I have Casiotone CT-360 keyboard. And when i'm
CT-360 was released in 1987, 20+ years ago. By now, putting the adapter in and pulling it out has vibrated its solder connections inside the unit. To repair, you will need a soldering iron, solder, and phillips screwdriver. Flip it upside down on a towel, remove all the large head screws and pull the bottom cover off. Looking inside where the plug is, you will see 3 larger terminal posts (lugs) coming thru the circuit board. These will need to be recoated in solder, one at a time. To make sure a better connection is made than the factory, carefully scratch the green coating around each just before soldering. This should last much longer than before. Be careful that no solder from splashes, or touches another lug. Test before placing the bottom cover back on. Recheck connections and resolder if needed. (Also, to stop battery corrosion, spray battery holder with WD-40 often). Happy playing!
