In daily life, from centenarians to three-year-old children, all like watching TV programs very much. Especially when cable TV enters people’s life, TV has become a hot product. To receive more programming, you need to install a cable TV set-top box, or an in-flight box, which connects the TV to a signal source so that people can watch hundreds of programs. Of course, using a cable box requires hacking it.
Cable TV set top box cracking method
1. Put the set-top box near the high-frequency head of one TV (hereinafter referred to as TV 1), so that it can watch normally, and then use a branch to branch out the signal from the output end to another TV. One drawback of this approach is that the other TV can only receive five channels near the channel that TV 1 receives.
2, with a non-gate circuit or 555 circuit to make an open multi-harmonic vibrator, its resonant frequency as long as it can cover the entire frequency band of cable TV. (It costs about 6 yuan to make.) Place the vibrator next to your set-top box. Let the box pick up the signals from the vibrator, then use a branch to branch out multiple TVS from the box’s output, so that all the TVS can pick up signals from all the channels.
3, with high frequency audion such as 9018 to do a high frequency transmission circuit, the use of radio frequency output to transmit again, as long as the small transmission power, so that the set-top box can be received. Or use a coaxial video line branch to access the input or output end, remove the outer shield line, only leave the middle line about 1 meter long, the line is wound around the set-top box. Let the leakage signal sense to the set-top box.
Cable box to crack the breakdown of the viewing method
1. Unable to search the program or incomplete search of the program: the cause of the failure is the indoor circuit fault. For simple troubleshooting method, please check whether the signal line connection between the set-top box and the wall panel is normal, and then carry out “restore factory Settings” operation on the set-top box to search the program again.
2. The message “Please insert smart card” or “Invalid smart card” is displayed. The reason for the fault is that no smart card is inserted or an unrecognized smart card is inserted. A simple way to remove the barrier is to insert the smart card properly and insert the chip with the downward arrow at the bottom of the slot. If the situation persists, call 96868 to report a disturbance.
3, after starting the set-top box only picture without sound: the reason for the fault is to check whether the cable between the set-top box and the TV is disconnected. Check whether the connection line is connected correctly by simple troubleshooting method, and switch to the corresponding video state after the TV is turned on.
4. Some and all programs prompt that the “program is not authorized” : The cause of failure: the smartcard is not authorized by the channel. The simple method of blocking is to call 96868 to confirm that the channel has been ordered and the fee is normal. If the channel has been ordered and the fee is normal, you can dial 96868 for secondary authorization or dial 96090 for online authorization as prompted.
5. After starting up, there is no video output screen of the set-top box, and the panel displays Good: the fault is caused by incorrect multichannel video input of the TV; The set-top box is not properly connected to the TV cable. The simple method of blocking is to select the TV video input line as the line where the set-top box is located; Please connect the connection wire correctly.
6, TV programs appear Mosaic or pause phenomenon: : The reason for the fault is that the cable TV signal level is too low or interfered with. The simple method of barrier removal is to check whether the attenuation of the transmission cable in the room is too large (informal wiring), whether the quality of the connected devices meets the requirements of cable TV, and whether the devices are connected correctly. Check whether the signal cable between the set-top box and the wall panel is properly connected.
Once we’ve cracked the cable box, we can start using it. In the process of use we also need to pay attention to some problems, for example, can not use ordinary hard disk for the set-top box optimization processing, because the strength of reading and writing is too large, it will cause great harm to the set-top box, the most serious may also lead to the set-top box damage oh. Warm reminder, do not use cable TV set-top box under high temperature, otherwise the crystal frequency inside the set-top box will occur scorching phenomenon Oh.
