Diseqc help please

[fiestars]

Hi!
I have been using my f3 for ages now without any problems,
Until last night.
I have 2 dishes set up with a diseqc switch in place.
28.2 on port 1 and 19.2 on port 2.
It came up No Signal last night as I was watching something on 19.2,
So I left it a while thinking it would be the bad weather.
To cut a long story short,
Now only port 1 will work with either feed into it.
I have swapped them around and both feeds work fine, just only in port 1.
I have tried ports 3&4 but same result.
The settings in the f3 are unchanged.
Has my switch broken or is there any other things it might be?

Thanks

I have a similar setup to you (only I have 2 LNB's on 1 dish). I had to replace my DiSEqC switch a few months ago when the other ports started going intermittent. Sometimes I could get a signal & sometimes not. Changed the switch & all is now OK.

I take it that you also changed the settings in the Antenna setup menu to use ports 3 & 4 before phsically trying those ports on the switch?

I always keep a spare switch handy just in case of problems, as they are only a few ? on Ebay.

Do a final check on switch by removing one sat connection so only one dish in switch ports--if working then move to second port--if that ok then try second dish with same procedure [ensure port settings changed to requirements]
If both dishes work ok on their own then assume you need to buy a belated Xmas prezzie--a new switch.
