Losing TNT1 and TNT2

[Hiffy166]

Hi 

On HD channels 410,411 and 413 sometimes - TNT1 and TNT2 break up and give 'there is a problem with you satelite signal'. I have checked the alignment of the satelite dish and replaced the LNB but no joy. All the other channels are A1OK. Signal strength and signal quality are both typically 80% sometimes down at 70% - this problem is independent of the signal strength and quality.

Sometimes the regular 868 and 869 channels are OK when the others fail - sometimes not.

Clearly main Q box reset a number of times and cables checked.

Main box has plenty of recording memory left.

Satelite dish is on the side of the house.

If you’re seeing a “no satellite signal” message check that the connections from the Sky dish going into the back of your Sky Q box are still finger tight. Otherwise it’s very likely a dish misalignment or possibly a failing LNB (on the arm of the dish) so check the troubleshooting on this link
https://www.sky.com/help/articles/sky-tv-no-satellite-signal-sky-q
It may then give you the opportunity to arrange an engineer to check the alignment of your dish. If it doesn’t you’ll need to contact Sky to book an engineer appointment.

If you are connected to a communal dish you need to liaise directly with your building management company / landlord who will have their approved engineers to contact.

It’s worth noting that:

▪️ a misalignment is not necessarily something that will be visible to the naked eye and could only affect one or two channels

▪️ a Sky Q box requires a periodic 'Keep alive' signal that is delivered via the satellite so if that isn’t received the box will close down until the satellite signal is restored.

hi @Hiffy166 

As you have posted in SKY Q perhaps we should advise  that SKY would replace an LNB & re-align if necessary - is there any specific reason you did it (or got someone to) ?

Was the dish & LNB checked with a wideband capable meter or if not what ?

You should be aware that SKY Q satellite info does not report the channel being watched but a fixed transponder set in an engineer's menu

Hi Daniel

Many thanks for your help – it’s really difficult - I have 2 devices to help me find the satellites (and a compass) - they are both screaming at me or full deflection for the alignment I have - suggesting I have the best signal I can get. I only get the message for these channels.

We have tried micro adjustments, but it makes no difference - it is only slightly different to the adjustment by the Sky engineer - using that position it is worse!

Checked out your link - we have checked all that stuff. The killer is that it is only the TNT channels 412 the Sky channel is fine!

My next step - change the box ES340D9 which looks like Sky Q just in case it is not behaving.

Thanks again.

Thanks -  I have changed the LNB and the alignment has been checked.

Made many adjustments  using satellite finders - still only trouble on TNT HD channels.

Lets hope changing the Sky Q box fixes it!

Sky will no doubt want to send an engineer to check and/or adjust the dish before dispatching a replacement box.
