Hardware: Modification reader
Xsat 410 - Maestro 1000 2000 9000


Certain subscribers satellite Channel, at the time of the use of their new chart with a demodulator containing Xsat 410, see appearing the message "chart error".
Here a simple realization suggested by Worldsat to solve this problem.
To make ONLY if the case arises, all the readers are not concerned.

To cure this problem it is necessary to add a "strap" between the components C6 and C8 in accordance with the visible photograph below.

The strap connects 2 points to the mass which are too distant. This strap cannot disturb the other charts because it does not modify of anything the characteristics chart. This dysfunction appears only on certain readers, and that with the new Canal charts, never with the old ones.

Either you are capable to make a welding, or it is necessary to turn over the apparatus in Service After sale.

It is necessary to disconnect the demodulator, to dismount the lid and to weld a wire between the components C8 and C6.
