I was having the four-blinking-light issue too. According to the manual it’s a short-circuit problem. I’d had some juice spillage issues and guess some got into the power port. I used a combination of blowing into the port, setting it in front of a fan for a few hours, and finally using a hairdryer on it (all very comical and pathetically novice on my part). I was going to do the old trick of submerging it in rice overnight to get the moisture out, but luckily it fired right up for me after a few hours of me occasionally doing the three steps I listed above. Lesson learned: don’t let it get wet!
