In addition , there are some automatic start , automatic shutdown of the fault, release the power button to shut down the boot , as well as crash phenomenon , often have appeared here, too simple to talk about some examples .

 

    (1) T2688 automatically boot : a battery is automatically switched on , press the key to shut down a few seconds and automatically boot, disassemble , remove the power transistor, then the power test machine , silly, still open ! ! ! Had to move the power IC, power IC approach is to provoke the 4th to the plate line open. After processing power on and try again , OK, entirely correct.

 

    (2) V998 automatic shutdown : dropped, with a few days , automatic shutdown , forced to close down a little when you flip the phone to shut down a strong point . Suspect CPU Weld, plus post-weld failure remains , together with the temporary welding , OK, troubleshooting.

 

    ( 3 ) ten long T90 crashes : press the power button to search the network when it crashed , disassemble , find fonts and font shape this machine S600 is the same, the two rows of the foot, such IC, easily due to pressure caused weld, plus welding gun with the wind over the test machine , OK, troubleshooting ;

 

    (4) T191 slow start : press the power to see through the forty-five seconds after the lights , the entire boot process , almost two minutes or so, the software did, according to a fault , changed his character, does not work, plus welding power source and CPU, failure can not be ruled out, then listen 26M peers say is not caused from a demolished a good machine over, ha ha , everything is normal !

 

    ( 5 ) The Nokia 3310 phone to automatically shut down, crash : open board found that the motherboard is very new, not into the water , did not Shuaiguo signs , try swapping two R301 and R217 exclusion , test machine , the fault has ruled out.
