Strange "tune failed" message

[danped]

Hi,

There's a short story and a long version here, I'll keep it brief - I have a Vu Duo and a Vu Solo 2. I have been able to set them up without an issue so I am confident I know what I am doing. However my vu duo has developed a problem, it is in a second room and was working fine until I disconnected the inputs from the satellite dish, connected them to another box and then put them back in my box.

Now I can no longer get BBC North West or BBC4 HD - I get a tune failed error, there are several channels with a similar problem and also there are other (like BBC1 HD) which work perfectly well.

I have tried a retune, I have checked the cables are in with no luck. Has anyone got any suggestions why this might be happening or what to try?

Thanks,
Dan

Have you rerun ABM?

It may be coincidence with swapping the cables but it has been very windy recently, many people have reported loosing a few channels this last week, just a couple of mm of movement can knock some channels off depending on how well it was aligned in the first place.

I am not using Auto Bouquet Maker, However I have done a full rescan of channels.

Thanks - I will check out the channel signal strengths, however as this is a long shot for starters and in the longer version of my story I have had this problem before I think this is unlikely.

Only reason i say is i have an octo lnb on my zone 2 dish, the first 3 connections have no problems, but from then on out to number 8, some of the 4-8 connections can get some frequency's that the others can't and vice versa, 2 of them can lock ABM, the other 3 can't or don't receive a full scan, but they can lock to transponders the other 2 can't, it is obviously an alignment issue that has arisen and i will need to sort it when the weather is better.

It started working the other day for 36 hours. However it has gone off again. SNR is 100% and AGC ~82% do you think this is symptomatic of a dodgy LNB or misaligned dish?

I had a very similar problem and it turned out to be the lnb going faulty. Changed lnb and all working again.

Thanks - That will be my next port of call. I'll report back to confirm if it solved it or not.

Hi,

I fitted a new LNB and voila, it worked. I guess a "broken" LNB doesn't behave in a way which is obvious it is broken. Some channels you see and some you don't and it occasionally works!
What I would be interested to know is if an LNB can have one broken cable connection but others work.

[duoduo]

Yes they can, I know this from experience. I had this issue a few months back changed the lnb and all good. So issue was with zero yet solo2 perfect.
