well, i got everything finished up .. put the unit back together, plugged in cables, powered it on and ... black screen.
i'm thinking it's either the SX point or the points from my first post .. i wasn't able to get a good multimeter readout from any resistors, (including the SX) though. do they have an enamel or something?
also .. for testing purposes .. is there anything wrong with plugging the unit in without reassembling it? as long all the wires are in the right place, it should work, correct?
