Intermittent error on three channels only

[Arthur494]

For the past two weeks I have been getting the intermittent error message "The receiver is not receiving a signal or the signal is too weak", only on channels 104 (Ch4), 122 (E4) and 125 (More4+1). All other channels are working fine.
I followed Freesat's advice to rescan and to replug the box. These did not solve the problem.
It's a 6 year old Humax Freesat G2 500 (HDR-1000S/1010S) with an older Sky dish.
Any help much appreciated

While tuned to the channels, what does the signal info screen say about the signal strength and quality ?

There is a number of possibilities

The Dish has moved slightly

You Have water in the coax cabling due to inadequate water protection at the lnb end

The lnb needs replacing.

All the channels you have problems with are horizontally polarised. The lnb skew may need adjustment.

I would imagine you will also have issues with the other channels on the same transponder

300 Film4

974 Channel 4

Many thanks. You are of course right - Channels 300 & 974 also out. I have called in a dishologist.

Well, that's a word I haven't heard before.

I'm an expert in a different branch of that field!

Ricebowlologist?

 

[Trev]

You've got an ology? You'll be a scientist soon

Ricebowlologist?

I was thinking more of dishology as in the appreciation of Helen George, Rachel Riley, Shelley Long...

 

[Trev]

Well, you would say that wouldn't you. Or am I thinking of the wrong Rice.

Thanks to grahamlthompson for his diagnosis. The dishologist visited us this morning, replaced the 13-year old dish and assembly, and everything is now working fine.
