@nishinoyay84986 could you repost an image for us? There are two things I noticed on here

and could be nothing. Probably just my old eyes but looks a bit odd to me.

@nishinoyay84986 did anything improve? I am so tempted to suggest the capacitors. They don't look to domed but some are always catching my eyes when I look at the images. Do you have a capacitance meter? Check your image, third one from the bottom. Around U10/U14 designator. Those 3 IC's are your OP_AMP. It looks like the solder on those "legs" has been worked on. I would at least try to resolder those. Here is [document|39212] datasheet for those. Check the Vin and Vout voltages and let us know what you get, after you resolder those IC's

@nishinoyay84986 U4 U10 and U14 are the amp IC's that I would definitely reflow. The whole area marked looks a bit unusual Even the solder on the capacitor looks dull and somehow wrong [image|3390858]

@nishinoyay84986 here is the schematic for the board in Question. Replace C72 with a 220µF 50V 20% Electrolytic SMD capacitor. Let us know what you get after that. Still, resolder U4 U10 U14 to make sure that those make proper connection.[document|39417]
