Cell phone jammer uses the stream line mass production

Power 6305 45 # to a capacitor (capacitance investigation) between the CPU, if this capacitor is broken there will be pressing power 400 mAh get right back to zero, or its capacitance resistors are to be replaced this capacitor is broken, I have repaired this type, it is recommended that you meet this situation Do not blindly change the CPU to check the power supply 6305 to the CPU's view, met this model you can try are generally can. CPU full power of black and white in MT6226BA restart a normal grid electricity maintenance 6226BA chip CPU full power black and white re-starting to find network writing software is invalid under the normal conditions of a grid electricity or grid electricity for the CPU OK. The self inspection of    cell phone jammer should be carried out to confirm whether there is any problem.
No service 'network of MT chip common problem check the launch, receive, CPU, power IC, antenna switch, amplifier, filter, launch the VCO, the IF has been engaged in, or may not, how do? Maintenance ideas ready installed refund customers, accustomed to press * # 06 #. do not look do not know, look on the bright spots, all 0000000, one is not a software problem? first regardless, FLASH remove the Internet to find a write down the information, the boot put the card a try, OK. later to a lot of MT chip machine, services and network, I'll take a look at the serial number, the normal, then check the motherboard, an abnormal write information, almost all repair following is a little maintenance MT service experience. The mutual inspection of    cell phone jammer     should also be performed.
First, do not check the circuit, generally fly a false line, view IF amplifier 900M-RX-TX signal is not playing. General amplifier problem, if no signal, another 26M. Master clock crystal in this frequency offset caused by the machine where it is easy to no signal for a 26M does not work, Furthermore CPU Weld, not a lot of bad times. the software is not the last IF it is discharged to the general IF not been generally regarded If you move, then the fake fly line did not signal, we must first change a teach you how to fix A1200 Department show that the key failure of the four functions on the touch screen, no electricity significantly, does not recognize the card, to repair 90 or more. Safe protection function can be realized for use of    cell phone jammer      intelligent system.
After a period of time to study and consult the MOTO maintenance department staff, has finally come to a repair method can be more than 90%: We think a good top. Cell phone four function keys on the touch screen failure, while no battery indicator, does not recognize SIM card, first you have the information to the version of the 1200 write 1200, 1200R can be written in 1200 and 1200E, 1200 and 1200E can not write or wrote after the 1200R's can not be restored to the original version, remember! This step is not, then the next step. and replanting SC29343VKP-CPU and font, this step more than 70% successful, but pay attention, do not tough to remove the CPU, the temperature is suitable, or IF it got under trouble, red screen, no signal. is on a CPU, the case of the OB part. a side note, when you write data, only write part of that replanting 29343CPU No, you have to replace a 29343CPU the same font. Safe protection function can be realized for use of    cell phone jammer intelligent system.
After the three steps you have the opportunity to repair. Example: a friend took a 1200R over, he said, is mounted to the superstructure do not know why this problem after I took over, the first to write a data, but not to remove the iron cover, replanting 29434CPU.OK (tin hard, be patient) MTK low power shutdown maintenance kill the repair process three kinds of reasons for this failure detection circuit of the CPU on battery power failure, failure of 95% is water caused a small portion of the board break and CPU is bad. maintenance: removed the R104 exclusion, universal table the Ohm file measured R104 exclusion side resistance, resistance to the replacement of the R104 exclusion OK, there is no resistance problem, remove the CPU, check the R104 exclusion whether the same CPU, the D6 # C6 # no break replanting the CPU, not to replace the CPU 100% OK. cell phone jammer uses the stream line mass production.
