Members jazzbassist220 Posted July 5, 2006 Members Share Posted July 5, 2006 I hope there's someone here who can help me with this issue: I recently bought a second JX-10, a bargain. It looks fabulous inside and out, not a bit like a 20 year old synth. Now here is the problem: The display is dead; when turned on all leds start flashing and no sound comes out at all. Does anybody know what's going on? I'm a DIY kind of person and could try to fix the problem if I had the chance to find out what it is and have the parts to replace. My older JX-10 works but it is so beat up that it looks like a fossil. I'm thinking of getting the best parts of both synths and make one. Thanks for any help.

Members gilbertopb Posted July 5, 2006 Members Share Posted July 5, 2006 I would check the batery and the RAM contents. In this case, you must reload the memory from the cartridge. There are internal tests for the JX. See the site: The Super JX Zone Hope help someway. Link to comment Share on other sites More sharing options...
Members clusterchord Posted July 5, 2006 Members Share Posted July 5, 2006 hard to tell, but one posibility is your display aint completely dead, but it aint getting the juice - check the power supply, if it works up to spec. all rails. use the instrument n service manual, to see if there's anything not working right in that dept - if anythings dead or drawing too much current etc. new capacitors on power supply are always a good thing. then take it from there, trace the signal and see what aint working as its supposed to. as gibert said, checking battery is also a good idea. theres a service manual somewhere online.. i just dont know the url right now.

Sounds like a powersupply problem to me. Sometimes a short IC pull down the entire rail's voltage. Check the main volates on the PS first. Link to comment Share on other sites More sharing options...
