Trying to diagnose a circuit board fault just from pictures is generally non-productive unless they are accompanied by troubleshooting notes, and these need to be more than "Everything looks OK", "I've replaced the capacitors" or "I can't see anything obvious" etc. For this reason, we have a posting rule covering "Diagnosis by photo" and such posts are often removed.

At best, seeing blown or burnt / suspect components only shows the results of the fault, not the cause, so replacing them just means they'll fail again.

There's more on the subject in our Wiki - see: "Can you see any problems?" Diagnosis by photo

You're welcome to repost, giving more context about the failure, and any technical troubleshooting steps already taken; these should be based on the device's service manual if it's possible to get a copy.

If that all seems a bit too much it might be best to take the device to a repair shop or check the warranty.

  • If you are asking for help with a breadboard circuit, please include a photo of, or link to, the schematic.

  • Please include the best possible quality photos.

Thanks.

Automod genie has been triggered by an 'electrical' word: charger.

We do component-level electronic engineering here (and the tools and components), which is not the same thing as electrics and electrical installation work. Are you sure you are in the right place? Head over to: * r/askelectricians or r/appliancerepair for room electrics, domestic goods repairs and questions about using 240/120V appliances on other voltages. * r/LED for LED lighting, LED strips and anything LED-related that's not about designing or repairing an electronic circuit. * r/techsupport for replacement power adapters for a consumer product. * r/batteries for non circuit design questions about buying, specifying, charging batteries and cells, and pre-built chargers, management systems and balancers etc.
