@Suebur1 Is It a gen one TV you have? I recently got the Gen Two and have not had any issues with the lip sync since getting it. It is annoying, so I am with you there and agree it needs to be fixed asap.
Re: picture disappearing - a few of us have had this problem recently, where the screen goes black but the sound still plays. Sky Technical took me through a factory reset which solved the problem until the latest update dropped, when it started again. I did another factory reset and in the five days since it has not reoccurred.
It might be worth you speaking to Sky Technical and go through the same process? It's easy to do but as it can sometimes cause further problems they like to be on the phone with you to do it. A factory reset does mean you will need to re-set up your picture and sound settings etc. If connected via ethernet you'll also need to turn off your WiFi and putting Network Standby Overnight to on again is worth doing too to maintain connectivity.
