      Hi all, I finally got around to testing out the almost assembled SPII (only pods remain to be done. When I powered the unit on and program it, I see download is successful. If I push an amplifier select, the relay flips. I hear staging of relays a few seconds after powerup. I checked the voltage at TP204 and it is 5.01 volts. I also adjusted the contrast with R301. Short of pulling it all apart looking for solder bridges, anyone have any ideas. Note that the LCD is lit, just no text.
