Help... Hisense TV developed line


Active Member
My Hisense m7000 TV I purchased from John Lewis has just developed an horizontal line right across the screen. There seems to be a slight vertical line made up of green blue pixels on the same line as you can see from the pictures. Typically it's happened 3 weeks after warranty run out.

Does anyone know what is likely to cause this issue, would be cheap to repair ?
