i agree with most of  what everyone says----
1.read the service manual  --
2. do a hard reset if controls work --this can cure some odd issues--but also clears the memory.
3. if controls dont work--and LEDs dont light up , particularly in rows --- check to see if brittle ribbon wires are broken-- this could mean the  $200 new  membrane panels. but be thankful they exist at all.
4. if individual keys dont sound  you probably have to clean the key contacts---  a slow but important process--- and there are 61 of them. all it takes is alcohol and q tips

Something similar happened to mine. I replaced the batteries, trimmed back the ribbon wires so they responded, and did a hard reset which erased all the sounds and brought it back to it's basics. I then reloaded the sound banks from the Rhodes Chroma site. It has worked like a gem for 3 years now

Chances are your ribbon cables have gone (what lets all buttons and sliders communicate with the CPU).

You can fix (if you're handy), or purchase replacements for about $200 from a guy on this list who's name I eluding me at the moment (but I'm sure he'll chime in promptly). I recommend the replacements - they'll prolong the life of your Polaris greatly. 

If you want to try the fix let me know and I'll send you a link to a video on how to do it. Involves some basic soldering, etc.

Hi Everyone!


How are you doing?  I just joined this board in an effort to have my Chroma Polaris be something other than a heavy paperweight.

I'm trying to diagnose the problems that my Polaris is showing.

So far I have done the following:

~ Plugged it in and tried playing a few notes - there was sound with a few keys, but it only registered the same note each time and on different keys and constantly alternating keys.  Some of the slider controls affected the sound (Attack, release, and decay), but others were unresponsive.  

~ I then attempted to run diagnostics using the lower function and program select buttons.  However, I was unable to engage the lower function LED rendering a diagnostic scan impossible (at least from what I can understand).

~ When I turned the Polaris off and on again different sets of LED's were illuminated 

My question is: could this be symptomatic of a dead battery/erased memory requiring a new set of batteries and MIDI sysex dump, or something much more complicated?  

If anyone has any advise OR just wants to buy this broken synth from me to fix it themselves contact me.

Thanks,
Chris
