bradhig1 Posted May 8, 2018 Share Posted May 8, 2018 I opened up my Matel Football 2 and Funtroncis Red Light Green Light to see why the sound didn't work and in both games the wire and the solder meant to be connected to the center of the speaker has come loose. Can it be re soldered or do I have to tape the wires down? Quote Link to comment Share on other sites More sharing options...
spacecadet Posted May 8, 2018 Share Posted May 8, 2018 Anything can be resoldered that was soldered before... Do you have a soldering iron? Just stick the wire back down and heat it up. Good idea to use a little fresh solder on it too. Quote Link to comment Share on other sites More sharing options...
kevtris Posted May 9, 2018 Share Posted May 9, 2018 Those piezo discs had really rotten attachment, so it's a common problem for the wire to fall off. You can't solder it back on once it falls off, at least the point where it rips off. You can attempt to solder it to a new section that's silvered, but it will be really tough and it will probably fall off again. Fortunately those discs are replaceable with new ones that don't have this issue. Conductive epoxy might work pretty good vs. soldering, but I have not tried it. The problem is the disc is brass, with a ceramic crystal on it, and the top of said crystal is metalized, and the metalization is silver usually. It is poorly attached and it will just fall off real easy, especially at the age those things are now. Looks like they are all over ebay, in various sizes for cheap. Look for "piezo disc".

bradhig1 Posted May 10, 2018 Author Share Posted May 10, 2018 One of the circle things in the middle of one speaker fell off. Guess I will have to find new speakers. Quote Link to comment Share on other sites More sharing options...
bradhig1 Posted May 12, 2018 Author Share Posted May 12, 2018 Which size for the games? I see various sizes on ebay. Quote Link to comment Share on other sites More sharing options...
Keatah Posted May 12, 2018 Share Posted May 12, 2018 Measure the disc you have now. I've re-soldered many of these over the years, including ancient ones. It's a matter of prepping the surface right, then you get a great connection. Quote Link to comment Share on other sites More sharing options...
