Faulty lipo charger

My loyal lipo charger served me for more than 6 years and it was found that it fails to charge at 2A rate. Symptoms look like some sort of overheating as it fails after few minutes of charging repeatedly. The failure can be reproduced consistently.

Taking apart and no component looks fried. Likely a cheap way to repait is to change those capacitors that are close to the FET and coil that dried up the capacitors. After changing the closest 220uF 25V and 440uF 35V capacitors, it works perfectly as new. Then I change all capacitors prophylatically.
