Help n900 screen goes black (blank) but working
 

Hello

I just have some problems with my n900. Basically the screen goes black after 10secs but the touchscreen is still working and I have to lock-unlock to use the phone.

How can I fix this?
Is it the battery?
or the phone?
or an app?
(phone went black...)
the phone is oc but I never flashed it yet in 3 years since I have it.

what about system settings / display?

Yep I'd say Display Settings.
Backlight timeout and Lock screen automatically.

i tried that but its go off too quickly like after 3 sec I type/touch the screen. I even installed that blank applet fron the app manager.

now its not working at all!

-when I turn on the led goes white, no vibration but the keyboard is lit
-the touchscreen is working as I can hear the touchscreen sound
-I tried change batteries and led goes yellow (error pattern)

please tell me what should do? open it and check the cables?

Open and check the cables or magnets. Screen settings does not sound too plausible anyway as blanking woulf also turn off the touch sensor. So you situation - touch working but screen not - suggests a hardware fault. Especially if it used to work but suddenly stopped.
