N99i - can't set backlight - GSM-Forum

mia.ts · 12-24-2008, 01:35

Hi, i have china phone Evolve GX650TV (dual-SIM, the same as TV N99i). Tried to set some settings in engineering menu (*#3646633#) and after set Misc->Assert Testing, the phone was restarted and brightness is very low. In menu, Settings... LCD Backlight, i may set brightness value, but backlight is still low. When i power-on phone, then backlight is normal during 2sec, and then is low again. I was trying get battery out and wait some time, no success. Any solution? Thanks!

Problem solved!!!

type *#3646633# and go to Device -> PMIC 6318 -> LCM BL Settings

set every level (1 to 5) to frequency 200 and duty 20 for Level1, 40 for Level2, 60 for Level3, 80 for Level4 and 100 for Level5.
levels must be setted separately, it means set values for level1, OK, go to LCM BL Setings again, switch to level2, set values, OK.... and so on.

My phone is functional again, i'm so lucky :-)
