    today morning i switch the phone on, then its works!!!!!!!!!!!!!!!!!!!!!!!!!!!!

    what is wrong?

    sometimes working corretly, sometimes temperature warning….

    maybe the battery? or what component?

  7. newComer says:

    Imposssible to tell you what component(s) is causing the problem on a Liquid Ingress Damage Board Along without measuring. However, sounds like one of the cap or coil may suffer high resistance or shorts to the ground. If this the case, a can of freezer spray would do the trick. Otherwise, your fingers may also to be helped, touch across the board slowly while when it is on. Normally, you could able feel the area where is warmer than usual. Hope this to be helped…title=wink

    Its working 1 days Along without sim card.

    Today i put my sim, its worked correctly 2-3 hours, a call 8-9 numbers, i speak Along with my friend, and when i will put off the calling, the phone power off.
    I try power on, but nothing.
    I break 1 hour, and its power on, and now working correctly…

    (I tested, no warming components, board cleaned Along with isopropil alcohol.)

    Maybe the light sensor flex?
    Or the battery?

    The Jack flex (silent button, volume plus-minus) Its breaked, i glue it(now working), but its a different problem, right?

    look at the batt schematic , make jumper by pass the NTC and GAS_GAUGE thermistor tested 100 % by me
