LT26i xperia S - no backlight

[raru_mobi]

Phone working fine. I can make and receive calls, texts, make photos, internet, etc, but no light into display and keys. I can see on display, but only into some angles, especially in sun . My phone has no guarantee, so i can't send it to sony service. I even updated the software, but no luck Can anyone of you give me the schematic or backlight solution? Thanks!

you will have to replace the LCD

I don't thnik so, because the display is fully working, except the light. It even have no scratch, no cracks, etc. And one more thing: the lights of the bottom keys are not working, too. That's why i'm saying the display is not dead

I am searching for a service guy who knows where are the light tracks. Thanks!

Please note that my phone is working good, but no display light, no transparent bar light, no notification light. I'm pretty sure that one diode/coil cause this problem. Please, Sony team answer to me! Thanks!

if this was my phone, I would re-open my phone and make sure all the ribbons are properly connected
