Sky Q - loss of signal arrrrrrgh

philstanbridge · 27 Jan 2019 at 21:44

This is the second Sky Q box i've had with the same issue. It used to work fine up to just before christmas. There's no pattern to this which makes it very hard to diagnose. I've got a LG 4k tv, Xbox One S and Sony bluray player connected.

Usually, when you switch the tv on either via tv remote or via the sky remote there will be no signal received from Sky. The only guaranteed way I can get it to work is to pop the HMDI cable in and out of the Sky box.

There is no apparent pattern to this, and it is really frustrating. What's more when the Sky engineer appeared before we couldnt rectify the fault which is just typical, but he swapped the box anyway.

Has anyone got similar issues? Would love to solve this. I've done a little research and it would appear there are two revisions of SkyQ boxes, and maybe one has this potential fault with certain models of TV, but again I can't verify anything and also, why on earth was it working perfectly before.

Directly to the tv. Own dish yes. The engineer ran some diagnostics when he was here and everything passed fine, so it suggests the signal from the dish is working perfectly.

Nope, no commone circumstances like weather. However, I can sometimes get the Skyq to work if I switch the channel over to say, HDMI 2, or 3. Then back to SkyQ - it may or may not work. Basically I get a blank screen with no signal received otherwise.

LG OLED 55B6V - Z according to the sticker.

I've just tried swapping the HDMI input around and I've run into the same problem. So it's not related to an individual HDMI socket, or cable.

(its the hdmi hanshake not a dish/signal problem - the sky box thinks the tv is not there or vice-versa - re-plugging hdfmi causes it to re-acquaint)

did they do a firmware update on sky or your tv ? - near xmas

... would say this kind of problem is not uncommon ... had it on a pc connecting to a pan tv, and a humax box connecting to a sharp tv, often adopting a strict power on sequence fixes it, or re-plugging, flakey hdmi leads/connectors can contribute too

Yes I believe SkyQ had some sort of update. The interface changed anyway. It does suggest its the hdmi handshake thing you mention.

I'm looking to see if there is an update now. For what it's worth it looks like the problem is quite widespread. People are saying its effecting high end and particularly 4k tvs. But there doesn't seem to be any fix forthcoming.
