The worker is preparing the delivery of cell phone jammer

Remember Oh, if the changes too bad call, oh this, if this machine still does not work, I do not think CPU is software, but the possibility is quite small, I have not come across it Oh, if we tried this method can top stickers Oh. also tell you that a MTK command: # 66 # to quickly resolve all short-circuit cell phone these days of continuous cell phone received a few short-circuit, are different brands, just start to feel depressed, and later discovered that fact, this problem is very simple, very easy to solve, the power transferred to 1.0V positive and negative correspond connected, you can see the cell phone leakage. The worker is preparing the delivery of cell phone jammer     .
Motorola V3 power on press the power button has no current response, the cell phone does not boot. Generally Q950.Q953 between disconnected or R953 open, then there are power IC Weld or keyboard interface, poor contact, specifically addressed as follows: C961 out to measure whether the 3.6V the BATTER battery voltage, the absence of J-BATT contact, check the battery interface is good and whether the disconnection between the J-BATT 1-foot power supply IC U900 features the R17 feet. Housing .6 V measured in the C931 at BP, if the focus check the battery switching circuit. The ventilated condition of the warehouse of    cell phone jammer     can ensure the good working status of    cell phone jammer     .
Trigger voltage in the boot of about 7 feet of the keyboard interface J-KEYBRD, with or without 3.6V, if not most of disconnection between the power IC C900 Weld or U900 J12 feet and keyboard interface J-KEYBRD, 7 feet, the requirements from the direct or The fly line. Check the keyboard interface J-KEYBRD The contact is good, that is, whether the Weld or break whether the break, check the keyboard interface J-KEY-by BRD 7 feet and the power button. Or replanting to replace the power supply IC U900 features. Motorola V3 power on press the power button is only the 5mA about current reaction, the cell phone does not boot focus on examination of 32.768KHz real-time clock circuit is normal, the specific maintenance is as follows. The equipment in the corner is the best one of manufacturing    cell phone jammer .
Replacement 32.768KHz crystal Y900 measured in C909 at the whether BTIBATT real-time clock backup battery replacement. Check the keyboard interface J-KEYBRD 45 feet with power, whether the disconnection between the IC U900 features or replanting to replace the power ICU900. whether the disconnection between the check the 32.768KHz crystals Y900 and power U900. Motorola V3 do not press the power button current, collection does not boot. Motorola V3 power on press the power button 20-30mA current response, the cell phone does not boot. Power press the power button about 20-40 current fixed at a certain location can not boot, the general cause for font or the font itself is damaged, you need to change or rewrite the software. The director answered the customer’s questions about the data on the drawing of      cell phone jammer .
Motorola V3 does not boot, power is about 50mA current can not boot press the power button, the General asked boost caused by the replacement L922.L921, if the boost is still not normal, it is necessary to check whether the R921 open so that the power to boot an instant hit bad power supply IC. Repair to ensure the normal R921 can replace the power supply IC power test machine. Motorola V3 power on press the power button current rise up to 80mA or so horde does not move, the cell phone does not boot. Motorola V3 hold down the power button the cell phone will not turn on, let go immediately shut down. Whether the boot of about 2.775V WADOG maintaining signal measured at the R900. Replace 32.768 crystal Y900 or replanting to replace the power supply IC U900 features. Replanting or replacing the CPU.     cell phone jammer     can gain the higher quality with the help of the new equipment.
