Thanks, as I had an to use tech support for my 930E when the Oreo update broke my ARC to only give me only 2.0 sound i am not willing to buy from non authorized dealers.Usually SONY does not service products bought outside heir list of authorized sellers. So yes SONY will not be servicing it in 99% of cases. Thing is that if you wanna take risk it is all up to you. Then even if something fails which possibility may be low but if it happens you will have to get it serviced from general electronic repair stores and pay for it. There will be no manufacturer warranty to start with. There can be warranty provided by store you are purchasing from but to claim that you will have to contact the store and not SONY. No one on this forum or any other forum will say doing that is fine. But the decision is yours and you have to take responsibility for what happens later and is on no one else.
