Tune failed message keeps appearing.

[Martincape]

Hi guys,

I keep getting the tune failed message at least once a day, and it takes ages for it to come back on. It's like the satellite dish has fell off the wall, or the power to the lnb has been cut off.

Im using Apollo 88 and I can't understand why this is happening. Any suggestions?

 

[Martincape]

It's been off for ages now. Can't get it back on.

if you have a spare receiver or borrow one check that your lnb is ok this time of year with cold wet weather you can get water ingress in the cable if the boot seal has gone if the test shows the lnb to be ok then you need to look at your satellite xml file could be changes in some transponders that result in channels moving or could even be in some cases channels no longer available or not broadcasting at the time your checking.

Check your cabling and connections, most likely an issue with that.

 

[Martincape]

Cheers guys.

We have had some strong wind and storm weather recently. We don't have another receiver to check either. Is there a way to visually check the cables on the dish? Or if the lnb is knackered? I can only assume the cable ends in the house are sound.

Never assume, check the cables are physically ok, remove and refit the f-plugs is needed just to be sure. It is also possible that your dish has been knocked slightly out of line by the strong winds too.

I've had the box switched off all night. Switched it on now just to check. And it's fine.

SNR 94
AGC 82

How can I have an intermittent problem?

Until I had to personally set up my own dishes, I never realised how easy it is to lose a signal, even on a strong beam like 28.2 in the UK...... Setting up my 1.5M dish, I literally finger tap it to get it onto the best signal.... Too hard and you can be lose some channels even though you are still receiving on say 28.2.

So a strong windcan easily move your dish if not firmly fixed.

Unfortunately very easily if you have moisture getting into the connections..... Which with strong winds is quite viable if the connectors are not sealed with tape or covered.

 

[Martincape]

I'll have a look once it stops raining. Is it worthwhile, snipping an inch off the coax, reapplying the f connectors then taping up and reconnecting to lnb?

And it gets harder and harder to align the bigger the dish you use, I used to have a 3 meter dish in my garden (going back 20 years) and a few millimeters was all it took to knock that out of whack.

It certainly wont hurt to try.

maybe try some compression-f's, ive never been a fan of the screw on types.

 

[Martincape]

Never heard of them. I'll have a look.

 

[Martincape]

It's just gone again. Half hour before the match kicks off!!!

 

[Martincape]

Oops. Stupid tapa talk. Wrong thread lol

I have merged them for you.

I dont know what the weather is like for you but here in Durham it has gotten very windy in the last hour or so, so if your dish is misaligned or being battered by the wind it could account for your issue.

Exactly; the larger the dish, the smaller the angle.
A small (camping) dish is quite easy to align.

 

[Martincape]

Windy ish. But nothing major. Can't get outside to have a look either. Only me and my larl fella in the house.

 

[Martincape]

Try and figure this out.

I had a 3rd spare coax running in the room but not being used. Running from same lnb as the other 2. It was coiled up not being used. So I uncoiled it and plugged it in one of the tuners. Instantly got picture again. And both tuners are showing signal.

What's going on?
