Redmi 3s LCD backlight not working
Hi, my Redmi 3s backlight is not working.
The phone can boot up and i can see the display IF i shine a flashlight on it
I disabked automatic brightness and placed it to full but the backlight still doesnt turn on.
How and where to test the backlight diode and coil?
thanks!
Is this a good question?

I have the same problem as well. Seems like a bad contact - it lights when I push the lower part of screen

Same problem here. It lights up when I push bottom of the screen somewhere between middle of the screen and right edge.
I disassembled the lower part of the phone - there's a little hole about 2x1cm (at the exact spot where I need to push the display to light it up) - there I can see part of the display electronics, but it doesn't seem to be anyway serviceable.
Does anybody know how to fix it without complete display replacement? Thanks.

Hi,
I fixed it putting small peace ( ~ 3mm x 15mm) of thick paper (cut a business card) into the hole you mentioned. You see the flat wire in the hole connecting display , so try to place a cut of paper between wire and metal part pushing it down to the bottom of phone and close to the right (if you see phone backwards) part of hole). Two+ months passed and fix is still working.

Wow, it seems that it helped, thanks man. It's only a few days, but the backlight didn't turn off a single time since then. Too bad I didn't try it earlier. I was so desperate, I already ordered Redmi 4 :)
