My FE31M shut itself down while I was using it plugged to power source a couple of weeks ago. I tried turning it back on but it won't come on at all either on battery or power source, tried severally but no luck so I left it alone for 2 days and it came on afterwards. But it's now happened again and won't come on. I am so afraid if it comes n again and I carry on using it that it'll blow up one day.PLEASE ADVICE NEEDED
