electronic dashboard went out, why?

Ours did the same thing, only the speedo lit up. It was intermittent before it went out altogether. It was not a fuse, it was the dash. On ours, it was the power supply printed circuit board (PCB). You'll have to remove the dash to fix it. Disconnect the battery before you pull things apart to prevent accidental damage. Maybe you can find a good used one, or there are places that will repair it for you. Expect to pay about $150 plus shipping. I was able to fix ours by removing the power supply PCB and resoldering the connections on it. This isn't something you should try unless you are very good at soldering and know proper procedures to prevent damage from static discharge, etc. You can probably get someone who repairs radios or TV's to do it. The power supply PCB is mounted pig-a-back on the rear circuit board of the dash assembly. There's three boards: 1. The front one, with the displays on it. Ours is green. 2. The rear one, under a metal plate. Ours is blue. This is the one with the power supply PCB mounted on it. 3. The power supply PCB. It's smaller, about 1.5 inches by 2.5 inches. You have to remove it from the bigger blue PCB to get to the connections on the back of it. This is the one where our problem was. While it's apart, have the tech look for other problems. There is a capacitor on the power supply PCB that should be checked and replaced if necessary. Once again, this is very technical work, work carefully. Good luck!
