So after a little bench testing I swear its the oled, if i turn on the unit (hold down play button)with garbage on screen the relays chatter (sometimes)if i remove the oled I can hear the unit turn on and i can cycle through inputs ( relays switching tested with DMM) without any issues. Voltages seem fine 5vdc across all inputs and it works (its actually usable) except for oled not coming on.Tried a capacitor across D, nothing. Oh well I guess its just a waiting game for now.
