Signal issues

[GK716]

Some of the channels on my sky have no signal, upon checking the signal the strength is 70 and quality is 90. According to the box the signal is good. Tried restarting the box a few times and this hasn't helped

”No signal” tends to be a message from your TV. A “no satellite signal” message relates to your Sky box. Take a look at the troubleshooting on the appropriate section of this link.

You may then need to contact Sky and arrange for an engineer to check the alignment of your dish. Be aware that if you’re on a communal dish system you’ll have to contact your landlord or building management company rather than Sky.

It is no satellite signal on the channels that don't work. I'm assuming there is something happened to the dish, I can't access it to check as it's a communal dish in a block with a management company. 
Given that there is some channels that work perfectly and some that don't it must be to do signal on either the horizontal or vertical band. 
I am a bit confused that the actual q box states the signal strength and quality are both good?

Hi @GK716
The signal strength on Q is only related to a test transponder and does not necessarily relate to the channel being viewed.  It is only a guide.

Perfect, looks like the horizontal or vertical band has an issue. Will arrange someone to attend the communal dish

No one else in the block of 6 seems to have an issue, I cycled the power to the equipment which solved the issue for a few hours but it happened again.

I have updated the software on the q box, rebooted it and left it off for 20 minutes which brought the channels back for a couple of minutes. 
Does this sound like an issue within the equipment itself?
