it really strange but my k800i {R8BF003, CID 53} has gone crazy !!
in the standby mode the DISPLAY will start blinking, but at very very less brightness. its visible when the lights in the room are off. this bugs be cuz its draining the battery too quick .. grrrrrrrr DAMN ... pls any suggestions ???

PS : Tried removing all patches ... re-flashing main , fs but still no luck .
the phone was never dropped or had any sudden impact too.

Its may be LCD backlight problem. faulty backlight LED or LED driver DC-DC step up convertor problem.

I suspect, LED driver because fast battery draining. there is a Inductor in LED driver, It may be shorted.

Do these steps:

If you can find another LCD display, try to change and check it. if problem same, check inductor.


Don't keep your phone on, sometimes, it will kill LED driver (due high current sink) and phone may be useless.
