I had the same thing happen to my 987 a few years ago. It was still under warranty so the good folks at humminbird sent me a new one. I had to send in the old one then they sent me the new one. Just sold my boat (got a pantera IV) and the SI was starting to fade on the left side again. (no warranty left )Sorry that I cant offer any better advice.I would contact the the folks at Humminbird, they are very helpful.Last edited by Dwayne on May 6th, 2012, 11:33 am, edited 1 time in total.Practice Angling CPRCatchPictureRelease2010 PIV 200SHO
