Horizontal lines and now a black screen

My trusty old Nexus 5 has been showing horizontal white lines on the screen the past few weeks. Whenever this started to happen, it would detect taps in random areas on the screen or become unresponsive. Rebooting the phone would temporarily fix the problem. Last night the battery got entirely drained and now when I boot the phone, it only shows a black screen. The led at the bottom is flashing in white. Has anyone been able to fix this issue? I was thinking that maybe a LSD cable got loose, so it's fixable, but from what I've read it's likely that the LCD is broken?

I hope someone can shed some light on what the issue is and whether I can fix it or not.

Thanks in advance.
