Hi there! Got a problem with my Helix LT. I turned it on and play for 20 mins, left it for a while turned on and when I got back to it, it stopped work. I can see a black screen and pedal indicators light. Tried to restart it. Same stuff. Checked my house power. It's ok, 220V. Few days ago made an update to 3.50. Everything was perfect. Tried to run test mode and factory reset -- nothing happens Any ideas, recommendations, etc?
