2006 Honda Accord LX with a single disc CD radio with code 2AC2

I have a 2006 Honda Accord LX with a single disc CD radio with code 2AC2.

I have had pulled the radio out of the dash, and disassembled it down to the main PCB where I was able to get it to work again by reflowing the solder on the major mosfet components and main transistor components on the right hand side of the board. This worked for a few weeks but the radio is back to no sound and it makes a loud popping sound through all the speakers every once in a while.

I was wondering if you had any idea what typically fails internal to the radio to cause this popping sound and no audio but would be fixed by using a hot air pencil to reflow components. I have the ability to replace any components on the board but I mainly was wondering if you’d be willing to share with me what parts you’d recommend to replace and also what the part numbers are.

Also, if you had access to a schematic or any documentation that would help me to identify what the various components are on the radio PCB that would be extremely helpful as well.
