screen backlit but no display after iddle

[stefunpf]

Hi,

My phone is acting weird :

when i power up my phone, it works fine, display, touch and backlight.

Then when the phone goes to iddle mode (or i switch the screen off, or i make a call and the proximity sensor switch it off), then i try to power the screen back on, everything is fine except that the display won't show anything. The backlight works, and I can use the touch to answer some call by swiping, or open a application. I have to reset de phone to get the display back to work.

In short, the display only work after booting the phone.

Anyone can help ?

Thank you.

It seems that you have experienced this before

Contact your Local support to get it inspected, you can also repair the phone with XC and test it: settings > about phone > diagnostics > test

Hi Uliwooly,  (Login is messed up, i can't use my first alias ...)

Thank you for your quick answer,

But this problem is on another phone (girlfriend one). and i already tried repairing with PC Companion.

I guess i'll have to change phone since we don't have any repair center in here.

But it is a strange problem, work perfectly fine on boot and then doesn't work after iddle ... there might be a power failure in there.

Thank you for you time.

Don't forget to run the diagnostics, btw, does the phone has a protective case, film, glass that might be covering or partially covering the proximity sensor?

Uliwooly,

I have run diagnostic app, everything seems fine, the proximity sensor vibrate when i hover my finger over it. 

I have removed all accessories and cleaned the screen in front of proximity sensor

Repair the phone with XC and report back.

Uliwooly, 

Is XC, PC Companion ? If so i repaired the phone via PC Companion, and it did not change the problem.

Still working on first boot, then doesn't work after iddle
