| A bogey, with no quality assurance of the LNB, switch (power divider) and cable. Once there is a short circuit inside, it will cause damage to the power supply that the satellite receiver feeds to the LNB. Second, avoid using radio frequency to find stars. Once the frequency deviation (modulated frequency deviation of the TV receiver or satellite receiver) or the power supply of the satellite receiver interferes, the TV receiver cannot receive the weak satellite signal, which leads to the failure of the satellite search. Three bogey ratings unencrypted unlock signal of the channel. If the encrypted signal is an unlocked channel, once it is searched, it will display "No available channel" at light, or it will cause a "dead" machine, memory disorder, or continuous search. Four bogey, receiving analog signals. There is no "symbol rate" data for analog signals. Therefore, searching when the "symbol rate" is "0" will also cause a "dead" machine. Five taboos, set all "PID" codes to "O". When all the "PID" codes are set to "O" and search, the standard "PID" code tracking circuit in the machine will be disabled, and it will also cause a "dead" machine. Six bogey, use the "CH" button to quickly change channels. When you use the "CH ±" key to quickly change channels, the computer inside the machine will not be able to "compute", which will result in a "dead" machine. Taboos before no new channels, delete all factory preset channels. When all the preset channels of the manufacturer are deleted, the program database in the machine will be blank, and the working procedures of the whole machine will be disordered, or the manufacturer must deal with it. Eight bogey, indiscriminate use of combination locks (for machines with combination locks). Locking the platform indiscriminately with a password, once forgotten, will cause trouble for your normal use. Nine bogey, and the TV receiving radio frequency signals together. When placed together with a TV that receives radio frequency signals, the electromagnetic radiation or modulated signal of the power supply in the satellite receiver will interfere with the viewing of the TV (that is, the screen will appear textured). Ten bogey, use in thunderstorm weather. Because the circuit structure of the digital satellite receiver is more complicated, it works in a state of low voltage and micro power consumption. The ability to withstand high voltages and large currents is relatively fragile and can be easily damaged by induced lightning. Especially for machines with no AC shutdown function (for example, Jiaxun DVB-3000), it is best to unplug the power plug during thunderstorms. |
