It sounds like you possibly disturbed the fragile ribbon connectors by opening the lid and repairing the jacks. These ribbon connectors were an inherent design flaw of a great machine and were subject to cracking and breaking over time. Don't feel bad, not your fault. And don't let this turn you away from the Polaris becasue sonically it's an amazing instrument, and other than the ribbon connector problem, it's a very rugged and reliable machine. If you look through the archives of this forum, you will be able to correct the issue. If you need furhter assistance, you can email me ~~> greg.rudd@.... I might be able to walk you through the repair process.

Today the output jack broke and the headphone jack had been broken since I bought it so I decided to fix both problems. The repairs went fine and its cool that I can now use headphones BUT now 6-10 on the bank selector doesn't work :( couple this with the fact that half of the buttons on the left panel don't work and it leaves me with half the functionality that I used to have because I would modify existing patches that had functions on/off of the dead switches.
