This is the board from a digital to analog TV receiver that is not working. See the empty pad, middle bottom? I pulled a bloated electrolytic off of there. I stupidly forgot to mark the polarity before I removed it.
With the board powered up, there is a small voltage on the thru-holes and the polarity is in alignment with the shaded area being ground. Maybe 1.5V. The cap is rated 16V.
I thought the shaded area indicates ground, but I swear the the capacitor was mounted backwards, if that was true. I'm about 90% sure of that. Is it possible it was installed backwards and lasted a year or so anyway?
