I've an odd situation where the input seems to be drawing nearly 20mA (~22V across a 1k2). I've., at least temporarily, run out of things to check and am wondering if anyone else has seen something like this. I have ~23V5 at the input to the resistor R82 of the switch input filter and a little over 1V on the other side of the resistor. I've checked two boards, both are behaving in the same fashion. As a last stab in the dark I removed the capacitor (C70) on the input filter in case the caps were all bad. As expected that didn't help. The power pad is connected to the ground plane. DB0 and DB1 are floating (read about 4V5).
I don't really expect that there's an obvious chip issue but in case I've missed something or this triggers some recall by someone I thought I'd ask before I dig on the board some more.
