The light keeps flashing but won’t turn on it just won’t off the other day and has not stopped flashing

greenyross I would start by replacing the battery. Use something like this video to work on it. While you have it apart, check the component on the power board for anything that might look different. Something like a missing, charred or burned component is of course worthy of further trouble shooting. Post some good image of your boards etc. with your QUIESTION so we can see what you see.
