Hi i have a Kilburn speaker purchased about a year ago and it stopped working there is no sound coming out it powers up connects to bluetooth everything i tried with the 3.5 mm cable and is the same no sound at all. When i switch the input sources from bluetooth to 3.5 mm it make a noise

. I took it apart an everything looks good nothin burned etc I’m not sure where is the ic I’m guessing is in the top right cornem with heatsink on it

I replaced this and nothing changed I attached a picture
