Guy at the counter said his TV has dust inside and asked me to blow it out
He came in with a 2019 Samsung, said it was flickering randomly. I opened it up and there was maybe a quarter inch of dust on the main board, but the real issue was a bad capacitor. Had to explain that compressed air wont fix electrical problems. Anyone else get customers who think electronics are just dusty toasters?

Blows my mind how people think dust causes capacitor failures.

Wow, really @adam414? Dust absolutely can be a problem in the right situations! I've seen it happen firsthand where a thick layer of dust traps heat and makes caps run way hotter than they should. Heat kills electrolytics faster than almost anything else, so if dust is blocking airflow around a power supply, it's definitely contributing to failures over time. Plus, some dust can be slightly conductive if it gets moist or has metal particles mixed in, which could cause tiny shorts or leakage paths. I'm not saying dust is the only reason caps die, but acting like it never matters seems like ignoring a pretty obvious factor.

Man thats a fair point about heat buildup, but I still see caps dying on clean boards way more often than dusty ones. Dust can make things run hotter, sure, but in most cases the cap was already on its way out.
