From left to right I’ve noticed a series of lines roughly spaced 1cm apart across the entire screen. These are not consistent but more like moving pixels that look to be moving from the bottom of the screen to the top, they’re really faint however having noticed them its now something I can’t not see, any ideas? is this a sign of impending death?

I’m starting to think the T-CON board on the backside of the LCD panel has an issue. If you can find a panel which is cracked you should be able to salvage the T-CON board from it. The other option is getting a replacement panel. I’ve seen some listed on eBay for around $250 USD often I see them listed around $500 USD. Heres the part info: Apple LED Cinema Display 27" A1316 LCD Screen Panel LM270WQ1 (SD)(B1) - Apple P/N 661-5542
