i will try to heat them one by one with a soldering iron trying not to warm the other components around so i can be more sure if they are causing a problem or not.
even if you say that this not a the right way, the values of a bad capacitor changes quite a bit compared to an ok one so it can be used to check if it's bad or not,
and also measure with a capacitance meter. Try it and you will see that you can use this method to test.

I have enough repairing experience to know what works and what isn't. Just measuring capacitance will show capacitor failure only if it is completely dead. Also you need to desolder them out of the circuit before checking capacitance, otherwise measurements will be incorrect. I have enough experience to tell what likely may failed, and in this case, this does not sound like electrolytic capacitor failure at all. Also there is no prerequisites for them to fail in such usage conditions, even if capacitor quality is bottom of the barrel. If you read a lot of forum like badcaps and think that vast majority the failures are electrolytic capacitor related, the truth they are not at all. This is valid for some types of devices, but only for
some, not all. Also you claimed capacitors are crap, but did not say manufacturer or at least post a photo.
