X Cube Ultramod isn't turning on.

[Gustavs]

Hey guys. So I had this X Cube ultramod for around 4-5 months. Bought it brand new. Everything was working perfectly, but then couple of days ago I turned it off and didn't use it for couple of days till today. So today I tried to turn on, but it didn't turn or react anyway. I put it on charge , after couple of hours took it off and still didn't turn on. Anyone can help me with this issue - How to solve it? Recently I had problems with the liquid, it dripped on screen, but nothing happened.
