I have a ball game show and I'm trying to fix the chaser lights. They work but are very dim. I reflowed solder on the light board connections.
Thoughts?

Quoted from pacmanretro:Pinphila, just saw this other thread. It's about totally out lights, but I quickly scanned over it and it looked like some others have already mentioned some great info of things to check voltages and where, connectors, caps, rectifiers, etc)
Hopefully it could help you too!

Thank you! I searched but couldn't locate any others. I'll report back
Update - 5v is coming in at j5 and j3. Onviously, the more bulbs I remove from the light board, the brighter they get. I will check the voltages at the light boards connection next.
Thanks guys. I checked the bridge and it's ok. I'll check the connectors again and reflow some solder
Well, lesson learned. Even though bridge checkout ok, it wasnt. Replaced the bridge rectifier on the chase board and all is well.
Just wanted to circle back and leave the results in case anyone else has the problem.
Quoted from pacmanretro:Super glad you figured it out!
Just curious...were you trying to measure the bridge "in circuit"? If so, how did it measure when you removed it vs. In circuit?
I did test it in circuit at first. I just trashed the old one however now I’m curious so I’ll pull that from trash and test
Quoted from pacmanretro:Cool. I was just curious if it could have been a bad solder joint on it (don't remember if you said you reflowed the solder on that component), or possibly was just reading different when in circuit. May be useful info for future people.
Thanks!
I did reflow the solder on the bridge but that didnt help it. Im 99% positive the bridge tested ok but maybe I missed something. Well, at least it works.
