When encountering module errors, besides returning the product, what else can users do? In fact, not all module errors require returning the product. For example, module error 3 can be easily resolved, while module error 4 can sometimes be fixed without any manual intervention.

Cause Analysis:The set-top box and smart card are bound one-to-one. If the smart card number inserted into the set-top box does not match the smart card number recorded in the user management system, the error “Position Lock Module Error 3” will occur.

When this fault occurs, it can be divided into the following two situations:

One is when the user or seller mistakenly inserts a smart card from another set-top box into this set-top box;

The other situation is when the card has not been moved, but the worker holding the job number has replaced the smart card in the user management system, causing a mismatch between the set-top box and the existing smart card, resulting in “Position Lock Module Error 3”.

Solution:Ask the seller or the worker who opened the account for this machine to check in the user management system whether the smart card bound to this set-top box matches the actual smart card number inserted into the set-top box, and then match the corresponding smart card.
