Here we are in April 2024 and my 2 1/2 year old Cinema 600 has dies, I presume with the same problem. I ordered the power supply. What are the names and size tamper proof screws on the back? I want to put in regualr screws because obviously these things need to be tampered with! - Thanks 

I used the T15 & T9 Torx Screwdriver open my Bar48.

Thanks for posting this repair solution.  I purchased a replacement power supply board for my Bar 48 that won’t power up,  I wired it in and checked output voltages and polarity but the unit still won’t power up.  
 

I’m at a loss now, any recommendations on common other causes?  
 

My Bluetooth sub may be a candidate for converting to analog input (might as well get the most out of what’s left).

 

 

 

In my Bar48 case  if VDD and STB connect with +5V , It worked for a while and then lost power again.Can't power on again . so I study this post say you can disconnect STB no plug in +5V ,  keep it disconnect.  It work great! my Bar 48 can work again.

我有同樣的問題〜當bar-48通電時.Surround-3出現峰值噪聲〜我已經升級了bar-48最新固件，但是沒有用〜我嘗試重新插入Surround-3上的電源線可以恢復正常。
