After myself graate because to the wireless mobile communication affection, grasped mobile communication tool the and so on the handset through training basic constitution, the principle of work, the breakdown has had the reason and the processing means, the breakdown question which proced to some market mainstream types had the certain understanding and the processing means through period of time social practices, I did the post-sale service work in the Harbin Great Wall correspondence company, the primary cognizance general breakdown examination and processing, the question which mainly faced in the service process is: Opening machine, does not enter the water, as a result of the external force to the machine harm and some software and hardware aspects questions, if in cannot open machine in the situation, first judges whether the battery does touch Fang Xujie, whether the power source triode does penetrate may use may adjust the power source to clamp the side contact motherboard to touch the piece cathode, does not have the response penetrates for the power source question or the triode, has the response but the power source indicator to return hits should or integrates the IC block for the motherboard leakage to have empty meets shuts the phenomenon, found the integrated block through the block diagram to be responsible for the power source a foot, The use low pressure iron takes the power source triode either carries on with the air gun to the integrated block has the goal the heat to sweep or found the empty contact through the microscope to perform to process, enters the water regarding the machine to be supposed to take the battery in the shortest time, the use processing fluid flushing, regarding automatic Guan Jixing the situation should consider the battery touches the piece and the soft association whether do get older, does not have the demonstration regarding the common LCD display monitor either lacks the character application to press the screen iron carries on processing or the replacement screen association to the screen and the motherboard contact point even advocates the screen, falls the line regarding the handset telephone conversation, the network inferior breakdown, inspires the electric circuit through the examination book to integrate nearby the block using the spectrometer the resistance to carry on the examination, The resistance number symbol prompt replacement, regarding software and hardware question and so on the CPU, memory, code piece, like does not appear phenomenon and so on additive device, passable computer software to procere and so on CPU, code piece rehas compiled, other questions must in the work the special details concrete analysis.热心网友 时间:2023-10-09 14:32
After I graated from the love of wireless mobile communication, through a mobile phone with training tools such as mobile communications basic composition, operating principles, and the reasons for the failure of the approach, through a period of social practice of some market failure arising from the mainstream models have a certain understanding of issues and approaches I Harbin Great Wall communications companies doing after-sale, primarily responsible for the general failure of detection and treatment, in the course of major maintenance problem is : do not switch on the machine, get flooded, e to machinery outside force damage and some software and hardware aspects, such as the fact that the plane of the first judge whether any side empty cells Next, Puncture power triode is the use of maximum power between parties may contact the Main Board with films being cathode, the reaction was no power or triode puncture, but a reaction to fight for power for the Main Board leakage or integrated IC blocks to open circuit phenomena are empty, find Jichengkuai through block diagram for the kick power, Use low voltage soldering iron down wind power triode or use a gun for the purpose of Jichengkuai heat up or through microscopes to find a way to deal with connections to machines get flooded batteries should be taken in the shortest possible time, the use of liquid water processing, automatic machines for sexual battery status should consider whether it is associated with aging film and soft, For common LCD monitors showed no missing words or pressure applied to the screen soldering iron screen with the Main Board point of contact for dealing with the replacement of screens or even the associated screen for the phone calls Diaoxian, poor network fault detection through the use of the spectrum -- circuit-to Jichengkuai near resistance testing, resistance value with the timely replacement of the CPU, memory, films such as software code, such as a mis-coding and other phenomena through computer software to the CPU, code rewriting proceres films, the work of other issues in a case by case analysis.
