Hello!
Spoiler: it works! All Solved! Get your screwdriver ready!
It was great to find you all guys. Not only because I did not feel alone about the poltergeist happening in my 55UJ7750 like ethernet cable messages, youtube videos freezing for seconds, lower and lower image quality, and the worse: some basic magic control functionalities stopped working (back button, play/pause), but because you helped me to solve all of them with the last “internal cable maintenance” option.
And I say remote control issues were the worst because I though the remote was the problem and a new remote is on its way (well, buying a backup remote maybe was not a bad idea, only if the light cable surgery gave the tv some more years of youth).
Well, after reading the whole topic and the shared ideas, I dared to follow the self technical service approach. Magically straightening up the internal cables worked! I did not dared to disconnect them, but tried to check that they we well connected, moving them a little (it seemed that they didn’t move at all, but who knows). I used compressed air on the ethernet connector, around the cable connectors and all around the internal area, from a safer distance, longer than the recommended one. Air was the only thing I had at home (no alcohol or connector cleaning products at home, so… please do not shout to me if air was not a really good idea).
Finally, it all worked and image, performance and even remote control works perfectly again. We were all surprised how even the image looks really crisp and vivid (video quality was getting worse day by day without us really noticing)… all issues are gone for now.
Thanks to all, and try it by yourself if you are having some or all of the shared issues.
Let’s hope that we do not need to go again through the same process in the future.
It really felt amazing saving us from spending on a new tv (yesterday I was the hero of the evening at home… yeeesss!)
Thanks thanks!!!!
