White vertical lines after removing glass

Hi Stefano,

The cable your torn is just a grounding cable, it’s part of the shielding sticker which goes over the 3 main flex cables. The white lines usually mean the screen is done for. you could try to unplug the screen and plug it back in but I don’t think it would fix the issue. You most likely applied just a tad bit more pressure on the wire you used to separate the glass from the screen or poked it with tweezers and the screen didn’t like it, these screens are about as fragile as a potato chip (crisp if you’re in the UK). Sorry to tell you but you need a new display.
