I got toothpaste in my headphone jack (road warrior woes) I cleaned it out with a syringe and distilled water then rubbing alcohol. But now the device thinks there are headphones plugged in. I have no headphones plugged in, however the volume display says ‘Headphones’ when I use the volume buttons. Anyone taken apart a headphone jack on one of these that can tell me how it senses the presence of headphones? Contact switch?
Ok it seems fixed now. After cleaning the bulk of toothpaste out with a pick, and irrigating it with distilled water and 91% isopropyl alcohol in a syringe, it still smelled a ‘minty fresh’. So I boiled some distilled water, filled the syringe, and irrigated the headphone jack with hot distilled water until I couldn’t smell toothpaste in there. The iPad still thought that I had headphones plugged in, so I restored the iPad in iTunes and it sat overnight and today it seems fine.
