MM, It is a glorious day, after hours of troubleshooting I finally found the issue with the flickering, i had to set the video resolution to 1080p at 50 Hertz (usually reserved for Europe). Typically in the US it is 60 hertz! It was a small thing in the end that dragged out for hours, but now the picture is stable and the sound is in perfect harmony :-) so happy to have had your creative problem solving approach , I would have never gotten it set up on my own really. You really saved the day.
the Apple Remote code I have pre installed on the Beosys3 allows me to shut off and turn on the new Apple TV 4k , but i cant navigate through the menu or do anything further with my Beo4, so i resort to using the Apple Remote for now. i suspect the PUC codes need to be updated along with the LG TV codes too, which Ill mail it halfway across the country to the service store - unless you or someone happens to know if I can obtain and install the latest codes myself by chance?
you have perfectly anticipated my next move ;-) and I am simply awaiting the center beolab 7.4 to arrive, to complete my 5.1 setup. Im slowly getting more familiar with the menus and settings so feeling great overall about what ive tested so far!
the last real issue that remains is integrating my beosound 3200. I also suspect it may be a cable i just got from Ebay. I confirm the V.option (2) and A.option (0) and turned it off for a while then on, but the beosound 32000 remains inoperable (as you explained already which is normal). My next step is trying another one.
Overall, this really seemed impossible for months and now its actually done and very much thanks to your kind guidance and taking the time! I cant thank you enough really, everyone (dealers, B&O, sellers etc) i spoke with directed me to a technican but your openness make all the difference
