Mac book Pro colourful screen lines

my mac book started glitching a couple of months ago but over the past week there are lots of colour ful lines and a black out of the left side of the screen. I've been told that I need a new screen but i only bought my Mac book 3 years ago after my previous mac book did the same!

I'm really not happy to have to spend another 650€. Is there an alternative way to repair the laptop? At least record that this is happening too often, I look after my tech well.
