First check the cables under the back cover. If you're still having an issue, contact the seller - sometimes they sell faulty items, and usually just replace it no
Absolutely. That's the biggest thing I learnt from this repair - I only ever buy the whole replacement LCD assembly. It's usually only a little bit extra, and will save you a lot of heart ache.
Hi yes I think I had this problem. From memory it was a loose ribbon cable in the back of the phone. I also had intermittent faults with my speaker and vibrate. I could not figure out why, and bought a better new phone!
The Z2 was put together quite differently - a lot less room inside than the Z1. The screen on the Z1 was clipped on around the outside. Fairly intuitive to remove it as long as you go slow and be cautious.
It's be a while since I wrote this, but from memory the Z2's display should detach via plugs near the hinge-end of the motherboard. I wouldn't expect that you'll need to take the motherboard out.
The silver strip at the bottom of the LCD also covers some cables related to the antenna (which goes around the outside edge of the display.
Just a thought - if you do take yours apart, take some pictures and make a guide on ifixit. The Z2 was really well built, and it is great to be able to keep them serviceable.
Hi mate, try opening it up and checking the battery connection. I've had this issue before, and resolved it by making sure the connection was good. Should resolve the issue.
