hi ppl.my sister is using this phone.there is something wrong with the phone lcd.the backlight is there, but it doesn't produce any picture or image.the screen stays black all the time.the functions still work like camera etc but basically operating it in blind lah.you could hear the shutter sound but don't know what you are taking picture of.

she already changed the lcd once.but not long after that it happened again.it seems the lcd is not the main culprit.and sometimes the screen is ok and working but then black out again.warranty i'm not sure cos i think she bought it during her trip to beijing
any solutions guys?
