dual tv problem

[upup]

I got the old dual tv decoder.
On some channels on the 2nd tv it says, interfere with Tv1, then cannot watch it.
How do I fix that.

You are probably using a splitter. You need a twin LNB. They cost around R299.

Got a twin lnb.

Try swopping the inputs around - the two that connect to the back of the decoder.

Also check your LNB alignment - did you move anything on the dish/LNB, as the slightest movement could also cause this (depending on the area you're in and other factors)

How long are the cables from the dual LNB to the decoder?

it use to work.
I see tv sig is 50%. Tv 1 100%

With the cables as they are, try 101 and 255 on TV1. Then swap around and do the same.

I reckon one of the LNB feeds is dodgy and not strong enough hence both tell are trying to get signal from one feed and they clash on certain channels.

Found the problem,
One of the feeds behind the decoder, when fastening it, the connector came a bit out and the inner did not make good contact.
Now all well again.
Thank you.
