What happens is the BT Vision box first unscrambles the signals for all the subscribed channels. Then it transmits those signals to your television in the same manner how you receive them from your analog and digital stations. Therefore, if you get an error message from the BT box on your screen, it means that the problem is with the BT Vision box. In this case, it would be a good idea for you to try resetting the box first. In order to do that, you would need to disconnect the box from the wall socket for about five minutes and then connect it back. In case, this procedure does not cure the problem, you can perform a factory reset. For that, you would need to simultaneously push the OK button as well as the Down Volume button till the box gets completely rebooted. However, you may lose some of the personal settings like your favorite channel options while doing it. Now, if none of this works, the best thing would be to call BT and have their technician deal with this problem.
