Why is my 2017 Honda Accord screen not working?

If Your monitor in Your 2017 Honda Accord is not getting any power then it's going to be wiring issue most likely. You should go ahead and replace the fuse that connects to it to see if that will fix it as that is the easieSTSolution to try. If the fuse being replaced does not fix the issue then next You're going to want to pull the screen out of it's hole and inspect the wires to make sure they are in good shape. If after checking the fuses and the wires You still cannot get power to Your screen then it is most likely the screen itself which has gone bad and will need to be replaced.
