Blue column/flashing line down right hand side of screen

[Bexy89]

My MacBook Air has been working totally fine. Took it out to watch something on it the other day and it was still working fine, then all of a sudden on the right hand side of the screen, a column about 1-1.5 inches long of weird patterned colours appeared with a flashing line down the middle of it. The icons and date inside the column are also reversed and my mouse icon goes backwards when it goes inside the column. The MacBook wasn’t even being touched at the time and hadn’t been dropped or knocked in any way.

I tried a few things like restarting to try and get rid of it but it was still there. I applied some gentle pressure on the screen and eventually the colum turned from multicoloured to light blue. It’s not a block colour, I can still see my desktop picture but it’s just more pixelated and light blue. The line down the middle disappears when I put pressure on the screen but reappears when I’m not touching it.

I’m baffled to be honest as it’s never done this before and the MacBook itself was just sitting on its own working normally then this just happened. Is this going to cost me megabucks to repair?

That sounds like an LCD issue. This happens occasionally, but I have no idea how common they are on MacBooks. I think you will need to have the LCD replaced, which typically means the entire screen assembly. This could cost you a couple of hundred bucks. If you do it yourself, it may be quite a bit cheaper, as you can just swap the LCD and not the entire screen assembly. You can google how this is done, there are videos and images available.
