommend to you. A lot of times we recommend a cap kit not because the caps are necessarily bad but because it forces you to touch up the solder on these joints which could be where the issue resides. So, try touching up the solder and see if it makes a difference. Also, be sure to keep us updated on your progress throughout your journey to repair this monitor.

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