I plugged in my TT One V2 into the mains elec to charge it. Suddenly on the left hand side of the screen (just under the connection) a series of coloured vertical stripes have appeared. The stripes remain there and I cannot even switch off. I tried to reset but nothing happened. I also tried to plug it into my TT Home but my computer no longer recognises it.
Is it dead? Please help.
