I. Abnormal position locking module 1

The set-top box cannot detect the positioning module due to abnormal contact between the positioning module and the motherboard, or damage to the power board/positioning module/motherboard.

Solution: The earlier version of the set-top box, positioning module and motherboard were not integrated. Plug it in again to solve the "position locking module 1 abnormality" caused by poor contact.

2. Abnormal position locking module 2

Exception 2 in the location locking module indicates that signature verification failed. Simply put, the seed information is buried incorrectly or lost, and the positioning module does not match the motherboard.

Solution: "Abnormal Position Locking Module 2" appears on the TV screen played by HuHutong set-top box, so the user can't repair it by himself and needs to return it to the manufacturer or professional maintenance personnel.

3. Abnormal position locking module 3

One is that the user or seller mistakenly inserts the smart card of another set-top box into the set-top box; In another case, the card is not moving, and the work number holder operates to replace the smart card in the user management system of the household registration, which leads to the inconsistency between the set-top box and the existing smart card, resulting in "abnormal position locking module 3".

Solution: Let the seller or the work number holder who opens an account for this machine inquire whether the smart card bound to the set-top box matches the card number of the smart card actually inserted into the set-top box in the user management system, and then match the smart card.

Common problems and solutions of home communication set-top box

1) has no signal strength and quality.

Treatment method:

A. Check whether the signal line of the satellite antenna is connected correctly (don't connect the ground signal line to the satellite receiving tuner of the set-top box, otherwise it will damage the equipment) and whether the F head is tightened;

B. Whether the azimuth and elevation of outdoor satellite antenna are adjusted correctly,

C. Check whether the surface of the tuner and satellite dish are installed backwards (some cases were found on site).

D. If the above problems are confirmed, you can try to replace a set-top box device.

2) There is signal strength but no signal quality.

Treatment method:

A. The signal strength indicates that the outdoor tuner and the set-top box are well connected. Generally, set-top boxes can't find satellites. Please readjust the azimuth and elevation of the receiving antenna.

B. If it is confirmed that the outdoor satellite antenna is connected to the satellite and the signal line is correctly connected to the set-top box, try to replace a set-top box device.
