Like some of you already have, I just wanted to join in and say "Thank You!!" especially to SixerfFixer for starting this thread and everyone else that has contributed. I was able to get my cinema 600 up and running again yesterday thanks to the awesome info here, so grateful. Wanted to also share what I did if it can help anyone else. I have a cinema 600 with the sub and surround 3's that I bought at the end of 2020 and mine went out in the same fashion that most others have described mid year 2023. The system had been nothing short of amazing up to that point with no issues and sound that would fill not only our basement but almost the whole house. So when the sound bar initially went down I was heartbroken! Life has been busy so my sound bar has been sitting idle since it stopped working with the intent to eventually fix it or try and get a replacement. I got serious about it this past week and went the route of repairing the original power supply. I liked the idea of keeping the original power supply if possible and not using an aftermarket one even though it sounds like you can certainly go that route with success if you choose to do so. After reading this thread from start to finish I felt confident that I could replace the cap's on the 5v side and that would almost definitely do the trick...and it did. I only replaced cap's C05 & C06 (220uf 16V) on the original power supply. After removing the glue from the connections I disconnected all the power hookups to the power supply and completely removed it from the sound bar. I'm a diy'er and fairly mechanically skilled. Never soldered before but after a couple google searches on the basics of soldering and how to remover soldered capacitors from a circuit board it really wasn't bad. Definitely takes a steady hand but if your careful and have patience many of you I bet could do it. From taking everything apart to putting it back together I probably spent 1 1/2 - 2 hours, and that was with some interruptions from kiddos. Again, thanks everyone for this awesome thread. Now we are having dance parties and movie nights again with proper theatre quality sound!!
