Loss of signal query
-
15-11-2020 1:36pm#1Hi guys
In the past few weeks I seemed to have lost signal in a number of channels on freesat. The channel 5 channels , channel 4 and BBCs come and go.
Oddly ITV is okay but ITV HD has no signal at all.
I have included a signal check from my humax box, other rooms in the house are affected too
Just wondering have you any advice as to what I should do.
From what I can see the satellite seems to be okay on the outside
Thanks

Dish seems fine to my novice eyes. Apart from green algae growing in it which I gave a wipe. Looked at lnb too . Oddly now the signal has gone now pretty much for all channels
Went rooting around in the attic , could see nothing astray.
Out of curiosity what is this wee box for?
Also have this booster thing

All aerial related, the bottom one is a distribution amp. The top one appears to be an aerial combiner or mastead amp. How many aerials on the roof?
Your signal issue is likely to be dish alignment or LNB related.0 -

I don't have any aerials on the roof outside now at all. The tv guy said it wasn't needed a few years back and took it down.
There is a small aerial in the attic that goes into that uhf of the blue amplifier. See pic below
There was also a huge disused five foot aerial just lying idle up there , I took it down today
There is a bronze cable running from the masthead amp across the attic towards the attic of my converted garage , not sure why i need the amp but i switched it off at the plug that was near it and the Saorview channels turned off so looks like it's needed.
One of the the white cables on the amp is only a few inches long and disused the other white cable seems to trail over to the plug.0 -

Confusing setup.
You say that contract aerial is directly connected to Wolsey distribution amp, have you followed the cable all the way from one to the other?
Where is the power socket for that Wolsey amp? Is it plugged into the socket you switched off?
That Labgear amp/power supply(?), can you post a pic of the rear, model no. etc.?
That bronze/brown cable, is it a power cable or co-ax cable? Looks like that old brown, cheap and nasty ‘low loss’ analogue co-ax cable from a generation ago.
The large disused aerial could be an old VHF TV aerial, VHF was switched off back in 2012. That Labgear unit, be it a power supply or masthead amp or VHF/UHF combiner was probably associated with that old install but shouldn't be affecting the existing basic setup.0 -

So I went up the attic again today and had a closer look .
God i hate it il there , roof is quite low and there is new insulation from a few years ago lying over a lot of the cables in making it a nightmare for working in...
Just doubled checked Yes the aerial cable goes directly into the wosley distribution amp, it's only about three feet long.
There is a black cable running from the wosley amp and it does indeed come together with the main power flex cable from the plug I switched off that time. As already mentioned the labgear power supply has a white cable running to this point aswell , so there is three cables coming together and there is blue tape wrapped around them at the end point which appears to be connectors/junction box
In other words there is a mains power cable plugged into a socket this cable runs over into blue tape where the wosley cable and the labgear cable are also taped to into connectors.
See pic of cables coming together into connectors

I didn't want to take this tape off incase it's dangerous or I'd mess something up. From what I could see as you can see from the photo below there is earth power and neutral from power cable.

Regarding The labgear amp power supply, the bronze cable i mentioned appears to be a coaxial cable, it runs into the power supply where it says AE.
I assume this is the old coaxial cable you mentioned for the old aerial?

So I guess there is no need for this labgear at all now?
The labgear unit is warm to touch. So there must be power coming into it from where it meets up with the wosley and mains power cable.
Regarding the satellite issue i have called a guy out , i may ask him to disconnect the labgear unit while he's at it if it's not needed anymore as I don't like the thought of something getting power if it's not needed and potentially a fire risk.0 -

Sometimes when I press into UTV HD or BBC one HD my LG tv shows a blank screen for about one second and says currently no signal searching for signal then it shows up, any idea why this happens?
I just tried it with BBv One HD now again and it showed up blank for a good 20 seconds then came on fine.
It only seems to happen with HD channel and the SD verison is okay so far.
See screenshot below
