I had that happen when, in the set-up menu, 6x8 switch had been selected rather than 4x4. If a receiver is set for 6x8, it will send out DiSEqC switching commands that confuse a 3-LNB dish, whereas if it is set for 4x4, it uses the voltage and tone controls that your dish antenna needs.ncriley said:
I have been told that with some receivers, if you slecct 3 LNB rather than 5 LNB in the set-up menu, there will not even be a chouce between 4x4 and 6x8 switch, but YMMV.
