VR 730 Issue

[Cody_StPete]

I’ve got a Roland VR730 that I’ve have for about a year and a half now. Just recently I’ve been experiencing an issue where when it gets hot (I.e. when playing outdoors in Florida) some of my keys stop working. It’s quite odd because there’s a pattern to the keys that stop working, my lowest E then up the keyboard it goes C G# C E etc all the way to my high C. I’ve already had a contact strip go bad on it and because it starts working normally once it cools down I don’t think that is the issue. Any ideas as to what might be the cause would be appreciated. Thanks!
