2019 32in Toshiba power connected won’t turn on

I have a Toshiba 32 inch HD ready TV, the red light is on when I switch it on it turns green but then goes red again. The screen remains black at all time. Is this a common and easy problem to fix or should I just replace it ? It’s in a spare rarely used room.
