Gjpctech Posted April 5, 2017 Share Posted April 5, 2017 Has anyone run into an issue with the LCD display not working? It powers on, it's backlit, but I can't get anything to show up. I used the amp about 2 weeks ago, it was fine, turned it on today... nothing. Everything else seems to be working, knobs control the sound, drums work, selector knob changes pre-recorded tones, I just can't see what tones I've selected. I was going to try and flash the firmware, but I don't know if you need to follow prompts on the LCD display to even do that. Now that I look at it, the orange light around the "Drums" and "Guitar/MIC/AUX" button doesn't light up. Hope that isn't indicative of a main circuit board problem. Please let me know if anyone else has had an issue like this. Thanks! Quote Link to comment Share on other sites More sharing options...
daspazz1959 Posted April 12, 2017 Share Posted April 12, 2017 Im in the same boat. My Jam was having issues and I took it apart to clean it and check cables to see if they were loose. I found evidence that it had something leak into it from the display area. And there are/were rusted spots on the chassis and sa few spots on some of the boards. I did take it apart to clean it thoroughly. I got it clean but must have gotten some of the fluid behind the display, I could see a pool of fluid behind it. So now Im redoing the cleaning and focusing on the display its self. More later. Quote Link to comment Share on other sites More sharing options...
