OK at the test points I have: 1.01V, 0.0001V, 0V, 13.1V
should I have 5v?
Eh. I think the 5 volt circuit was on some boards and not others. Technically it's only needed for the LCD display, whatever that was. However lack of 3.3 volts will end it.
Resistance between ground and:
1v = 41ohm
3.3v = 0.20 ohm
5v = 2.9k ohm
12V = 2k ohm
Yep, confirmed short on the 3.3 volt line. Given that all of the chips use 3.3 volts it could be anything. I'd say do an RMA on it, but I do wonder what blew up the 3.3 volt line.
