You can try this trick for the trip button as I had the same problem with an Insight that I bought for 500 dollars. It's a bit tedious but it did work for me. You need to press the trip button many many many times.....maybe like 1000 times. At some point, the pressing will clean the contact enough under the button and it will start cycling through the trip settings. When this happens you have to try and reset the maint light using the prescribed procedure. Again it did work for me. I had a sore finger after.
