I've seen like three other topics with this same problem... and now it's happened to me. All outputs (headphone and L/Mono) no longer have the right channel, which pretty much ruins the keyboard for me.

My warranty is most likely expired, so I guess I'll open it up- I noted somewhere else that someone just disconnected and reconnected some stuff and it worked fine again, but I have no prior experience with such things, so any help would be greatly appreciated.


Thanks!!!

Hi landon,

well, if you are going to open it, you surely know this thread:

Maybe there is a bad contact problem on the audio board. If you have no experience with opening electronic devices and you want to take the risk of doing yourself, here some hints that may help. But take advice: I will take no responsability for any kind of damage and injurys to anything.

• Remove all connections from your R3!!!
  
  Find a good place with plenty of space to do the work. Cover the surface with something soft like a towel, but take care not to use synthetic fibers or foams until they are marked as antistatic!
  
  Use the adecuate size of tools, to big or small screwdrivers could wear out the screws and make them hard to loose or to put again.
  
  Take notes about where the screws and parts come from and sepparate them if they are different (Use a cup or similar to hold them).
  
  Take care with static charges and discharges, they occur very often, every time you sit or leave your chair or move around. To avoid discharges into the internal electronic parts, touch first some external metal surface (covers, shields etc.) of the device.
  
  Locate the connectors on the audio board (see pictures of the link)
  
  To try to clean the contacts of the connectors, you can slide them in and out several times.
  
  Once done, assemble the device completly before testing it (You may omit the outer screws for convenience) Don't try to test it while the device is open unless you are an experienced user and are completly sure of having all parts connected and ther is no risk of short circuit.

Hope this helps. Please let us know if it worked!
